Forged Strong to LaSt Long. From continuous casters and melt shops to hot and cold mills to galvanizing lines and coke plants, Yates Cylinders are working hard in all areas of the steel industry— designed and manufactured to stand up to the rigorous environment these cylinders must endure every day.

Yates works closely with many companies to help solve their cylinder failures, first determining the cause and in many cases recommending upgrades for a rebuilt cylinder. This process not only eliminates the original problem, it also offers an extended life for the cylinder at a fraction of the cost of a new one.

High heat, debris and dirt are some of the factors our series of Mill Duty, Tie Rod and Round Body Welded cylinders overpower daily in a steel mill.

With three regional locations offering full service capabilities (engineering, welding machining, grinding and assembly) and around-the-clock service, Yates is one of the largest and most complete cylinder manufacturing and repair companies in the country.

An Emerging Workforce Crisis for U.S. Manufacturers A sound recruitment strategy can help small- and midsized manufacturers stay competitive in the hunt for talent By Robert J. LaBombard

PUBLISHER INNOVATIVE DESIGNS & PUBLISHING, INC. 3245 Freemansburg Avenue, Palmer, PA 18045-7118 Tel: 800-730-5904 or 610-923-0380 Fax: 610-923-0390 • Email: Founders: Paul and Lisa Prass Associate Publisher: Marc Mitchell Editor: Kristine Coblitz Technical Editor: Dan Helgerson, CFPAI/AJPP, CFPS, CFPECS, CFPSD, CFPMT, CFPCC - CFPSOS LLC Account Executive: Bob McKinney Art Director: Quynh Vo Director of Creative Services: Erica Montes Accounting: Donna Bachman, Debbie Clune Digital Strategy Manager: Jeff Maile Publishing Assistant: Sharron Sandmaier Circulation Manager: Andrea Karges


Manufacturing companies across the country are searching high and low for trained, experienced workers for drill press, welding, lathe, injection molding, and a myriad of other manufacturing positions. Despite rapidly rising salaries, an estimated 600,000 skilled jobs are unfilled according to the National Association of Manufacturers (NAM). The days of placing help-wanted ads, receiving multiple applications, and hiring the best from a slate of qualified candidates are long gone. What happened? Slowly and gradually over the past 30 years, the number of workers with the required skills for manufacturing jobs has declined substantially. Here are some of the contributing factors: 1. Foreign competition, and the shift of manufacturing south of the border or to Asia, resulted in millions of lost jobs. As result, younger workers were forced to look for jobs in other fields. 2. The Information Age and rapid growth in technology produced high demand and plentiful jobs for people with information-technology skills. 3. High schools and vocational schools shifted curricula away from metalworking, woodworking, and similar “shop” coursework and shifted resources into computer, software, and high-tech education. 4. Public perception placed more emphasis on the four-year college degree and its pathway to a high-paying, so-called “white-collar” career. Fueled by more financial-aid money, college application and matriculation rates substantially increased. These and other factors decimated the demand for training in skilled manufacturing trades among young people. Clearly, we’re paying the price today. Despite the current situation, there is room for optimism in making the manufacturing trades more attractive. Consider these facts: 1. According to government statistics, only about 55% of the people who enter college actually graduate within six years. While the cost of college is clearly an issue, it’s safe to say that college probably isn’t the best post-secondary educational option for a lot of high school graduates. 2. Data from various sources indicates that as many as 80% of new college grads are leaving campus without professional jobs using their degree. While most will find jobs, it is estimated that as many as 50% will be underemployed. 3. About 70% of new college grads don’t know where their education and skills can be applied in the workforce (i.e., they don’t know what jobs are a fit). 4. The average entry-level job for new grads pays around $40,000—far less than what a skilled-trades job might pay for a high school grad at 22 with 3-4 years of experience. A college education is still a fantastic investment for a lot of young people after high school. However, college is not the best option for everyone, as the above information suggests. While college is not the right answer for all high school graduates, I firmly believe that all of them should have some type of post-secondary education.

Success in any type of recruiting is all about the law of supply and demand. The more qualified candidates you have, the easier it is to fill open positions. With this in mind, industry groups and companies can do more to increase the supply of people with the right skills and education. Here are five things that manufacturing industries can do now to increase the availability of skilled workers: 1. Government, broadcasters, and industry associations could collaborate on advertising and/or public service announcements providing education on jobs and career opportunities available in manufacturing. 2. Local chapters of industry groups and member companies could visit high schools and vocational schools to promote careers in their industries. 3. Local chapters of industry groups and member companies could offer to provide financial support to fund the development of jobs-training curricula in the manufacturing trades. 4. Companies could sponsor internships to support high school and vocational training. 5. Industry professionals could support political candidates who support the manufacturing trades and the development of effective educational programs in the trades. While these initiatives will not provide instantaneous payback, it doesn’t take long for an intern or apprentice to make an impact after receiving a two-year degree from a quality vocational technical college. Manufacturing jobs are once again in high demand, offering great pay and attractive benefits. With interest in these jobs battered over the years, industry trade groups and member companies have much to offer and be proud of. The key to success moving forward will be to aggressively promote the opportunities available and to invest in high-quality educational programs. Once understood, for many younger job seekers, the manufacturing trades will be their career path of choice.

Drive the Pro Power Motorsports Team as the National Hot Rod Association Season Begins HYDRAULIC, ELECTRICAL, AND VEHICLE GROUPS HELP BUILD A COMPETITIVE CAR


aton launched its sponsored National Hot Rod Association (NHRA) Pro Power Motorsports team for the 2015 season. Kicking off the season with the Detroit Autorama Car Show, taking place March 6-8 in Detroit, Mich., the team will put Eaton’s hydraulic, electrical, and vehicle solutions to the test. “With one of the only pro-level cars with a torque-converter-driven transmission, the Top Alcohol Funny Car was considered an underdog in 2014, yet we smashed through the ranks to achieve a runner-up position in the 60th-annual Chevrolet Performance U.S. Nationals Event,” said Todd Robertson, driver and owner, Pro Power Motorsports. “Eaton’s engineering experts have continuously helped our team understand the pressures, flows, temperatures, and technologies required to make a torque-converter-driven transmission competitive at this level of racing.” Since the team was founded in 2001, Pro Power Motorsports has relied on the Power of One Eaton – a combination of solutions from the company’s hydraulic, electrical, and vehicle groups – to build a competitive car. Eaton components on the car include the following: ƒƒ Hydraulics Group – Eaton supplied 100% of hoses and fittings used on the car, including Aeroquip® StartLite® hoses, which are flexible, high-temperature hoses that are also flame retardant to improve driver safety in the event of a fire or crash, and Synflex® nylon tubing, which is manufactured from raw materials instead of reground products and prevents air pockets from forming. Even

in the tough conditions on the racetrack, the team experienced no hose failures in 2014. The group also supplied quick-disconnect valves, which make changing the moving components between runs faster and easier. ƒƒ Electrical Group – Eaton supplied switches, toggles, and pushbuttons that regulate electricity in the car and help eliminate “ghost problems”—electrical issues where systems are not working or data is not being collected. With Eaton’s switches, 100% of Pro Power Motorsports’ ghost problems have been solved. ƒƒ Vehicle Group – Engineers worked with the team to build a custom supercharger that could achieve the massive 3,000 horsepower (hp) required for the racecar to run up to 250 miles per hour. The group also provided the engine lifters. “The success of the Pro Power Motorsports team has been exciting to see, and we look forward to the challenges and successes of the 2015 season,” said Mike Rasnick, business development manager, hydraulics, and Eaton’s Pro Power Motorsports team representative. “Our products and engineering inputs have helped transform the team from weekenders to professionals, while the team is continuing to help spread the word about Eaton’s performance products in and out of the racing world.” The Pro Power Motorsports’ 2015 race season will begin with the NHRA Lucas Oil Drag Racing Series regional race, May 1-3, at Lucas Oil Raceway in Indianapolis, Ind. The team will participate in regional and national events throughout the year, culminating with the 61st-annual Chevrolet Performance U.S. Nationals, September 2-7, also at Lucas Oil Raceway.

Economic Report

Global Manufacturing Update By Chad Moutray, Chief Economist, National Association of Manufacturers (NAM) Manufacturers are facing some significant headwinds from sluggish growth abroad and from a U.S. dollar that has strengthened sharply over the past few months. According to the Federal Reserve Board, the trade-weighted U.S. dollar index against major currencies has risen from 75.6968 on July 1 to 91.5660 on March 6, a 21% increase. Along those lines, the euro has fallen to its lowest levels since January 2003. It peaked in 2014 on May 6 at $1.3924 for each euro. On March 12, it closed at $1.0640 to the euro, with some expectations that it will move to parity soon. It last reached parity in November 2002. Overall, these developments could hurt the ability of manufacturers in the United States to grow exports. (Some recent comments from me in the media on this topic can be found in the Financial Times, The New York Times, and The Washington Post.) Reduced crude oil prices have posed another challenge. Beyond the negative impacts seen throughout the energy sector and its supply

chain in the United States, lower petroleum prices have also hampered growth in Canada, our largest trading partner. The Royal Bank of Canada (RBC) Canadian Manufacturing PMI dropped from 51.0 to 48.7, its first contraction since March 2013. Canada was one of two countries among our top 10 markets for U.S.-manufactured goods—the other being Brazil—that had negative sentiment in February. Each slipped below the threshold level of 50 in their PMI values for the month, with China and Hong Kong shifting into the growth column this time. In contrast to these nations, Mexico and the United Kingdom had the fasted paces of expansion in their manufacturing sectors among our top 10 trading markets last month. Despite some challenges, the global economy continues to expand modestly. The J.P. Morgan Global Manufacturing PMI edged marginally higher, up from 51.7 in January to 52.0 in February. This marks the fastest pace in four months. This measure not only reflects improvements in the U.S. economy, but also some incremental progress in China, Europe, and the emerging markets. Each had slightly better data on new orders and output. Yet, weaknesses persist. Eurozone real GDP grew 0.3% in the fourth quarter, or 1.3% on a year-over-year basis. In addition, industrial production in the Eurozone declined 0.1% in January. Many observers continue to worry about deflation, with the latest annual inflation data showing a decline of 0.3% in February, exacerbating those concerns. Moreover, the unemployment rate remains elevated at 11.2%. It is for that reason that the European Central Bank will spend 1 trillion euros over the next 18 months to help stimulate the European economy as part of its quantitative easing program. Meanwhile, manufacturing activity in China bounced back from two straight months of decline, but its economy continues to decelerate. After growing 7.3% year-over-year in the fourth quarter, China has reduced its target real GDP growth rate for 2015 to 7%. Along those lines, a number of recent indicators have reflected slower paces of growth. This included industrial production, fixed asset investments, and retail sales. Investments from manufacturers have fallen from 13.5% year-over-year in December to 10.6% in January/February. It is worth noting that each of these growth rates is strong relative to other nations, but the challenge is that growth remains much less than what we have become accustomed to for China. Action of trade legislation, particularly Trade Promotion Authority (TPA), is now expected in the April-May timeframe, as efforts to negotiate a bipartisan, bicameral TPA bill continue. New legislation reauthorizing the Export-Import (Ex-Im) Bank has been introduced in the House, while work on crafting a bipartisan Senate bill continues. Other manufacturing legislative priorities are also

stacking up. Trans-Pacific Partnership (TPP) talks are ongoing in Hawaii this week, and the next round of the U.S.-EU talks move forward in mid-April. Efforts to negotiate sectoral tariff-cutting talks and broader multilateral talks are ongoing at the World Trade Organization (WTO). Product-specific export control reform also continues.

The National Association of Manufacturers (NAM) represents small and large manufacturers in every industrial sector in all 50 states. For more information, visit

Infinite increment locking of the die platen protects the operator and machine via a Sitema safety catcher (picture: Mueller Weingartenag Esslingen).




he Sitema safety catchers from Advanced Machine & Engineering Co. (AME), Rockford, Ill., stop and lock a dropping platen via a wedge mechanism located on a smooth rod that can be placed in any position and that is activated by the weight of the dropping mass.

Some machines are equipped with safety devices that operate in only one or a few positions, such as interference rods or linkage mechanisms. The upper platen must travel the full stroke even if a fraction of the stroke would be sufficient for production reasons. With such devices, total safety cannot be guaranteed. If, for example, an emergency stop or a power failure occurs in the middle of the full stroke, the latching device cannot be activated. With multiple-ratchet-position devices, it is questionable whether or not the ratchet will properly engage and withstand the forces of the dropping mass. Installing safety catchers on hydraulic presses and other machines in which dropping masses are a concern can eliminate such dangers. Infinite position locking is an advantage. These safety catchers lock the mass to a smooth round bar.

The safety catchers can be used not only on hydraulic presses, but also on any other machines or devices in which dropping masses must be stopped for safety reasons. They include vertical-axis devices of machine tools, portals, material-handling systems, and platforms in theaters or amusement park rides. The safety catchers are certified by the German TÜV to comply with DIN EN 693 standard as lift-secure devices. Other certifications also are available upon request. Exotic clamping problems also can be solved with Sitema special devices for low- or high-quantity applications to satisfy even those customers with complicated requirements. MORE INFORMATION IS AVAILABLE AT WWW.AME.COM.



The load is secured by stopping the dropping mass using the weight as a means to wedge the safety catcher against the acting hydraulic cylinder rod or a separate catcher rod. The locking capability is proportioned to the dropping mass: the heavier the dropping mass, the stronger the grip.

drops, the safety catcher is set to automatically secure any dropping load.


The full-locking force is created only by the load. The unit will lock only when the safety catcher is in the locking position (no hydraulic or pneumatic pressure is present) and the load is moving downward (such as when the acting hydraulic cylinder of the press is leaking).

Safety Focus


An Employer’s Guide to Hydraulic Safety Awareness Training By Colin Bonner, Founder and CEO, Hydraulic Safety Authority of Canada (HSAC) Inc.

Many occupational standards and regulations explicitly require employers to train employees in the health and safety aspects of their workplace. Occupational Health and Safety standards make it the employer’s legal responsibility to limit certain tasks to employees who are certified, competent, or qualified—meaning that they have completed special training to perform specific duties and are aware of the related hazards. Training must be a part of every employer’s health and safety program for protecting workers against injuries and illnesses.



Research has shown that workers who are new on the job have higher rates of incidents and injuries than more experienced workers. The Hydraulic Safety Authority of Canada (HSAC) Inc. has developed training guidelines to assist employers and personnel in providing health and safety information needed to reduce risk to workers, the public, and the environment when hydraulic equipment is used. The development of these guidelines can assist employers in their efforts to meet the training requirements of current and future occupational health and safety standards. • May/June 2015 •

To determine whether or not hydraulic safety training should be incorporated into a company’s health and safety training program, employers should begin by determining whether or not hydraulic systems are used by employees either within or outside of the facility. The following questions can be used to help make the determination: ƒƒ Do we use hydraulics in our facility for plant processes? ƒƒ Do we have mobile or construction equipment? ƒƒ Do our employees maintain equipment that utilizes hydraulics? ƒƒ Do we have employees who work within one meter of a hydraulic system or component? ƒƒ Do our employees operate equipment that utilizes hydraulics in public areas? ƒƒ Do we operate hydraulically driven equipment in fragile ecosystems? If employers are unable to answer these questions or determine with certainty whether or not hydraulic equipment is being utilized by their employees, they may need to consult with others within the company. If it is determined that hydraulic equipment is being utilized, employers must determine who is at risk of being injured from hydraulic exposure. One way to identify employees who are at risk of exposure, and therefore require training, is to consider an employee’s occupation and specific duties. The nature of the duties and tasks performed will indicate which employees should receive priority information on hydraulic safety. Some employees are employed in high-risk occupations, but even within hazardous occupations, some personnel operate at greater risk than others. Once employees who are at risk of hydraulic exposure have been identified, they should be enrolling in the level of training that is best suited to their specific needs. The following guidelines are intended to help determine an employee’s level of exposure to hydraulic hazards in the workplace, however, it is important to realize that hydraulic hazards do exist outside of the workplace, as well. Outside of work, people may be exposed to tractors, lawnmowers, wood splitters, jacks, power and tilt on steering in boats, brakes on vehicles, and rental equipment that all utilize hydraulics. Hydraulic systems are a way of transmitting energy, which together with the loads they manipulate, are extremely hazardous. Therefore, maintenance, reliability, ethical choices, and knowledge play a substantial role in risk reduction.

EDUCATIONAL REQUIREMENTS BASED ON LEVEL OF EXPOSURE TO A HYDRAULIC HAZARD The following three-part scale can be used to determine an employee’s training needs based on his or her level of exposure to hydraulic equipment.

FOR MORE INFORMATION: The mission of Hydraulic Safety Authority of Canada (HSAC) is to provide proactive health and safety awareness programs specific to hydraulic systems and components. These programs provide a guideline for companies to follow as they show the necessary due diligence required for providing a safe work environment and improving their existing health and safety systems. Contact by phone: 416-363-7272; e-mail:; web: The IFPS is now an authorized provider of HSAC’s Hydraulic Safety Awareness e-learning courses.

Less Likely

GREEN SCALE In this situation, hydraulic hazard exposure is low, as the employee does not work within one meter of a hydraulic system. Recommendation: Exposure-Level Training.

Medium Risk

YELLOW SCALE In this situation, an employee is exposed to a moderate level of risk of hydraulic hazard exposure because he or she works within one meter of a functioning hydraulic system, operates equipment that utilizes hydraulic systems, or may come into contact with hydraulic fluids. Recommendation: Exposure-Level Training.

Most Likely

RED SCALE In this situation, hydraulic hazard exposure is high because the employee maintains and repairs hydraulic systems and components, has physical contact with hydraulic components and fluids, or completes tasks that include designing, assembling, commissioning, decommissioning, or demolishing equipment that utilizes hydraulic systems. Recommendation: High-Risk Maintenance-Level Training.

Figure It Out

Scrap Steel Winder Problem Slowing Down Workers at a coil steel-processing mill received rolls of stainless steel from its parent company to slit in half and trim the edges approximately 1" to 2". They recoil the sheets and ship them to their OEM customer that fabricates stainless steel refrigerators. They have a hydraulic motor-driven unit that coils the scrap edges of the coils onto drums. This operation needs to keep up with the speed of the splitter, or the scrap starts to “bunch up,” which requires the workers to stop the line and remove the excess manually. The hydraulic unit was over 20 years old and needed updating. A local hydraulic distributor built them a new unit, and the mill did the installation. During commissioning, they found that the new unit could not keep up with the slitter line speed as the scrap coil increased in diameter. The unit was upgraded from a fixed-volume open-circuit design to a closed-circuit pressure-compensated pump design to improve energy efficiency. The only other difference was the use of a flow-control module under the pilot-operated directional valve. The old unit had line-mounted flow controls. The builder convinced the mill that it must be the mill’s existing motor leaking more flow to the case, as the pressure increased when the scrap steel diameter increased, causing the motor to slow down. They then replaced the hydraulic motor with a new one, but they still had the same problem.

The only difference that we saw was the male 37º fitting used as an SAE #8 male boss. Looking into the quick-disconnect female port, there was a center piece that was part of the assembly. It finally dawned on us that the 37º fitting was longer than an SAE of the same thread, and this extra length caused the center hole in the fitting to be too close to the QD center piece, creating a restriction. We milled the nose of the fitting, and it worked great. Using 37º fittings as O-ring SAE bosses works well if there is room for the O-ring to seal AND the longer nose doesn’t interfere when assembled.

Safety Focus


Fluid Injection Injury By Dan Helgerson, CFPS-Certified Fluid Power Specialist, CFPSOS, LLC, and Fluid Power Journal Technical Editor When I was working for a mining company, I realized an area that everyone could learn and/or refresh their knowledge in was safety, and with this in mind, I researched and investigated fluid injection injuries. The International Fluid Power Society (IFPS) believes that implementation of safe procedures is paramount in all fluid power systems, the electrical and electronic controls that guide them, and all associated technologies. IFPS recommends that, in every circumstance, factory, piece of mobile equipment, or application of any fluid power product or its controls, every employee and employer is responsible to know, understand, and practice the safety policies and procedures already in place. Consult manufacturers’ safety specifications for each machine. Take the responsibility to improve the safety standards whenever an opportunity presents itself. No one knows the equipment better than the people who work with it daily – they are the most important ones to improve that equipment’s safety!



ƒƒ Prevention is always the best treatment. Know the proper operation and maintenance of all equipment. ƒƒ Comply with all rules and requirements established by the particular manufacturer and site where the work is being performed. ƒƒ Use personnel protective devices: face shields or safety goggles, ear plugs or covers, safety shoes and clothing that is suitable for the environment. Wear gloves when handling hot materials or to protect hands against hot surfaces. BE PREPARED IN THE EVENT OF A FLUID INJECTION INJURY

ƒƒ IFPS offers safety cards that contain five critical pieces of information for doctors and emergency medical technicians in treating fluid injection injuries. ƒƒ IFPS offers a free Web seminar - “In The Line Of Fire” - which is available to the public ƒƒ IFPS offers free safety posters for download compliments of the IFPS and HSAC*. Visit ƒƒ IFPS offers Online Hydraulic Safety Awareness Training Courses (fee based). Courses provide an awareness of hydraulic hazards in the workplace, in-depth reviews of potential exposures to injury from hydraulic systems, and ways to reduce risk and eliminate hazards for workers, equipment, companies, and the environment. Courses offered: ƒƒ Hydraulic Safety: Exposure Level Online Course ƒƒ Hydraulic Safety: High Risk Maintenance Level ƒƒ Hydraulic Safety in Construction Overview ƒƒ Fluid Injection Awareness

Doctors may not be experienced in treating injection injuries and therefore may underestimate the urgency of this type of injury. It can take hours to locate a qualified medical professional. Your best chance at proper treatment is to locate a hospital or hand surgeon who is experienced with this type of injury in advance and “Fantastic Hydraulic Safety Awareness Training have contact information readily available. Your company should be prepared to have the Material Safety Data Sheet (MSDS) available whenever an injury occurs. KNOW BEFORE YOU GO

video, and I am convinced that it saved our company from a very serious injury. I used the information gleaned from the video to conduct a lunch and learn on injection injuries. The very next week, a maintenance worker that took the class saved a contractor from grabbing a hydraulic hose to stop a pinhole leak. The contractor was within inches of grabbing the hose when my worker physically pulled him back and educated him on injection injury dangers.



The “Know Before You Go” theory is vital to receiving proper treatment. IFPS offers a safety card to all its members and certified professionals that provides five critical pieces of information to communicate to the medical staff. (Safety cards can also be purchased.) Posters are also available. 1. What type of fluid? (Provide the Material Safety Data Sheet.) 2. What is the amount of fluid injected? As a follow up, we have changed our 3.

Professional Development

Influence: The Ultimate Power Tool By Dr. Robert Cialdini, Ph.D

In business today, effective influence is essential. Want your ideas implemented? You must influence others to act on them. Want more clients? You must influence people to buy from you. Want more advancement or responsibility? You must influence executives to see the value you offer. And to be an effective leader, you must be able to influence others. In all respects, being able to influence others is the ultimate power tool. So, what makes people say “yes” to your requests? Researchers have been studying influence for over 60 years. While it’s nice to think that we are all logical beings who study facts and information to guide our thinking and decision-making process, scientific research shows otherwise. Following are the six proven universal principles of persuasion, that when used ethically, can influence others to change their behavior.



RECIPROCITY There’s a powerful rule that says that we should try to repay what others have done for us. If someone gives us a gift, we feel compelled to give a gift in return. If someone extends us an invitation, we should extend one to them. And if someone does us a favor, we owe them a favor in return. By virtue of the Reciprocity Principle, people feel obligated to the future repayment of items, actions, favors gifts, and concessions. You see Reciprocity initiated in business every day, even if you don’t immediately recognize it. From suppliers sending relevant industry-specific information to clients, to managers providing personalized guidance, to co-workers helping each other meet a deadline, Reciprocity can be initiated in many ways. The key to effectively using Reciprocity is to be the first to give and be sure that your “gift” is personalized and unexpected.

SCARCITY Have you ever noticed that people seem to want more of those things they can have less of? That’s the Scarcity Principle at work. • May/June 2015 •

Marketers know the power of this principle, which is why their ads often contain such phrases as “Limited Time Only” or “Limited Quantities Available.” When true, Scarcity affects the value of information, too. In other words, information that is exclusive is more persuasive. So the next time you gain access to information that is not readily available and that supports an idea or initiative you would like the organization to adopt, gather the key players and say, “I just got this information today. It won’t be distributed until next week, but I want to give you an early look at what it entails.” Your listeners will lean forward and listen intently. The key to using Scarcity successfully, whether for a product, service, or information, is to not just honestly tell people the benefits they’ll gain, but also point out what’s unique and what they stand to lose if they don’t move in your recommended direction.


AUTHORITY Research shows that people typically follow the lead of those they perceive as credible and knowledgeable experts. For example, physical therapists are able to persuade more of their patients to comply with programs if they display their medical diplomas on their office walls. That’s because people tend to defer to legitimate experts for information and guidance on what to do. Surprisingly, people mistakenly assume that others recognize their experience. To ensure that they do, first determine what your relevant background, experience, and expertise are for the person you are trying to influence. If you don’t do this, you will be sabotaging the power of your own message. For maximum impact, arrange to have a third party communicate this information. Another option is to direct the person you want to influence to something in writing that highlights your credentials (i.e., LinkedIn profile, your bio on your website, etc.). The key to using Authority successfully is to signal to others what makes you credible and knowledgeable before you make your influence attempt.


CONSISTENCY People feel compelled to be consistent with their prior behaviors or statements. When someone makes a commitment actively, either by writing it down or speaking it out loud, it’s even more likely that they’ll follow through with that commitment. You can activate the Consistency Principle by looking for or asking for small initial commitments. For example, suppose you want a coworker, Jim, to submit his reports in a timelier manner. Once you believe you’ve won agreement, ask him to send you a summary of that decision in writing. By doing so, you’ll have greatly increased the odds that he’ll fulfill the commitment, because people tend to live up to what they’ve written down. The key to using Consistency successfully is to look for voluntary, active, and public commitments … and get them in writing.

EXERT YOUR INFLUENCE TODAY Influence is a very powerful tool. When you ethically implement these six scientifically validated principles of persuasion, you’ll be making small, practical, and often costless changes that can lead to big differences in your ability to change others’ behavior. In the end, you’ll not only achieve your objectives, but you’ll also guide the other party to the best decision for their needs. That’s when true success emerges for everyone involved.

About the Author INFLUENCE AT WORK (IAW®) was founded by Robert Cialdini, Ph.D, Professor Emeritus of Psychology and Marketing and author of the New York Times bestseller, Influence. Dr. Cialdini is a keynote presenter on the ethical business applications of the Science of Influence. Additionally, IAW offers customized, in-house Principles of Persuasion (POP) Workshops conducted by Cialdini Method Certified Trainers. For availability please call 480-967-6070, visit, or follow on Twitter at @robertcialdini.


LIKING People prefer to say “yes” to those they know and like. But what makes someone like you? Science tells us there are three important factors that contribute to likeability: 1) we like people who like us (and tell us so); 2) we like people who are similar to us; and 3) we like people who cooperate with us toward mutual goals. The key to using Liking successfully is to be honest in your praise, find genuine similarities, uncover opportunities to work together toward common goals, and get to know people more meaningfully before talking business.


SOCIAL PROOF Humans are social creatures. And as such, we rely heavily on the people around us for cues on how to think, feel, and act. In other words, people look to the actions of others to guide their own. This is why using testimonials from happy and satisfied customers is so effective in marketing campaigns. You can use Social Proof when attempting to get your ideas implemented. Imagine that you’re trying to streamline your department’s work processes, but a member of your group is resisting. Rather than try to convince this group member yourself, ask a couple of veteran employees who support the initiative to explain their support for it at a team meeting. The veterans’ testimony stands a much better chance of convincing the resistant group member than yet another speech from the boss, as Social Proof is often better exerted horizontally rather than vertically. The key to using Social Proof successfully is to have similar others present their positive story to your target; this is why testimonials are so effective. CIRCLE 475 • May/June 2015 •

PIRTEK Burnsville Assists with Local Farming Innovation PIRTEK Burnsville in the Minneapolis area was contacted by Brian and Gary Pahl, the fifth-generation owners of Pahl’s Market, to upgrade a piece of farm equipment. A few years ago, Brian Pahl recognized the need for a conveyor belt on his farm and envisioned reusing the irrigation unit to make it happen. He reached out to the Burnsville hose service center, and Jeff Quast, mobile sales and service technician, discussed how to turn one of the old field-irrigation units into a conveyor belt to collect peppers grown on the farm. PIRTEK added hydraulic hoses, motors, and return lines to the irrigation system, which created a 50-ft. machine that stretches 16 rows long. The new conveyor belt allows the Pahls and their team to collect crops faster than with previous methods. Within three days, the team figured out the fittings and adapters, ordered the necessary parts, and assembled the machine. With the conveyor belt installation, the farm is able to collect twice the amount of crops within half the time.

HOISTS Facilitate Crane Repairs on Offshore Platform

When the diesel engine of a deck crane failed, it caused major handling problems for an offshore platform operating in the Dutch sector of the southern North Sea, problems that were solved with the use of air-operated hoists. The crane was operating at 40 meters above sea level and provided a lift capacity of 20 metric tons. Replacing the broken engine, which weighed in at approximately 2750 lbs, presented some logistic problems. The diesel engine replacement operation was successfully undertaken by Gerritsen On- & Offshore Services BV Company from its base in Amsterdam, with the work being completed in approximately one week. As the replacement engine was too large and heavy to be ferried by helicopter, a lifting device was needed that met requirements, such as being explosion proof, lightweight, and which could easily lift the replacement safely from the supply vessel. The suitable lifting device was sourced from the J. D. Neuhaus range of air-operated hoists available in the Gerritsen rental fleet. It was a Profi 2TI model that had a lift capacity of 2 metric tons. This model is available as standard with a 3-meter lift, having an overall weight of approximately 240 lbs, including the control system. This product was easily modified to provide the 40-meter lift required onsite, involving an additional weight for the twin-chain hoist mechanism at approximately 4.5 lbs per meter run. With the replacement engine and its lifting equipment being transported by a supply vessel (16

hours sea time), provision was required for an additional primary lifting unit to handle the Profi 2 TI hoist and its 40-meter drop of twin chains utilized for the major lifting operation. Once again, equipment that was light enough to be delivered to site by helicopter was selected from the Gerritsen rental fleet. This was a J. D. Neuhaus air-operated Mini hoist, providing 2200-lbs lift capacity to handle the larger and more powerful Profi hoist and its 40-meter chains. The Mini hoist, plus an appropriate beam clamp for the hoist suspension support, was helicoptered in (30 minutes air time) and mounted ready for the primary lift operation of the Profi hoist and chains utilizing a big bag container. The more powerful Profi unit was then used to replace the Mini hoist, utilizing the same beam clamp installation. The Profi hoist with a 2-metric-ton lifting capacity was then utilized to undertake the more difficult lift and location of the replacement diesel engine utilizing a sling assembly. The work was undertaken with one rig person for safety inspection, together with one rigger and three scaffolders. The range of air-operated hoists is universally deployable, incorporating explosion protection, and are suitable for use in hazardous areas. The Mini series is available in load capacities of 275, 550, 1100, and 2200 lbs together with a manipulator version providing for one-handed operation of lift, lower, and hoist-traverse operations. These products are explosion protected and feature an Ex classification of Ex II 3 GD IIA T4. The Profi series hoists offer a more rugged build quality for heavier-duty operations and can be supplied with lift capacities from 550 lbs up to a full 100 metric tons. Duty rating of 100% and unlimited duty cycles are provided as standard, ensuring no down time and low maintenance requirements. They are supplied as standard with classification Ex II 2 GD IIA T4 / II 3 GD IIB T4, with increased spark protection to Ex II 2 GD IIB T4 and for explosion group IIC: Ex II 2 GD IIC T4. These products are insensitive to dust, humidity, and temperatures ranging from -20°C to +70°C. They also provide infinitely variable speed controls for the precise positioning of loads.

SOLVING <CROSS TALK> BETWEEN SENSORS By H.G. Schaevitz LLC, Alliance Sensors Group


hen LVDT signal cables are bundled together or laid close to each other in a wire trough, even for short distances, the result can be a mutual interference phenomenon called “heterodyning” (or “beating”). This effect is created when the frequencies of the oscillator in the individual signal conditioner driving the excitation signal to each LVDT differ slightly. Since the signal cables are close together, there can be capacitive coupling among them, resulting in very low beat frequency signals that are the difference between the frequencies of the individual oscillators. The beat frequency signals can ride on the DC output of the LVDT signal conditioners, appearing as low-frequency ripple or noise with a period measured in fractions of a second, or as a repetitive slow drift with a period of many seconds. When a pair of LVDTs is used together for redundancy, this effect may be evident on only one channel of the system, but in systems with larger numbers of LVDT channels, this effect may be found in one or more channels, depending on many factors like cable length and layout, as well as shielding and grounding. The typical way to solve this beat frequency problem in multiple-channel systems is to create a “master oscillator” by using the oscillator from one of the signal conditioners to supply the same excitation frequency to all of the LVDTs. The oscillators in the other LVDT signal conditioners are overridden by the master and operate as “slaves.” The idea is that there cannot be any beat frequency interference if all the LVDTs are operating at exactly the same frequency. Table 1 shows an example of the drifting over time resulting from a beat frequency on the left side of the graph. The waveform in the output was noted in the right-hand reheat and stop valve hydraulic cylinder-operated valve positioners that were using dual-redundant LVDTs for valve position feedback to the steam turbine control system in a power plant. On the right side of the graph, the beat frequen-

cy effect was eliminated by utilizing the master/slave function, and the waveform flattened out. The master/slave approach works quite well, but has a major drawback because the “redundant” system is no longer fully redundant. The system is now dependent on one oscillator in one signal conditioner to supply all the LVDTs with the proper excitation frequency. If the master fails, two things could happen: either the other channels stop operating, or they revert back to their original oscillator frequencies and the multiple-channel DC outputs now display beat-frequency-produced noise, ripple, or output drifting. Many companies offer LVDT signal conditioners with a master/slave function, but they all are fully susceptible to this particular beat frequency problem if the designated master oscillator falters or fails. Alliance Sensors Group (ASG) gave very serious consideration to this beat frequency problem in multiple LVDT installations and developed a successful solution to the problem that is incorporated in its Model S1A LVDT signal conditioner. Because the S1A module and its variants include a digital address for RS-485 communication capability, ASG is able to use this digital feature to maintain full redundancy in multiple LVDT systems. If the “master” were to fail, another master having a different digital address would immediately come on stream to maintain a single excitation frequency. With this approach, the only thing lost from a master oscillator failure is the original master channel itself. For multiple-channel LVDT systems, the integrity of the output signals from the other channels is fully maintained. This “auto-mastering” feature is unique to Alliance Sensors’ S1A LVDT signal conditioner module and its variants.

Shorter Stroke Lengths Make


LVDT LINEAR-POSITION SENSORS Ideal for Hydraulic Cylinder Applications By Michael Marciante, Applications Engineer, Macro Sensors

Pumps · Motors · Valves · Servo/Proportional


he development of computerized layer winding and improved microprocessing has considerably reduced the body length of the linear-position sensor compared to its measurable stroke length. With the improved stroke-to-length ratio (now up to 80%), the LVDT linear-position sensor becomes a viable position-measurement device for hydraulic cylinder positioning. The role of the cylinder in most hydraulic applications is to move “something,” such as a valve, airplane tail rudder, or a boom or shovel on an off-road vehicle. In these applications, the control system needs a feedback device that tells it how far the cylinder or actuator moved to ensure proper operations. That’s where the linear-position sensor comes in. Installed within or outside the cylinder, the LVDT tracks the movement of actuators and reports data electronically to a control system that can monitor and provide alerts on operating conditions. For example, if a pilot wants to turn the plane, he moves the joystick. The plane’s control system senses that he has moved the joystick and sends a signal to the tail rudder actuator to move the tail rudder. If the system has no way of knowing how far the actuator has moved through position feedback provided by an LVDT linear-position sensor, the plane could turn too much or not enough. A second example would be a robotic arm. In this scenario, let’s say the robotic arm is going to move to pick up a piece of glass. If the control system does not know when to stop the arm by receiving position feedback from an LVDT linear-position sensor, the hydraulic cylinder could drive the arm right through the piece of glass. Care should be taken in choosing the right LVDT linear-position sensor for an application. While miniature LVDTs are suitable for high-response dynamic measurement, hermetically sealed LVDTs are ideal for environments that experience high-pressure wash down, dust, and in some cases, submersion. Many modern LVDTs can serve as cost-effective replacements for magnetostrictive technology that are somewhat more expensive over shorter ranges and have difficulty handling large shocks. Table 1 compares the characteristics of LVDT linear-position sensors to magnetostrictive technology in different ranges.
