CAT’S MINEXPO FEATURES SUSTAINABLE EQUIPMENT, TECHNOLOGY
Themed “Together, we’re mining better,” Caterpillar’s MINExpo 2021 experience celebrates the company’s partnership with mines and the ways it assists customers to mine more efficiently, effectively, safely and sustainably.
The 55,000-sq.-ft. exhibit will feature a broad range of product displays, new equipment introductions, previews of what the future holds and remote operating stations.
The exhibit will be grouped under three specific core areas: environmental, social and corporate governance (ESG) and sustainability; technology and automation; and equipment lifecycle management solutions.
“After waiting an extra year, the mining industry is ready to reconnect at MINExpo. We are excited to show our customers and the industry the advancements Caterpillar has made not only in equipment, technology and services but also in how we are helping customers mine more sustainably,” said Caterpillar Resource Industries Group President Denise Johnson.
Mining Sustainably
Central to Caterpillar’s commitment to mining better together is helping customers meet their ESG goals and build sustainable mine sites of the future. Recognizing that one size doesn’t fit all, Caterpillar has followed a strategic approach with a long-term vision of discovering, developing and delivering a broad portfolio of products, technologies, services and solutions.
This portfolio allows Caterpillar to provide a full site approach, which combines offerings with integration expertise to identify and provide the best possible solution for each specific mine.
Vital to the vision of the all-electric underground mine of the future, the new Cat R1700 XE LHD will feature 100 percent battery electric propulsion that generates significantly less heat and noise. It offers a 16.5ton (15-t) payload, 53,330-lb. (24,190-kg) lift and tilt breakout force, and 11.2 mph (18 kmh) top speed. To optimize runtime and improve safety, batteries stay on the machine for charging.
Fully charging the R1700 XE in as little as 20 minutes, the new portable Cat MEC500 mobile equipment charger is the first of its kind in the industry. It can be moved via towing, fork truck or the R1700 XE and eliminates the need for regular battery handling and swapping.
The new R2900 XE LHD diesel-electric drive train on display features a significant reduction in maintenance and repair costs, while minimizing emissions. Its redesigned lift arm and components deliver up to a 39 percent improved lift breakout force over the R2900G, making this model up to 31 tonnes per liter more fuel efficient.
Caterpillar is set to unveil the world’s largest, most powerful and efficient electric drive dozer with high drive. The new Cat D11 XE dozer will be the most advanced, lowest emission-per-ton dozer in the industry, built to deliver the lowest cost of bank cubic meters (BCM) ever. Exhibited alongside the D11 XE, the new Cat D10 dozer offers up to 4 percent less fuel consumption than the previous model, up to 3 percent more productivity with high-horsepower reverse and up to 6 percent more efficiency with combined load-sensing hydraulics and stator clutch torque divider.
The recently introduced Cat 992 wheel loader delivers up to a 32 percent increase in productivity. It reduces maintenance costs by up to 10 percent and has demonstrated infield testing up to 48 percent greater payload-per-fuel efficiency in applications where a four-pass match to 100-ton (90.7-t) trucks was achieved versus five passes with the 992K.
Caterpillar is committed to helping its customers with their energy transitions, and the MINExpo exhibit will include a range of renewable and storable power displays, including the Cat Microgrid system. The Cat 3516 engine will feature dynamic gas blending (DGB), which allows mines to save fuel and reduce emissions without sacrificing diesel performance, according to the manufacturer.
The MD6310 improves drilling efficiency by automating individual drill features and communicating real-time production and health data.
Driving Technology, Automation
Achieving sustainability goals requires mines to continually strive for operational improvement. Fully optimizing operations delivers the highest safety and productivity at the lowest cost and least possible environmental impact.
“Technology and automation are critical components for substantially improving machine uptime availability and productivity,” said Marc Cameron, vice president, Caterpillar Resource Industries.
MINExpo will be the first opportunity for many attendees to learn more about the recently introduced Cat MineStar Edge. It brings visibility to the entire mining operation to show how activities early in the process impact those further down the value chain. MineStar Edge makes it possible to measure, manage, analyze and improve the entire mining operation.
Equipped with MineStar Command for hauling, the new Cat 777G water truck provides a glimpse into the future for autonomously lowering dust levels at the mine site while maintaining haul road safety. Featuring the market’s first autonomous water delivery system, the machine integrates truck, tank and sprayer and knows where and when to water haul roads.
Representing the Caterpillar fleet of autonomous trucks, the displayed Cat 794 AC electric drive will be factory-installed with Cat MineStar Command for hauling. Recently, autonomous trucks using Command for hauling surpassed 3 billion tonnes of material hauled, safely traveling more than 68.3 million mi.
Accurate to the centimeter, the exhibited Cat MD6310 rotary blasthole drill offers technology, efficiency, safety and productivity improvements. Fully integrating Caterpillar’s proven components and systems, including technology and automation, the drill is capable of up to 92,922 lb. (42,149 kg) of bit load and targets 8- to 12.5in. (203- to 311-mm) hole diameters.
Exhibiting how technology can improve safety at the mine site, the Cat MineStar Detect Driver Safety System (DSS) display details how the system monitors eye-closure and head pose to alert the driver via seat vibration and/or audio alarm the moment fatigue or distraction is identified. DSS has been shown to reduce 97 percent of the most significant fatigue events, 80 percent of average fatigue events and 91 percent of distraction events.
Several Cat Command stations and trailers will be on display for attendees to experience effective remote control and semi-autonomous drilling, dozing and underground operations from many kilometers away.
Lifecycle Solutions
From individual offerings to comprehensive solutions, Caterpillar and Cat dealers offer dozens of equipment management services designed to improve overall machine performance and mine site productivity. Component rebuilds, retrofits, aftermarket solutions and service agreements help customers get the most out of their investments. Dealer-provided Customer Value Agreements (CVAs) allow customers to focus on their core competency – mining.
Highlighting Caterpillar’s rebuild services capability, the rebuilt Cat C175-16 engine, which produces up to 3,420 hp (2550 kW), on display reduces overall owning and operating costs.
Team members also will be available to explain to attendees how MineStar Health maximizes equipment availability and reliability by connecting the machine to the office. The service assists with proactive maintenance services and predictive equipment analysis by collecting equipment data, monitoring critical machine parameters, obtaining real-time alerts, analyzing operational trends and patterns, predicting failures and receiving repair recommendations.
Partnership, Expertise
In addition to teams of workers with machine and technology expertise, representatives of Cat Financial and Cat Solutions will be on hand to share information on safety, fleet management and productivity offerings that can be combined into full site solutions.
A ThoroughTec Simulation training will provide an opportunity to experience the 7495 electric rope shovel. In addition, attendees will be able to experience two next generation machine cabs — one for mining trucks and another for the 6060 hydraulic mining shovel — via actual cabs on display.
Caterpillar invites all MINExpo 2021 attendees to visit its Central Hall exhibit, #6229, at the Las Vegas Convention Center from Sept. 13 to 15.

NEVILLE from page 1 ment and preservation work on four sign structures. Additionally, preservation work will occur on the I-79 bridge over Deer Run Road, north of the Neville Island Bridge.
According to Steve Cowan, PennDOT press officer, federal funding was provided for the $42 million project, which began in August 2020, with completion expected by June 2023.
The contract was awarded to Trumbull Corporation, under the direction of Rob Opel.
The bridge first opened in 1976 after five years of construction. It was reportedly the last link to finish the 180-mi. long I-79. It also is the second longest single spanning bridge in Allegheny County.
Jason Zang, assistant district executive of construction, spoke about the project.
“It’s essentially what I would call … I’d say it’s somewhere between a bridge preservation and a bridge rehabilitation project,” he said. “It’s a little bit unique in that respect. It’s more like a rehabilitation project. We’re fully painting the bridge. We’re not painting the entire interchange. We don’t have the funding to do the ramps. There’s a lot of ramp structures associated with this area, but we’re doing all what we call main lines, all the approach spans and the main arch span of the bridge, so we’re painting all of that — a lot of steel.”
Zang said that steel repairs are being done wherever necessary, which involves some areas where water was leaking over the years from some of the joints.
“We’re replacing the joints that had leaking, we’re doing deteriorating concrete repairs, we’re doing patches to the deck like concrete repairs and latex repairs to the deck, so that’s kind of it,” he said. “Mostly paint, a little bit of steel repair, little bit of concrete repair, little bit of concrete deck repair.”
Zang said the work is necessary because of the age of the structure.
“It’s approaching 50 years old,” he said. “It’s never been painted other than some minor maintenance work here and there, but it needs a full paint job. But we have the original paint on the bridge now — we call that an industrial coating system — so that gets completely blasted off to bare metal and then it gets a brand new three coat paint system.”
Zang noted that “a little bit of everything” is currently happening on the project.
“Right now, we are right in the middle of it, so there’s a lot going on,” he said. “A lot of paint work. There’s painting underneath the roadway surface to the structure below what we call the steel superstructure. There’s also painting going on above the roadway to the arch itself, the arch pieces. Everything’s happening right now.”
There will be four total weekend closures of the northbound side in 2021 and four total weekend closures of the southbound side in 2022.
The first of the northbound weekend closures on the I-79 Neville Island Bridge began on Friday night, July 9 through Monday morning, July 12.
Zang also spoke about the challenges to the project, noting the size first.
Another challenge is working over traffic, with almost 80,000 vehicles a day using the bridge.
“We had a lot of careful planning and design to make sure that we were able to build this and not affect traffic too, too much, so we restricted when the contractor can restrict lanes and things like that during the peak travel periods,” Zane said. “We’ve got weekend closures, full closures of Interstate 79. We just had the first one two weekends ago and it went very well, but that’s obviously a very big challenge to our customers and to the public.” Another challenge that had to be solved involved peregrine falcons living on the bridge, which had to be protected. “The Pennsylvania Game
Commission pays a lot of attention to them,” Zang said. “There are people that watch them almost every day and there’s restrictions there that if they were to lay an egg on that bridge, then we would have to stop work. So, we had some provisions in the contract that the contractor had to immediately start putting up the paint containment system and hurry up to get that up before the falcons could nest. So, we were basically shooing them away with our work, and we were successful with that.
Zang said that the crew had to make some adjustments because they didn’t get all the containment up in time. So, they shifted gears and started doing things to basically keep the falcons away, like wrapping all of the connections on the bridge to keep them from nesting there.
Another issue was coordinating with a busy railroad under one of the span. Crews worked on the weekends so there was a bit less train traffic to coordinate with the railroad and flaggers.
As far as unique aspects of the job, Zang said every project is a little bit different. The bridge had steel splice plates on some of the main girder lines. These were primary structural carrying members of the bridge that had some deterioration and were getting replaced, so some temporary towers were added to support them. This was done during the weekend closure so traffic was removed. The critical pieces were disconnected and the new ones added. “Other than that, there’s only one Neville Island Bridge in the world, that’s the one we’re working on,” Zang said. “It’s a little bit different. It’s a unique structure. It’s not like every other bridge out there. We do have a similar bridge, the Birmingham Bridge in Pittsburgh, so we have a little bit of experi-

Like I said, it’s very large long I-79. and has what are called trussed floor beams, so it’s a bit unique of a structure because of its size and its structural components.” Zang reported that the funding and design schedules worked out for them to do another large project last year, the Sewickley Bridge, which is right up the river from the Neville Island Bridge. Each serves as the detour for the other bridge. “And we actually shut down the Sewickley Bridge last summer for 24 days to put a latex modified concrete overlay on the bridge and replace all the expansion dams,” he said. “So, this project had to be closely coordinated — a lot of planning and design to make sure they didn’t overlap.” According to Steve Cowan, PennDOT press officer, federal funding was provided for the $42 million project, which began in August 2020, with compleAnother major resurfacing project was done on Route 65 just to the north of this project, going under the Neville Island tion expected by June 2023. Bridge. In addition, bridge work will be done on I-79 immediately north of this project. “It literally abuts the end of this project,” Zang said. “That’s getting started very soon and we’ve got some other projects. We’ve got a local project that’s occurring on Route 51, which was the original detour to the Neville Island Bridge and we had to switch gears on this project and change the detour route so we could avoid that project. So, there’s a lot going on in that area right now.” He noted the importance of the project and the number of people being employed “Just on the contractor side of things, it’s about 70 people from the contractor union, laborers and carpenters and painters out there and then there’s also the construction oversight, so this project is putting a lot of people to work,” Zang said. “And as I said, the bridge has never been painted, it’s a very large structure. We’ve been doing repairs to it since I started at PennDOT 23 years ago. We’ve been doing steel repairs, things like

OSHA from page 76
The manual stresses acclimatization of workers and teaching them to recognize heat stress symptoms. It also recommends ways to reduce heat stress such as providing shade, cool drinks and changing work schedules to avoid the hottest part of the day.
OSHA will likely seek comment on heat stress thresholds, heat acclimatization planning, exposure monitoring and medical monitoring, according to Bloomberg Law.
The agency turned down petitions to undertake such a rulemaking during the Obama and Trump administrations. But Democrats in the House and Senate introduced companion bills earlier this year addressing the need for a standard.
The bills would mandate that OSHA issue a proposed heat rule within two years of the law’s enactment and issue a final rule within 3½ years. Neither bill has been scheduled for a committee hearing.
In the 2019-2020 congressional session, then-Sen. Kamala Harris (DCalif.) sponsored a similar bill that never came up for a vote.
Announcing the bill, she said, “it is absolutely unconscionable that workers in industries from agriculture to construction face excessive heat conditions for hours each day with no protections for their health and safety.”
Back-Tracking
On Workplace Injury
Contractors can expect to see enhanced workplace injury and illness tracking under the Biden Administration’s OSHA. The agency wants to revert to the 2016 version of the rule.
OSHA’s proposed regulation includes anti-retaliation provisions that could discourage workplace safety and health incentive programs and postincident drug testing, according to Malveaux.
“A reversion could signal that OSHA will view drug testing and incentive programs as a form of employer retaliation,” he said.
“This could have a particular impact on larger construction sites that report more injuries and illnesses because of the sheer number of employees working at a site,” he cautioned. “It also may have an outsized impact as construction employers grapple with marijuana legalization laws and worker intoxication.
“Regardless of the cause, substance and alcohol abuse lead to more workplace accidents and injuries,” wrote Malveaux, noting that dehydration from alcoholism also can lead to several different heat illnesses.
Other Proposals Worth Watching
OSHA has proposed a communication tower safety standard aimed at keeping more tower construction and maintenance workers alive.
A projected increase in tower installations and repairs over the next few years has the agency concerned that the fatality rate has “greatly exceeded that of the rest of the construction industry.”
The goal of the proposal is to greatly decrease that rate as more workers enter the industry. CEG
OSHA will issue a request for information seeking public input on a possible rulemaking on heat illness prevention in October.
