Vibration Information Compact construction equipment is generally used in harsh environments. This type of usage can expose an operator to uncomfortable levels of vibration. It is useful to understand exposure to vibration levels when operating compact equipment and what can be done to reduce vibration exposure. As a result, equipment operation can be more efficient, productive and safe. An operator’s exposure to vibration occurs in two ways: • Whole-Body Vibration (WBV). • Hand-Arm Vibration (HAV). WBV issues are primarily addressed in this manual, because evaluations have shown that operation of mobile compact construction equipment on worksites typically results in HAV levels less than the allowed exposure limit of 2.5 m/s2. Member States of the European Union must comply with the Physical Agents (vibration) Directive, 2002/44/EC. Effective control of vibration exposure for an operator involves more than just vibration levels on the machine. The worksite, how the machine is used, and proper training all play important roles in reducing vibration exposure. Vibration exposure results from: • Worksite conditions. • How the machine is operated. • The machine characteristics. Common causes of high WBV levels: • Using a machine that is improper for the task. • Worksite with potholes, ruts and debris. • Improper operating techniques, such as driving too fast. • Incorrect adjustment of the seat and controls. • Other physical activities while using the machine.
Vibration Measurement and Actions The vibration directive places the responsibility for compliance on employers. Actions that should be followed by employers include: • Assess the levels of vibration exposure. • Determine from this assessment if operators will be exposed to vibration levels above the limits stated in the directive. • Take appropriate actions to reduce operator’s exposure to vibration. • Provide operators with information and training to reduce their exposure to vibration. • Keep good records and update operations and training on a regular basis. If the assessment concludes that vibration level exposure is too high, one or more of the following actions may be necessary:
•
Travel across the smoothest parts of the worksite and avoid ruts and potholes.
2. Choose proper equipment for the job: • • • •
Use machines with the proper power and capacity. Select machines with good suspension seats. Look for controls that are easy to use. Ensure good visibility from the operator’s position.
3. Maintain the worksite: • • •
Smooth ruts and fill potholes in traffic areas whenever possible. Clean up debris frequently. Vary traffic patterns to avoid exposure to rough terrain.
4. Maintain equipment. Check that seat suspension and all controls work smoothly and properly.
Vibration Levels See “Vibration Levels” on page 120 for a table listing typical whole-body vibration levels for the machine.
Fire Extinguisher Location An installation location for a fire extinguisher is shown in Figure 1. Important: Installat ion of a fire extinguisher according to DINEN 3 must be performed by an authorized dealer.
Figure 1 – Fire Extinguisher Location
Note: A fire extinguisher is neither included as standard equipment nor available as an option from Manitou Group. Important: Inspect the fire extinguisher at regular intervals as recommended by the fire extinguisher equipment manufacturer.
Manufacturer Information Products described in this manual are manufactured by Manitou Group. Note: Not all models and options described in this manual are available in all areas.
1. Train operators: • Perform operations (accelerating, steering, braking, etc.) in a smooth manner. • Adjust the controls, mirrors and seat suspension for comfortable operation. Do not make adjustments when the machine is in use.
