Whole-Body Vibrations - Volvo EC15E Operator's Manual

Operating techniques

Whole-body vibrations

Whole-body vibrations
Whole-body vibration emission on construction
machinery are affected by a number of factors, such
as working mode, ground conditions, speed, and so
on.
To a large extent the operator can influence the
actual vibration levels, because the operator
controls the speed of the machine, its working
mode, the travel path, and so on.
Therefore, the result can be a range of different
vibration levels for the same type of machine. For
cab specifications, see page
Guidelines for reducing vibration levels on
earthmoving machines
Use the proper type and size of machine, with
optional equipment and attachments for the
application.
Keep the terrain and haul roads in good condition.
- Remove any large rocks or obstacles.
- Fill any ditches and holes.
- Provide equipment and schedule time to
maintain terrain conditions.
Adjust the speed and travel path to minimize the
vibration level.
- Drive around obstacles and rough terrain
conditions.
- Reduce the speed when it is necessary to go
over rough terrain.
Maintain machines according to the
manufacturer's recommendations.
- Track tension.
- Brake and steering systems.
- Controls, hydraulic system and linkages.
Keep the seat maintained and adjusted.
- Adjust the seat and its suspension according to
the weight and size of the operator.
- Inspect and maintain the seat suspension and
adjustment mechanisms.
- Use the seat belt and adjust it correctly.
Steer, brake, accelerate, shift gears, and move
the attachments smoothly.
Minimize vibrations for long work cycle or long
distance travelling.
- Use suspension systems if available.
- If no suspension system is available, reduce
speed to prevent bouncing.
