Whole-body vibrations

Whole-body vibrations
Whole-body vibration emissions on construction machinery are af-
fected by a number of factors, such as the working mode, ground
conditions, speed, etc.
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, etc.
Therefore, the result can be a range of different vibration levels for
the same type of machine. For cab specifications, see page 118.
Guidelines for reducing vibration levels on
earthmoving machines
Use the proper type and size of machine, with optional equip-
ment 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 recommen-
dations.
– 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 travel-
ling.
– If no suspension system is available, reduce speed to pre-
vent bouncing.
– Transport machines when there are long distances be-
tween worksites.
