Vibration Data; Introduction; Specifications - jcb 426 Operator's Manual

Introduction

To assist in compliance with European Directive 2002/44/
EC, duty specific vibration emission values for this
machine type have been provided on the following page(s)
and may be used for the assessment of risks to exposure
from vibration.
Unless otherwise indicated for a specific operating
condition, vibration values are determined with the
machine equipped with standard attachments (i.e. bucket,
shovel, fork, etc.) for the respective operating condition.
Vibration values are determined from measurements in
three perpendicular
K Fig 153. ( T 207). The highest weighted (rms) value is
used to specify the vibration emission.
Note: The axis upon which the highest weighted (rms)
value occurs is stated on the vibration chart for each of the
Machine Operating Duties, see Dominant Axis (X, Y or
Z).

Minimising Exposure to Vibration
T5-001
Exposure to vibration can be minimised through:
– Selection of the correct size and capacity of machine,
equipment
application.
– Use of a machine equipped with an appropriate seat,
keeping the seat maintained and adjusted.
– Checks to ensure that the machine is properly
maintained, reporting and correcting any faults.
– Steering, braking,
moving the attachments and load smoothly.
– Adjusting the machine speed and travel path to
Z).
minimize the vibration level.
– Keeping the terrain on worksites where the machine
is working and travelling in good condition, removing
any large rocks or obstacles and filling in any ditches
and holes.
– Choosing routes that avoid rough surfaces and, if this
is not possible, drive more slowly to avoid bumping
and jolting.
– Travelling over longer distances at an adjusted
(medium) speed.
– Avoiding bad postures, i.e. slumping in your seat,
constantly leaning forward or sideways or driving with
your back twisted.
