Sound Level Information for

Machines in European U nion

Countries a

nd in Co untries that

Adopt the “EU Directives”

The static operator sound pressure level is 76 dB(A)

when “ISO 6394:1998” is used to measure the value

for an encl

osed cab. The cab was properly installed

and maintained. The test was conducted with the cab

doors and the cab windows closed.

Hearing protection may be needed when the

machineisoperatedwithanopenoperatorstationfor

extended

periods or in a noisy environment. Hearing

protection may be needed when the machine is

operated with a cab that is not properly maintained or

when the

doors and windows are open for extended

periods or in a noisy environment.

Vibration Data for Articulated Trucks

Infor

mation Concerning Hand/Arm Vibration

Level

When t

he machine is operated according to the

intended use, the hand/arm vibration of this machine

is below 2.5 meter per second squared.

Information Concerning Whole Body Vibration

Level

This section provides vibration data and a method for

estimating the vibration level for articulated trucks.

Note: Vibration levels are inﬂuenced by many

different parameters. Many items are listed below.

•

Operator training, behavior, mode, and stress

•

b site organization, preparation, environment,

weather, and material

•

chine type, quality of the seat, quality of the

suspension system, attachments, and condition of

the equipment

It is not possib

le to get precise vibration levels for

this machine. The expected vibration levels can be

estimatedwiththeinformationinTable1inorder

to calculate t

he daily vibration exposure. A simple

evaluation of the machine application can be used.

Estimate the

vibration levels for the three vibration

directions. For typical operating conditions, use the

average vibration levels as the estimated level. With

an experien

ced operator and smooth terrain, subtract

the Scenario Factors from the average vibration level

in order to obtain the estimated vibration level. For

aggressive

operations and severe terrain, add the

Scenario Factors to the average vibration level in

order to obtain the estimated vibration level.

Note: All vibration levels are in meter per second

squared.
