Vibration Data for Track-Type Tractors
Information Concerning Hand/Arm Vibration Level
When the 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 track-type tractors.Note: Vibration levels are influenced by many different parameters. Many items are listed below.
Operator training, behavior, mode, and stress
Job site organization, preparation, environment, weather, and material
Machine type, quality of the seat, quality of the suspension system, attachments, and condition of the equipmentIt is not possible to get precise vibration levels for this machine. The expected vibration levels can be estimated with the information in Table 1 to calculate the 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 experienced operator and smooth terrain, subtract the Scenario Factors from the average vibration level to obtain the estimated vibration level. For aggressive operations and severe terrain, add the Scenario Factors to the average vibration level to obtain the estimated vibration level.Note: All vibration levels are in meter per second squared.

This publication uses data that is measured by international institutes, organizations, and manufacturers. This document provides information about the whole body exposure of operators of earthmoving equipment. Refer to Operation and Maintenance Manual Supplement, SEBU8257 for more information about machine vibration levels.The Caterpillar suspension seat meets the criteria of "ISO 7096". This represents vertical vibration level under severe operating conditions. This seat is tested with the input "spectral class EM6". The seat has a transmissibility factor of “SEAT<0.7”.The whole body vibration level of the machine varies. There is a range of values. The low value is 0.5 meter per second squared. The machine meets the short term level for the design of the seat in "ISO 7096". The value is 1.61 meter per second squared for this machine.Guidelines for Reducing Vibration Levels on Earthmoving Equipment
Properly adjust machines. Properly maintain machines. Operate machines smoothly. Maintain the conditions of the terrain. The following guidelines can help reduce the whole body vibration level:
Use the right type and size of machine, equipment, and attachments.
Maintain machines according to the manufacturer's recommendations.
Brake and steering systems
Controls, hydraulic system, and linkages
Keep the terrain in good condition.
Remove any large rocks or obstacles.
Fill any ditches and holes.
Provide machines and schedule time to
