VALVE GP-RELIEF 6E1123 - Caterpillar

Sound Level Information
The dynamic operator sound pressure level is 84 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab. The cab was properly installed and maintained. The test was conducted with the cab doors closed.Hearing protection may be needed when the machine is operated with an open operator station for 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 in a noisy environment.Sound Level Information for Machines in European Union Countries and in Countries that Adopt the EU Directives

Vibration Data for Load Haul Dump Machines
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 m/s2.Information Concerning Whole Body Vibration Level
This section provides vibration data and a method for estimating the vibration level for Load Haul Dumpers.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 equipmentPrecise vibration levels for this machine are not possible. The expected vibration levels can be estimated with the information in Table 1 in order 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 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.
