FAN 1421929 - Caterpillar

Sound Level Information
The operator Equivalent Sound Pressure Level (Leq) is 81 dB(A) when "ANSI/SAE J1166 OCT 98" is used to measure the value for an enclosed cab and the engine cooling fan was operating at full speed. This is a work cycle sound exposure level. 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 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.The average exterior sound pressure level is 82 dB(A) when the "SAE J88 Feb2008 - Constant Speed Moving Test" procedure is used to measure the value for the standard machine. The measurement was conducted under the following conditions: distance of 15 m (49.2 ft) and “the machine moving forward in an intermediate gear ratio”.Sound Level Information for Machines in European Union Countries and in Countries that Adopt the "EU Directives"
The information below applies to only the machine configurations that have the "CE MARK" on the Product Identification Plate.The dynamic operator sound pressure level is 75 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab and the engine cooling fan was operating at full speed. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed."The European Union Physical Agents (Vibration) Directive 2002/44/EC"
Vibration Data for Track Loaders
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 loaders.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 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.
