COOLING AR 2435539 - Caterpillar

Sound Level Information for Machines in Eurasian Economic Union Countries
The declared dynamic operator sound pressure level is 80 to 84 dB(A) when "ISO 6396:2008 is used to measure the value for an enclosed cab. The measurement was conducted at 70% of the maximum engine cooling fan speed. The sound level may vary at different engine cooling fan speeds. The measurement was conducted with the cab doors and the cab windows closed.The dynamic operator sound pressure level for the canopy is lower than 84 dB(A) when "ISO 6396:2008" is used to measure the value.The declared exterior sound power level (LWA) is 94 dB(A) when the value is measured according to the dynamic test procedures and the conditions that are specified in "ISO 6395 — Dynamic Test". The measurement was conducted at 70% of the maximum engine cooling fan speed. The sound level may vary at different engine cooling fan speeds.The declared sound levels listed above include both measurement uncertainty and uncertainty due to production variations."The European Union Physical Agents (Vibration) Directive 2002/44/EC"
Vibration Data for Compact Track Excavator
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 compact track excavators.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 impossible to obtain. 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.
