Introduction

This standard is a type C standard EN1070 prescribed.

This standard is intended to provide a measure of industrial vehicles passed into the method of whole-body vibration of the operator to meet the Machinery Directive's information Claim. This standard is intended to measure the results obtained with the same type of industrial vehicle or a vehicle of the same industry but with different seats, Tires were a contrast. This standard does not apply to the actual operation of the daily load measuring vibration to the operator.

For measurement, the vehicle shall be provided by the manufacturer of the vehicle in the standard configuration parameters specified on the list of the equipment (lifting devices, batteries, etc.).

Type tests require accurate and repeatable results. Different test results comparable agency within a predetermined range is important of. This requires the measurement process and test methods for mechanical to be exact requirements. This process may be repeated using the machine in normal operation Typical values \u200b\u200bof whole-body vibration.

For industrial vehicles, there are three main modes of operation. running, lifting and engine idling. These three modes, the only mode of operation the operator is exposed to severe whole-body vibration. Therefore, in accordance with EN1032, whole-body vibration test based on the operating mode.

Studies have shown that hand-arm vibration acceleration value of the vehicle steering wheel or lever is usually less than 2.5m/s2. Therefore, there is no arm vibration Test methods.

In fact, the vibration value of the daily work is a mixture of three modes of vibration and the average value is typically lower than the present standard given vibration. work Industry vehicles with different seats, changing tires, etc. will give rise to different vibration. However, due to special handling vehicle industry, the existing the EN1032 can not be directly used to measure vibration values, so the need to develop this standard.

Although studies have shown that the test off-road industrial vehicles in the artificial test track available repeatable and representative test results, but Appendix A vehicle according to a series of process, because. when an industrial vehicle at two different times of the year to do the test and found that the vibration measured Values \u200b\u200bare approximately 20% of the difference can not be explained. As more data are available, should further consider the off-road industrial vehicles included in the present Standard body part.

For verification measurement uncertainty must be specified in accordance with the vibration emission values \u200b\u200bEN12096 reported 0.3 times. When eligible from different places Vibration radiation data obtained can be used, it should consider further revisions of the uncertainties.

Safe vibration measurement methods for industrial vehicles

1 Scope

This standard specifies under given conditions, Test Method for Measuring the industrial operator of the vehicle body vibration transmitted to. It does not include hand Arm vibration.

This standard applies to GB/T 6104-2005 listed in the motor industry and other motor vehicles are not included in GB/T 6104-2005 in Industrial vehicles such as forklifts and telescopic low lift picking trucks. Appendix A is suitable for off-road industrial vehicles.

NOTE. The standard for industrial vehicles in use also have reference value.

This standard does not apply to GB/T 6104-2005 in 3.1.3.2.3,3.1.3.1.11 defined by low lift non-stacking straddle and heap High stack lift straddle.

The results do not apply to the determination of whole-body vibration load.
