GB/T 14917-1994 Instruments for testing earth-moving machinery

This standard specifies a list of instrumentation guidelines for inspecting earth-moving machinery on site. This standard does not include instruments used to dismantle machinery or in the workshop. This standard applies to crawler and wheeled tractors, crawler and wheeled loaders and hydraulic excavators. Other earth-moving machinery such as graders, self-propelled scrapers and dump trucks can also refer to this standard.

This standard specifies the instrumentation for detecting earth-moving diseases on site - Overview: This standard covers the instruments that have been dismantled from the machine or used in the workshop. GB/T 14917--94
This standard is applicable to belt-type and wheel-type tractors, belt-type loaders, hydraulic excavators, and other earth-moving machines such as self-propelled shovel loaders and self-propelled trucks. 2 Inspection items and instruments
1 stipulates that "each inspection corresponds to an instrument. The meanings of the letters in the table are as follows: A——Required (if the machine has this inspection item) B——Recommended inspection, but not necessary. The recommended gauge for each inspection item is the commonly used internal gauge, and when there is a more advanced instrument, it can also be selected. The range of the gauge or the instrument should be changed accordingly.
