GB/T 16937-2020Earth-moving machinery--Operator's field of view--Test method and performance criteria (English PDF)

1 Scope

This standard specifies the boundary rectangle and 12m visibility test circle (VTC) used to determine and evaluate driver visibility around the machine

The static test method.

This standard applies to earth-moving machinery that is defined by ISO 6165 and that travels on construction sites and on highways and has a seated driver position. this

According to the type of machine family in Table 1, the standard specifies the performance criteria for the visibility of various machines that reach the maximum work quality of ISO 6165.

For machines not listed, including large machines, derived earth-moving machinery and other types of earth-moving machinery, the visibility test procedure can be

Refer to the implementation and use it in conjunction with the risk assessment procedures defined in 10.4.
