Scope

This part of GB/T 7121 specifies the dynamic test methods and acceptance criteria for protective devices of agricultural and forestry wheeled tractors. The purpose of the protective device test is to minimize the possibility of the driver being injured in a rollover accident when the tractor is operating normally. The strength of the protective device is tested by applying loads to the cab or safety frame when the tractor is simulated to roll over backward or sideways (except for free fall). This test can check the strength of the tractor's protective device and connecting brackets, as well as the strength of those tractor parts that may be affected by the loads applied to the loading device.
