5.1.1
Check if the connections are correct, the steel ropes are not damaged, the
clamping are correct, the nuts are tightened, the front beam overhang is in accordance
with the standard. Make sure that the moment of force of the stability of the
suspension mechanism is over two times of the overturning moment.
5.1.2
Check if the wiring is correct. The voltage of power should be within the range
of 380V
5%. After the power is connected, push the testing button on the power
leakage breaker, and power leakage breaker should work swiftly. Close the door of
