① operate each mechanism of the tower crane respectively, observe the height limit, trolley travel limit, crane travel limit and rotation limit, and check whether the limit switch is consistent with the running direction, and can accurately operate the power-off, otherwise it should be adjusted.

② conduct a comprehensive inspection on the wires, cables and their connections of all parts of the whole machine. Especially at the joint, bend and contact with high temperature of the wire, strengthen the inspection. These places are most likely to break the wires and damage the power supply, so it is necessary to focus on the inspection and timely handle or replace the new wires and cables in case of any hidden danger.
③ make each motor run in turn to check whether it starts and runs smoothly and normally, and whether there is noise. At the same time, observe the speed regulation of multi speed motor and slip ring motor. If any problem is found, find out the cause and solve it.

④ respectively move the controller of hoisting, slewing, trolley and crane to check whether the operation direction is consistent with the actual operation direction. If not, adjust it.
