(2) After the tower crane is installed, it shall undergo technical inspection and adjustment of the whole machine, and it shall be delivered for use only after the whole machine has passed the inspection in phases. In the absence of load, the vertical deviation between the tower body and the ground must not exceed 4/1000. The motor and hydraulic parts of the tower crane shall be carried out in accordance with the relevant provisions concerning electric motors and hydraulic devices.
(3) The metal structure of the tower crane, the track and the metal shell of all electrical equipment shall have a reliable grounding device, and the grounding resistance shall not exceed 4 Ω, and a lightning avoidance device shall be set up.
