Monthly check and maintenance of construction tower cranes

Tower cranes have to be checked and maintained every month, checking items as follows:

 

Check wear condition and lubricating condition or tower crane wire steel ropes, if can’t reach requirement, should change immediately.

 

Check perpendicularity of tower crane body. Safety devices, like four limiters, two insurances, must be safe, flexible and reliable. If hear abnormal sounds, should stop and repair, then can re-start to work. Before operation of tower cranes, must empty load switch contacts of safety devices and ensure them be in right position.

 

When tower crans are out of work, relax brake devices of slewing mechanisms, let hook lift near to hoisting jib, and anything isn’t allowed on the hook.
