First, check the performance of the tower crane facilities, check the bolts and pins of the tower crane boom, brake, slewing support and other key parts, if found loose should be tightened in time. Make sure that the bolt does not loosen and fall off before the normal construction work is allowed!
2. Before the work should focus on inspection: no deformation of the main frame structural parts of the tower crane without falling off, the tower crane parts should operate normally, the tower crane reducer, hydraulic tank level should meet the requirements, the tower crane brake device, alarm device, lighting device should be normal and effective! The crane driver should check whether the controller handle of the distribution box is in zero position before working, and check whether the metal parts of the crane have leakage after electrifying!
