L68B1 Mast Section638/5000 Problems needing attention in the construction of tower crane
The construction process of Tower lifting must achieve unified thinking and unified command. According to the relevant operating rules for safe use, the following points should be noted:
1. When lifting and lifting operations, heavy arms must not be turned, and special personnel must be set up for protection;
2. Slant hanging, side hanging, lifting and other measures such as the selection of appropriate suspension position and auxiliary traction;
3. The legs of the lifting equipment used for construction should be hit on a solid ground, with necessary wooden boards or square wood;
4. Check whether the connecting parts of the tower crane are complete, reliable, and effective, and whether the sling equipment is safe or not;
5.2 M above high altitude operations must be safe and protected. Rainy weather and wind power greater than the fifth grade stop operations. When the construction is in the middle of the storm, the tower must be installed in a safe state;
6. The loading and unloading must be carried out in strict order as required by the construction plan. The front of the lifting arm should not be weighted, and heavy weights should not be lifted without assembly. When disassembling, the weight should be disassembled first and then the heavy arm should be removed.
