Requirements and matters needing attention in hoisting
Hoisting tower tank by using rotary method or down method, wrist hinge at the bottom of the tower installation must have the ability level of the thrust generated resistance during lifting, the lifting process of the tower body around the ropes must be reliable, the tower height of the rotary position, slowly falling into the foundation, avoid accidents and deformation.

We often encounter equipment installation, transport and installation work, whether the derrick is lifting or hoisting machinery should pay attention to the following points: (1) the indigenous construction equipment for handling mobile rolling method, the rolling rod thickness should be consistent, should buetow annual row width is 50cm long, no gloves in rollers. While loading and unloading piping shall not be greater than 20 degrees slope, raceway erection should be smooth, solid, joints staggered, the rolling speed is not too fast, when necessary to use ropes.(2) in the course of installation, if problems are found, measures should be taken in time, and then continue to be hoisted after treatment.(3) large tower equipment for hoisting derrick, hoists joint operation, the hoist hoisting speed must be roughly the same, to ensure that the tower body of each suspension force roughly uniform, avoid the tower stress uneven deformation.
When the equipment is mounted on a frame or a building, its strength and stability shall meet the requirements of the installation conditions. In equipment installation and location according to the requirements of the drawings are tightly connected or welded, meet the design requirements of the strength and has stability, can be decoupled, otherwise they should be temporary fixed 1. security measures, to prevent the crane from tilting measures (1). The lifting scene road must be smooth solid backfill, soft soil should be processed. If the soil is soft, roads should be paved separately. Parking crane is not working on a slope, also does not allow the crane two side high.
