How to hoist the 57-meter-high steel elevator shaft separately or once?

The hoisting of the 57-meter-high steel frame elevator shaft is realized by the following steps.

1. According to the size, weight and surrounding environment of the elevator shaft, determine the hoisting scheme, including the hoisting equipment used, the position and number of hoisting points, the length and number of lifting ropes, etc.

2. According to the hoisting scheme, install hoisting equipment. In general, it is necessary to build a crane frame and install a crane on the flat ground near the elevator shaft.

3. Determine the lifting points: Determine the location and number of lifting points, which are set at the top and bottom of the elevator shaft respectively. According to the hoisting scheme, the hoisting points are fixed on the supporting structures at the top and bottom of the elevator shaft.

4. Fix ropes at lifting points: fix lifting ropes at each lifting point and tighten the ropes with cranes.

5. Hoist the elevator shaft to the target position: start the crane and slowly lift the elevator shaft along the lifting rope until it reaches the target position. In the process of lifting, the stability and balance of the lifting rope should be maintained to avoid the elevator shaft from shaking or tilting.

6. Fixing the elevator shaft, that is, fixing the elevator shaft at the target position, including connecting the elevator shaft with the supporting structure, and making necessary adjustments and corrections to ensure the stability and safety of the elevator shaft.
