[Haichuan Equipment Guess] What kind of lifting equipment is this?
Thread Content
In preparation for the hoisting of a large tower, the hoisting workers are installing a kind of tooling on the spreader. I have never seen it before. Have you seen it? @Fish in the desert

After the large crane is fixed, an over-lift must be added before the operation. This over-lift is the counterweight, which is basically 100 tons. Use this over-lift behind the crane. After adding the over-lift, the crane cannot rotate the pole significantly. Install this and start the operation after getting up and off the ground. This is the last preparation process before the large crane operation. Generally used for crawler cranes of 500 tons and above, but 360 tons have also been seen, but rarely.
study* . This is a 260-ton deethanizer tower with a 1,250-ton crawler crane.
Anyone who has done large-scale hoisting has seen the over-lift counterweight of a crawler crane. The position and weight of the over-lift are determined based on the amplitude and load.
