Shanghai replacement dock crane operation

Equipment selection: Sany SAC3000T

Construction difficulty:Because the site is close to the river bank, and the river bank is a stone barrier, it is forbidden to be heavy, and vehicles cannot enter, so they can only work on the inside. The site is very narrow and long, the distance between the body and the lifting items is as long as 40 meters, and due to the height limitation of the plant, the angle of the main boom is too large, and it can only be fully equipped with 140 tons of counterweight full outrigger with overload and overload hoisting. Lifting items need to be transported out of the river. When rotating, the overlift is less than 1 meter away from the plant。

Construction process: outriggers, full extension; Arm length, main boom 81 meters; Lifting weight, 7t; Lifting height, 6.2m; The lifting items are transferred from the river surface, and the overlifting is less than one meter away from the plant.

Customer evaluation: In this construction, the situation is easy to switch, the operation efficiency is high, the slewing performance is stable, and the lifting performance is better.

Lifting parameters:

Lifting weight: 7 tons; Full outrigger length: 81 m;

Lifting height: 6.2 meters;
