How to improve the stability of the semi gantry crane’s lifting points?

The operation of cần cẩu bán giàn is very simple, which makes many users think that the hoisting operation of the crane is not technical, but this is not the case. You can compare novice operators with experienced operators. For some complex hoisting operations, experienced operators can often reduce risks and successfully complete the task, while novice operators often have big problems.

Where are the technical aspects of hoisting operations reflected? The selection of lifting points for semi goliath cranes and the method of tying objects are two of them. The lifting point must ensure that the object remains stable during lifting and placement without flipping, swinging or tilting. The object must have a balanced center of gravity before lifting. This is common sense in semi portal crane lifting operations.

In addition, an object placed vertically has a high center of gravity and a small support surface, and its stability is poor; while an object placed flat has a low center of gravity, a large support surface, and good stability. Therefore, during lifting operations, the shape and center of gravity of the object should be observed and understood to improve Stability of object placement.
