What does dual lifting points mean for a crane?
2 Answers
Crane dual lifting points refer to two lifting points attached to the crane's main hook, using four wire rope slings to ensure lifting safety. Here is the relevant content introduction: Crane: Commonly used wire ropes for cranes include phosphating coated wire ropes, galvanized wire ropes, and stainless steel wire ropes. For use in atmospheric environments, the patented manganese-based phosphating coated wire rope has the longest service life. Current fatigue test data shows that the fatigue life of phosphating coated wire ropes is approximately 3-4 times that of smooth wire ropes of the same structure (under comparable laboratory conditions). The reasons for the significantly extended service life of wire ropes are their resistance to wear and corrosion, far surpassing imported wire ropes. For highly corrosive environments, hot-dip galvanized and phosphating dual-coated wire ropes are the preferred choice.
As a regular customer at an auto repair shop, I often see workers operating those cranes to lift things, like this dual-lift-point type, which essentially has two hooks or two lifting positions, used to hoist big items like engines. Last time my car's engine failed, they used this dual-lift-point method to lift it out steadily without any wobbling, making it much safer. The advantage is that it distributes the weight, preventing parts from getting misaligned or stuck, especially when working under tight car spaces, avoiding any side-slipping that could injure people. I think everyone should pay attention to this detail when repairing cars—choosing the right lifting points reduces accidents, and regular maintenance can prevent rust and loose connections. In short, it makes hoisting more reliable, saving money and effort.
