What is the maximum lifting capacity a crane should not exceed?

[BraxtonRose]

The load rate of a crane generally should not exceed 60%. Below is an introduction to the dual-height limiter: 1. Introduction to the height limiter: A height limiter should be installed in the lifting mechanism. When the lifting device reaches the designed upper limit position, it should automatically cut off the lifting power source. Above this limit position, there should be sufficient remaining height to meet the requirements of the upward braking distance. A second-level lifting height limiter can also be installed to prevent over-travel and top collision. 2. Hazards of height limiter failure: During operation, if the crane operator fails to monitor the actual lifting height of the hook, it can cause the lifting mechanism to over-hoist and collide with the top, leading to the cutting and breaking of the lifting wire rope, which is the direct cause of the hook and load falling. Failure of the upper lifting limiter is also a significant factor in causing the lifting mechanism to over-hoist and collide with the top.
