How much should the load chart be reduced when doing cycle work?

50%
20%
30%
None

The correct answer is: 20%

When engaging in cycle work, which involves repetitive lifting and lowering of loads, the load chart should be adjusted to account for dynamic factors that can affect the crane's performance and stability. Reducing the load chart by a specified percentage, such as 20%, serves to ensure the safety and integrity of the lifting operation. This reduction is based on the understanding that while the load may not appear significantly different from a static lifting scenario, the dynamic forces at play during lifting, swinging, and lowering can impose additional stress on the crane. By lowering the maximum load that can be safely handled, operators can better accommodate these dynamic forces, reducing the risk of tipping, overload, or equipment failure. This approach reinforces the importance of using conservative figures to ensure the lifting operations meet safety standards while accounting for potential fluctuations during repetitive lifts associated with cycle work. The percentage reduction helps operators to maintain a margin of safety, thereby prioritizing the well-being of personnel and equipment.
