Which type of operations can lead to a significant reduction in a crane's load capacity?

Duty-cycle operations can lead to a significant reduction in a crane's load capacity primarily because these operations involve repetitive lifting and lowering actions, which can place additional stress on both the crane's structure and hydraulic systems. In this type of operation, the crane may be required to lift loads at or near its maximum capacity multiple times within a short timeframe. This consistent strain can result in overheating of the hydraulic systems, fatigue of structural components, and potential wear on the hoisting equipment, all of which can diminish its overall lifting capability.

It's important for operators to understand that continuous operations, especially those that push the limits of the crane's rated capacity over an extended period, can compromise safety and lead to operational failures. Therefore, monitoring and managing load capacities during duty-cycle operations is crucial to maintain both safety and functionality of the crane.
