Most cranes in duty cycle operation require a:

In duty cycle operations, which involve repetitive lifting, moving, or placing of loads without attaching them to hooks, a load test is essential to assure that the crane is functioning safely and efficiently under its expected operating conditions. Conducting a load test verifies that the crane can handle the specified loads with the required safety factor, thereby confirming the integrity of the crane's structural components and its lifting equipment.

Load tests are performed before the crane is put into service and periodically thereafter, ensuring that it meets the necessary standards for performance and safety. This is particularly vital in duty cycle performances where the operational demands can vary significantly and place additional strain on the equipment.

While load line deductions, critical lift plans, and deductions of rated capacity are important in other contexts, they do not directly address the need for confirming the load-bearing capability of the crane in duty cycle operations as effectively as a load test does. Thus, the requirement for a load test is paramount in maintaining operational safety and efficiency in these scenarios.
