What is load testing in the context of mechanical engineering?

Load testing in mechanical engineering refers to the process of applying a specified load to equipment or structures to verify their strength, stability, and safe working capacity. This testing ensures that lifting equipment, structures, and mechanical systems can safely handle the intended load under actual working conditions.

Load testing is commonly performed on equipment such as cranes, hoists, lifting beams, lifting tools, platforms, structures, and material handling equipment to confirm their Safe Working Load (SWL) and operational reliability.
In India, load testing is typically carried out in accordance with statutory requirements under the Factories Act, 1948 and relevant State Factory Rules enforced by the Directorate of Industrial Safety and Health. These regulations require lifting equipment to be tested by a Competent Person at specified intervals.
