As an indispensable small and lightweight lifting equipment at stage construction sites, stage manual chain hoists are widely used in key links such as stage truss installation, lighting and sound equipment hoisting, and prop material transfer. The safety of their operation is directly related to the progress of the entire stage construction project, the personal safety of on-site personnel, and the integrity of various equipment and materials. Therefore, conducting standardized test lifting operations on stage manual chain hoists before they are officially put into lifting operations is a safety process that must be strictly implemented.
One of the core purposes of test lifting is to verify whether the actual weight of the lifted load is within the rated load-bearing range of the hoist through actual load-bearing tests, ensure that the equipment matches the weight of the lifted load, and avoid potential safety hazards caused by mismatched weights from the source.
No matter how urgent the operation task is, the test lifting process of the stage manual chain hoist must be strictly implemented before each lifting operation. Although this link seems simple, it undertakes the important mission of ensuring personal safety and property safety, and its importance cannot be ignored, let alone arbitrarily omitted for the sake of efficiency. Only by effectively implementing this basic safety process of test lifting can we build a solid safety defense line for subsequent lifting operations and ensure the smooth and safe progress of the entire stage construction work.
