In the prop handling process of stage performances, stage manual hoists are indispensable auxiliary equipment. They are frequently used by staff to lift, hoist, and reposition various stage items, including stage backdrops, lighting trusses, and decorative props.
During performances, the stage is crowded with personnel and the workflow is intense. In the event of sudden equipment failure, on-site rescue and emergency response will be extremely difficult, which may expand the scope of damage. Therefore, post-operation maintenance is by no means a dispensable procedure but a core line of defense to ensure the safe operation of the equipment. After each operation, users must promptly conduct comprehensive maintenance on stage manual hoists: clean dust and debris from chains, hooks, and other components; inspect for signs of loosening, deformation, or wear on parts; verify that the brake system responds sensitively; and replenish lubricating oil for transmission components when necessary. These measures ensure the equipment always remains in optimal working condition, fundamentally avoiding the risks associated with high-altitude operations and safeguarding the safe and smooth execution of stage performances.
