Detailed explanation of the maintenance process for stage chain hoists (Part 1)
In stage performances, the stage hoist is an important lifting device that can help staff quickly and safely lift and move various stage props and equipment. However, due to prolonged use and frequent operation, stage chain hoists may experience various malfunctions and require timely maintenance. Next, let's take a detailed look at the maintenance process of stage chain hoists.
1、 Fault diagnosis
(1) Appearance inspection
Firstly, conduct a visual inspection of the stage chain hoist to check for any damage, deformation, or cracks on the outer shell, as well as any wear, deformation, or breakage on the hooks, chains, and other components. If obvious damage is found on the appearance, it should be immediately stopped from use and further inspection and repair should be carried out.
(2) Functional testing
Perform a functional test by pulling the zipper tape to check if the lifting and lowering functions of the hoist are normal. Pay attention to observing whether the chain runs smoothly, whether there is any jamming, jumping or abnormal noise. At the same time, check the performance of the brake to ensure that the hoist can brake quickly and reliably when stopping the chain.
(3) Fault analysis
Analyze the cause of the malfunction based on the results of visual inspection and functional testing. Possible causes of the malfunction include chain wear, gear damage, brake failure, and shell rupture. For complex faults, further diagnosis may require the use of professional testing equipment and tools.
2、 Repair preparation
(1) Tools and materials
Prepare corresponding maintenance tools and materials based on the results of fault diagnosis. Common repair tools include wrenches, screwdrivers, pliers, hammers, etc. Repair materials include chains, gears, brake parts, lubricants, etc. Ensure the reliable quality of tools and materials to guarantee the effectiveness and safety of repairs.
(2) Security measures
Necessary safety measures must be taken before carrying out repairs. Ensure that the repair site is clean and unobstructed, and avoid accidents during the repair process. At the same time, wear necessary personal protective equipment such as gloves, helmets, goggles, etc. to protect your own safety.
