Electric chain hoists are widely used in lifting operations due to their lightness and practicality. However, the details of their use directly impact safety and equipment lifespan, requiring strict compliance throughout the entire process.
Pre-operation inspection is the first line of defense for safety. Focus on inspecting the lifting chain to ensure it is free of cracks and deformation, and that the surface is properly lubricated and not dry. The hook's locking mechanism must be intact, firmly engaged to prevent slippage, and the hook itself must be free of cracks or bends. For manual hoists, rotate the hand chain wheel to check for smooth operation and reliable braking. For electric hoists, test-start the motor, listen for any unusual sounds, and confirm that the load will not slip under braking. Also, ensure that the suspension points are secure, the work area is clear of obstacles, and the equipment's load capacity is suitable for the operation.
During operation, perform precise and cautious operations. Before lifting, gently lift the load to a height not far from the ground, pause briefly to check the equipment's condition, and only proceed if all is clear. The hook must be aligned with the center of the load to avoid tilting. During operation, keep the chain vertical and never pull or pull at an angle. When manually pulling the chain, apply force at a constant speed, and minimize frequent powering on and off of electric hoists. Always monitor the equipment during operation, and immediately stop and investigate any unusual noises or jams.
Post-operation maintenance is key to equipment durability. Clean grease and debris from the chain and hook promptly, and reapply lubricant to prevent rust. Place the hoist in a dry and ventilated area. After unloading, disconnect the power cord from the electric hoist and keep records of its use to eliminate potential hazards for the next operation.
