1、 Preparation before lifting the electric hoist
Before lifting the electric hoist, a warning area should be established in the lifting area, and the warning personnel should maintain the lifting process. The lifting personnel should be instructed on the process, and the lifting signal should be shared to ensure that the actions of each operating position are coordinated and common, achieving safe construction. The command signal should follow the rules of the “Command Signal for Lifting and Hoisting” (GB5082-85). When lifting, the crane operator uses walkie talkies and gestures to command the lifting behavior. The command signal transmission program is: overall commander, position commander, and operator.
Before operating the electric hoist, the operator should check whether the working conditions meet the requirements, check the obstacles that affect the lifting operation, check the counterweight condition, and confirm the condition of each operating equipment of the hoist; Check if the magnification of the hook, wire rope, and pulley group matches the lifted object; Check the technical situation of the winch, especially the operation status of the safety protection equipment. At the same time, investigate whether the condition of each component is normal, whether the upper and lower pulley blocks are securely and firmly fixed, and whether the steel wire rope is correctly inserted into the pulleys of the pulley block; Is the two inverted hanging points above the replacement winch secure. Only when all parts are functioning properly can normal operations be carried out.
2、 Confirmation of lifting points for lifting components
The total length of the electric hoist is 3.1 meters. After fixing the hook in the center position, the components at both ends are basically the same. Two 3T * 6M lifting straps are used to fix the two ends of the electric hoist at an angle of approximately 60 degrees and find the lifting point to balance the lifting components. After finding the lifting point, check the binding situation of each part and tie the hemp rope to prepare for lifting.
