Before hoisting, the electric hoist should set up a warning area for the hoisting area and guard the personnel to maintain the hoisting order, and clarify the procedures for the hoisting personnel, unify the hoisting signals, and pass the signals to ensure that the actions of all operating positions are coordinated to achieve safe construction.
Determination of the lifting point of the hoist: The total length of the electric hoist is 3.1m. After the hook is fixed in the middle position, the weight of the two ends is basically the same. Use two 3t*6m slings to fix the two ends of the electric hoist at an angle of about 60° and find the balance of the hoist. Of hanging points. After finding the lifting point, check the lashing of each component, and tie the slip rope (hemp rope) to prepare for lifting after the check is correct.
The hoist lifts the hoist to the level of DMC7 and stops the hoist, and hangs it on the inverted chain of the hoist with a 5T inverted chain hook prepared in advance. Remove the shackle on the hoist and place the hoisting piece on the 7th floor platform. After the hoisting piece is placed firmly, remove the 5T inverted chain. Use the two-point hoisting method to use the 5T and 2T inverted chain respectively. Use the hoisting points at both ends of the hoisting piece to lift the hoisting piece. Raise to the installation height and complete the installation.
