1. Workers entering the construction site must wear safety helmets;

2. The crane is not allowed to stay under the hoisting state.

3. When the column is hoisted, the column shall not be detached from the crane when the operator does not completely close the anchor bolt nut;

4. When climbing the sky, the staff must wear a safety belt and use a safety rope to prevent accidents.

Component installation security misapplication:

1. Strictly check the lifting components of the crane.

2. Strictly check the lifting point components of the column.

3. Strictly check the lifting point components of the steel surface structure, and strengthen the hanging parts of the problem to ensure that the hanging points are not left in safety.

Component hoisting staff safety misplacement:

The lifting and hanging points of the board are set at the end of the beam and the angle of the board, so that the board is balanced as much as possible when lifting, and the board is lifted from the ground to the upper end of the column and then the board is rotated to make the board support column and column. The upper end is vertically suspended and aligned. At this time, the operator is required to assist the operation. One to three employees are equipped with a belt to climb to the opposite position of the column. The fastening belt is fastened to the deck girders, and then the crowbar is used. Position, the position is accurately commanded to hang in time, the crane is placed in place smoothly, and the welding personnel at high altitude begin to weld. The safety rope worn by the high-altitude welding personnel during the operation, the safety belt must be firmly connected with the steel structural members of the brand surface, and the value and the anti-welding spark behind the body are protected against the safety rope and the safety belt. The joint is welded firmly to allow the crane to evacuate

(1). Identify the safety production responsibility of construction personnel at all levels. Construction management personnel at all levels must determine their own safety responsibility objectives and implement the project manager responsibility system. Implement a safe one-vote veto system.

(2). The lifting tool should be firm and reliable, and the tools with qualified quality should be selected. Do a good job of the test crane, and hoist it after confirming that there is no problem. Safety helmets must be worn when entering the site, and safety belts must be worn at heights.

(3). Lifting bulk items must be bundled firmly and kept in balance before lifting.

(4) Non-electromechanical personnel are strictly prohibited to use electromechanical equipment.

(5). Adhere to the safety fire inspection system, find hidden dangers, eliminate in time, prevent work injuries and fire accidents.
