Safety technology for transportation and stacking

Safety technology for block transportation and stacking

1) when entering the site, you must wear a helmet, buckle the hat belt, and correctly use personal labor protection appliances

2) there should be a firm foothold at the hanging operation place, and protection, railings or other safety facilities must be configured according to the specific situation

3) riggings, scaffold boards, baskets, cages, platforms and other equipment used in suspended operations can only be used after technical appraisal or verification

4) before going to work, all kinds of lifting machinery and equipment, ropes, fixtures, temporary scaffolds and other construction safety facilities should be checked, especially whether the relevant parts of the fixture are flexible and reliable, whether the fixture automatically pulls up after the scissors fixture is suspended, whether the splint teeth or rubber blocks are worn, and whether the garbage in the splint teeth is removed. The fixture should also be regularly checked and tested for relevant performance, such as distortion, cracks, and when the majority of customers buy the experimental machine, 1 we must carefully consider the wear of the plate, and should be repaired in time, not reluctantly used. Before using the new fixture, it should be carefully accepted, the size should be accurate, and the performance test should be carried out

5) before clamping the block, check whether the block is stable. If there is any deviation, pry it right before clamping. The splint of the fixture is on the center line of the block to prevent the block from skewing after lifting; In the process of block lifting, it is strictly prohibited to continue lifting the block if it is found that there is a partial fracture and there is a risk of falling off. When the lifting swing rod rotates, it is strictly forbidden to stay the block above the operator or repair or handle the block in the air. No one is allowed to stand or perform other operations under the swing rod and hook. No other work is allowed on the lower floor during block hoisting. When lifting heavy components with the scaffold, the scaffold should be added with a stable rope

6) after the scaffold or other floor cranes, crane equipment, etc. are in place, check whether the position, weight, anchor mouth of cable, etc. of these equipment meet the requirements before hoisting. When hoisting blocks or other components, the construction of pier column is mainly to control its verticality, and attention should be paid to the position of the center of gravity of the lifted object. The lifting capacity shall be strictly controlled within the allowable range, and the turning radius and luffing angle of the lifting pull rod shall be strictly controlled. It is not allowed to lift blocks or other components behind the front pillar of the spirit rack, and it is not allowed to put long slings to drag blocks or components. When the block is hoisted for horizontal rotation, it should be pulled by the operator to avoid swinging and collision with the wall or temporary scaffold

7) the place where blocks are unloaded and stacked should be flat, free of sundries and blocky objects, so as to prevent individual blocks from falling down and hurting people after the fixture is loosened. When unloading and stacking blocks on the floor, try to avoid impact, and it is strictly forbidden to tilt and hit the floor. The stacking of blocks shall be as close to the end of the floor as possible. The reserve of blocks on the floor should be, and the Journal of natural research materials published research on this work. Considering the bearing capacity and deformation of the floor, the floor load should not exceed the allowable bearing capacity of the floor, otherwise corresponding reinforcement measures should be taken, such as adding support at the bottom of the floor, etc

8) when the block is hoisted in place, the fixture can be loosened only after the block is placed stably

9) in case of the following conditions, the hoisting operation should be stopped:

① when the signal cannot be heard clearly

② when unsafe factors such as lifting equipment, riggings and fixtures have not been eliminated, o

③ when there is heavy fog or insufficient lighting

during winter construction, the snow and frost in the machinery, scaffold board and operation area should be removed before work operation. It is strictly prohibited to lift blocks and components frozen with other materials (5 points should be 20%, 40%, 60%, 80% and 100% of Zui's heavy load)
