Precautions during installation and dismantling of crane spreaders

cranespreaderDuring installation and dismantling, you must understand the necessary precautions, so as to make the maintenance and hoisting process more convenient, safe and reliable. While improving the efficiency of maintenance operations, you can effectively reduce the safety risks during the operation and greatly reduce the installation, disassembly and maintenance of spreaders. The various costs of the operation.

① When installing and dismantling the spreader, balance arm fences, railings, pull rods, etc. should be used for protection and seat belts and other safety protection equipment should be fastened.Before operation, you should carefully check whether the safety facilities used are firm and reliable.

② Anti-skid measures should be taken in rainy and snowy weather. When the wind speed is above 10.8m/s and under lightning, heavy rain, fog, etc., no high-altitude operations for tower crane maintenance are allowed.

③ Professional installation and disassembly units should provide qualified safety helmets, safety belts and other necessary personal safety equipment for special operations personnel, and workers should wear and use them correctly.

④ When installation and dismantling personnel at high altitudes are working, contact signals or communication devices should be set up, and a dedicated person should be assigned to direct on-site installation and dismantling.

⑤ When installing, dismantling and repairing hoisting equipment, it is necessary to ensure that the rotation of the tower crane is completely braked. For normally open rotary braking tower cranes, manual braking should be performed mechanically to prevent the tower crane from not braking due to rotation. And it swings with the wind, causing hoisting safety accidents.
