There are many equipment, containers, steel structures, pipelines, modules, etc. in engineering construction projects. In many cases, the installation and removal operations need the help of mechanical tools. Among them, the lifting tool is a commonly used equipment, which plays a very important role in improving construction efficiency, reducing construction cost and reducing operation risk.
China's industrialization, urbanization and economic development have increased the number of construction projects such as buildings, and large-scale construction projects are blooming everywhere. Hoisting operation has also become a very common construction process and step, and the degree of construction mechanization has increased significantly. The popularization of hoisting machinery facilitates the construction, but the safety management in hoisting operation is also highlighted. Hoisting accidents occur frequently, resulting in serious consequences such as personnel injury, equipment and facilities damage, property loss and so on. The dense hoisting equipment of large-scale construction projects and the insufficient hoisting safety management of small-scale construction projects have brought great potential safety hazards to the project safety management.
Sometimes, when inspecting the hoisting of steel wire rope on site, an obvious hidden danger is found, that is, the braided length of steel wire rope is only 5-10 cm, and it is used for hoisting assembled components. Let alone how the safety officer did not find this reason in his work. It seems that the new material collector on the construction site is responsible for the mobilization and acceptance of materials.
Braiding method is the most commonly used end connection method of steel wire rope. It is lifted and transported in Wuxi. This method uses a heart-shaped collar to turn back the end of the steel wire rope first, then braid each strand at the end in each strand of the steel wire rope respectively, braid each strand for 4 ~ 5 times, and finally tie it tightly with thin steel wire.
When braiding is used for fixation, the braiding length shall not be less than 20 times the diameter of the steel wire rope, and shall not be less than 300mm. The splicing rope strand shall be tensioned, the protruding part shall be smooth and flat, and an appropriate length shall be reserved at the end of splicing and fastened with metal wire. If the rope is inserted by other methods, it shall be ensured that the insertion connection strength is not less than 75% of the minimum breaking force of the rope.
Specifications are changed from countless lessons. I hope everyone can abide by relevant safety standards and specifications. Achieve safe production and safe production. Everyone is responsible for safe production.
