What are the lifting tools commonly used in line construction?
The lifting tools commonly used in line construction mainly include ropes, pulleys, pile anchors, poles, etc. These seemingly inconspicuous small lifting tools bring great convenience to construction work.
1. Lifting Ropes.
The rope is mainly used for lifting and pulling in the line construction. Commonly used are lifting ropes, slings and wire
ropes. The hemp rope used for lifting work is made of high-grade hemp fiber such as sisal, which is resistant to abrasion,
abrasion and corrosion. It is customarily called white brown rope. The hoisting is generally made of high-strength polyester
filament, which has the advantages of high strength, abrasion resistance, oxidation resistance, UV resistance, etc., and has
the advantages of soft texture, non-conductivity, and no corrosion; the wire rope has high strength and small stretchability.
It is reliable to use, because it is also an indispensable tool for the line upright. The wire rope is made of a thin steel wire
immersed oil core. The main function of the rope core is to absorb the lubricating oil to prevent the steel wire from rusting
and reduce the wear during work, and increase the flexibility of the steel wire rope.
2, the pulley blocks.
The pulley is one of the most common tools in line construction. According to the number of rollers, there are single pulleys
and multiple pulleys. According to the function of the pulleys, there are fixed pulleys and movable pulleys. The pulley block
is a combination of a fixed pulley and a movable pulley to achieve a labor-saving effect.
