[knowledge] the type of safety rope and use it Xiaobian tells you

The safety rope is made of synthetic fiber and is an auxiliary rope for connecting the safety belt. Its function is double protection and ensures safety. The general length of 2 meters, there are 2.5 meters, 3 meters, 5 meters, 10 meters and 15 meters, 5 meters above the safety rope doubles as a sling.

Safety rope type:

1, ordinary safety rope, made of nylon and other materials.

2, live working safety ropes, materials for the silk, moisture silk, Dyneema, DuPont silk.

3, high-strength safety ropes, materials for Dyneema, DuPont, high-strength wire.

4, special safety ropes, such as fire safety rope material for the inner 4.3mm wire rope, outside the preparation of fiberglass; marine corrosion resistant rope material for Dyneema, Paster, high molecular polyethylene; high temperature rope safety rope material is Kevlar, able to -196. C to 204 °C within the long-term normal operation. The shrinkage rate at 150°C is 0, and it does not decompose and melt at a high temperature of 560°C; the heat-shrinkable sleeve is a safety rope, the core is a synthetic fiber rope, the sheath is heat-shrinkable, and it is wear-resistant and waterproof.

Safety rope use method:

1. Parallel safety ropes are used to move the safety rope horizontally on the steel frame. Small elongations are required, and higher slip rates are generally used. Wire ropes are used for injection molding to facilitate easy movement of the safety hooks on the rope. Steel wire core 9.3mm, 11mm, after injection molding outside diameter 11mm or 13mm. It is widely used in the installation of steel frames for thermal power projects and the installation and maintenance of steel structures.

2, vertical safety rope, used for vertical movement of the protective rope. With the use of climbing self-locking device, weaving and twisting can be achieved, must reach the state's tensile strength, the diameter of the rope is between 16mm-18mm.

3, fire safety ropes for escape from high buildings. There are two kinds of weaving and twisting, which require strong, lightweight, appearance and beautiful rope diameter of 14mm-16mm, a buckle, with insurance card lock. Tensile strength reaches national standards. The length is customized according to the user's needs. Widely used in modern high-rise, small high-rise building tenants.

4, external wall cleaning rope, sub-master rope and vice rope. The main rope is used for cleaning and suspending the seat plate, and the auxiliary rope is the auxiliary rope for preventing accidental fall. The main rope diameter is 18mm-20mm, and the rope is required to be strong, not loose, and has high tensile strength. Vice rope diameter 14mm-18mm, the standard is the same as other safety rope standards.
