Fire safety rope specifications and standards of use

National standard for safety ropes, standards and specifications for the use of fire safety ropes

The specifications of the fire safety rope are introduced. The national standard sets the rope length of the safety rope to 0.5-3m according to various purposes. For example, if the seat belt is suspended at a high altitude, the rope length is 3m, and the weight of 84kg falls. The impact load can reach 6.5N, and the impact damage is still about one-third of the impact, which can ensure safety. The safety rope is woven from synthetic fibers and is an auxiliary rope for connecting the seat belt. Its function is double protection to ensure safety. The general length is 2m, and there are also 2.5m, 3m, 5m, 10m and 15m. The safety rope of 5m or more is also used as a sling.

1, parallel safety rope

The parallel safety rope is used to move the safety rope horizontally on the steel frame. Smaller elongation, and higher slip rate are required. Generally, steel wire rope is used for injection molding, so that the safety hook can be easily moved on the rope. The inner core of the steel wire is 9.3mm, 11mm, and the outer diameter is 11mm or 13mm after injection molding. Widely used in the installation of steel frames for thermal power generation projects, and the installation and maintenance of steel structures.

2, vertical safety rope

The vertical safety rope is used to protect the rope from moving up and down vertically. It can be used in conjunction with the climbing self-locking device. It can be woven and twisted. It must meet the tensile strength specified by the state. The diameter of the rope is between 16mm and 18mm.

3, fire safety rope

Fire safety ropes are used for high-rise escapes. There are two kinds of weaving and twisting, which are required to be strong and light. The appearance of the rope is 14mm-16mm in diameter, with a buckle and an insurance card lock. The tensile strength reaches the national standard. The length is customized according to user needs. Widely used in modern high-rise, small high-rise buildings.

4, external wall cleaning rope

The external wall cleaning rope is divided into a main rope and a secondary rope. The main rope is used for hanging and cleaning the seat plate, and the auxiliary rope is used as an auxiliary rope to prevent accidental fall. The main rope diameter is 18mm-20mm, and the rope is required to be strong, not loose, and the tensile strength is high. The secondary rope has a diameter of 14mm-18mm and the standard is the same as other safety rope standards.
