Applicable to underground and ground coal mines containing explosive gas and coal dust: There are a large number of flammable and explosive components such as gas dust in coal mines, and there are many metal equipment and instruments. When the equipment is moved and used, it is very likely to collide with the cable hook, which will produce sparks and lead to explosions. However, the mining cable hook
will not collide with the metal equipment to produce sparks when in use, ensuring the safety of underground coal mines. It is suitable for low-gas mines with an altitude of +1150m-1800m, an ambient temperature of -20℃～+45℃, and an earthquake fortification intensity of VIII.
Major advantage
Corrosion resistance: The flame retardant, corrosion resistant and antistatic materials are evenly distributed in the body of the mining cable hook, and the antistatic and flame retardant properties meet the coal mining industry standards. The humid and harsh environment underground will cause the steel cable hook to corrode and rust, which will increase the friction of the hook, resulting in increased friction, sparks are easily generated during friction, leading to combustion or even explosion. Due to its material characteristics, the mining cable hook can effectively avoid the above safety problems and is more suitable for the flammable and explosive working environment underground.
Lightweight and easy to install: The steel cable hook
is heavy, which will increase the labor intensity of workers and reduce work efficiency during use. The mining cable hook has low density, light weight, low cost, easy transportation and installation, durable and long service life. When used for underground installation, it can not only reduce the labor intensity of workers and improve work efficiency, but also reduce the overall cost of the project.
Anti-aging and strong bearing capacity: The mining cable hook has good anti-aging performance due to the advantages of raw materials. It is not easy to become brittle in a humid environment and has good toughness. It absorbs impact force and can resist repeated impact. The maximum breaking force is not less than 3500N, and it has strong bearing capacity and can withstand loads for a long time. The force is not less than 160kg . When the arc hook bears a load of 50kg, the deflection of the straight rod section is less than 10mm. Compared with other hooks on the market, our company's hooks are slightly heavier and have better bearing capacity.
Stable chemical properties: The mining cable hook is made of PVC material, and the flame retardant, corrosion resistant and antistatic materials are evenly distributed in the body. It has stable chemical properties and is resistant to alkali, alcohol, ether, hydrocarbons, weak acids, lubricants, detergents, water, etc. It is odorless, non-toxic, tasteless, and rust-free. It can be used in a variety of environments without changing the performance of the product itself.
Low hardness: The hardness of the mining cable hook is lower than that of the metal hook, and will not cause damage to the cable when laying the cable.
Anti-static: The arithmetic mean of the surface resistance of the upper and lower surfaces of the mining cable hook is ≤3×108 Ω.
Flame retardant: The average value of the flame burning time of the alcohol burner of the mining cable hook is ≤3.00s, and the maximum value of the flame burning time is ≤10.00s; the average value of the flameless burning time is ≤10.00s, and the maximum value of the flameless burning time is ≤30.00s; the flame extension length after burning is ≤280mm.
The average value of the alcohol lamp with flame burning time of the mining cable hook is ≤6.00s, and the maximum value of the flame burning time is ≤12.00s; the average value of the flameless burning time is ≤20.00s, and the maximum value of the flameless burning time is ≤60.00s; the flame extension length after combustion is ≤250mm.
Wear-resistant and long service life: The mining cable hook has strong wear resistance. During use, it will not be worn due to friction and other problems. It can maintain working performance for a long time. Under normal use conditions, the service life can reach 50 years.
