Cable Hook

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.
