Flame-Retardant & Anti-Static Mining Cable Hooks & Clamps for Underground Systems
The mining cable hook is a product made by new technology, with flame retardant, anti-static, anti-aging, not easy to brittle, impact resistant and other properties, and a load-bearing capacity of not less than 160Kg. The product has a reasonable structure and beautiful appearance , and can be flexibly controlled according to the number of cables installed during use. It saves time and effort when installing, removing, adding and replacing cables, especially when used in underground installation. The industrial mining supply can be reused, which greatly reduces the labor intensity of workers, improves work efficiency, and relatively reduces the overall cost of the project. It is an ideal product for laying cables in coal mines.

Our cable hooks and clamps are engineered specifically for conveyor environments in underground and surface mines. They minimize cable sag and wear, reduce maintenance downtime, and are available in both non-sparking polymer and heavy-duty metal options to match site risk profiles. Polymer hooks provide flame-retardant and anti-static performance for explosive atmospheres, while steel variants deliver very high mechanical strength for heavy-duty rigs.
· Polymer Cable Hooks: Lightweight, non-sparking, anti-static, corrosion-proof, ideal for underground coal mines and areas with strong safety restrictions.
· Steel Cable Hooks: Maximum mechanical strength and durability, recommended for heavy conveyor systems, outdoor installations, and high-load requirements.
We support a wide range of mining safety requirements, including flame-retardant materials, anti-static properties, load-bearing validation, and environmental durability testing. Technical files, test reports, and compliance documentation can be provided for project bidding, engineering review, and safety audits.
Q: Do your cable hooks support hazardous mining environments?
Yes. Flame-retardant, anti-static polymer options are designed for use in areas with combustible dust or strict safety requirements.
Q: What load weight can each hook support?
Polymer hooks typically support up to 160 kg, while steel variants can handle significantly higher loads depending on size and model.
Q: Do you provide technical testing reports?
Yes. Load-bearing tests, flame-retardancy reports, anti-static performance documentation, and material data sheets can be provided for engineering review.
Q: Can these hooks be used on long conveyor systems?
Absolutely. Our hooks are designed to prevent sagging, vibration damage, and cable misalignment along long conveyor lines.
Q: Do you offer custom sizes or OEM labeling?
Yes. Custom colors, dimensions, logo printing, and OEM/ODM services are available for distributors and large-scale mining projects.
Q: How do I choose between polymer and steel cable hooks?
Polymer hooks are flame-retardant, anti-static and non-sparking, ideal for underground coal mines. Steel hooks are better for extremely high loads and outdoor applications.
Q: Can you provide load test reports and certifications?
Yes, we provide load test reports, material data sheets and support for MSHA, IECEx and ATEX compliance based on project requirements.
Q: What is your typical lead time for bulk orders?
Standard products usually require 3–5 weeks. Custom designs and certification requirements may extend production time.

The cable clamp for coal mining machine is made of stamped steel plate as the skeleton and high-density polyethylene through injection molding.
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.
The dustproof seal is a single-acting seal that is installed by extruding the outer diameter. It can effectively prevent dust and dirt from entering, and allow the residual oil to flow back.
The Y-ring is designed as a static seal for the cylinder, which can replace the traditional O-ring/retaining ring combination. Through its unique design and material, the allowable extrusion gap can reach 0.4mm at a pressure of 500bar.
Piston rod seal, double-lip design has better sealing effect, and polyacetal back-up ring is better under pressure.
The piston seal is a two-way seal, used in conjunction with two piston guide rings, and has a two-way sealing effect.
