The stability of underground support depends on the reliability of the column cap. The mining nylon column cap uses a minimalist design to ensure safety! With 8 radial ribs for compression resistance, a deep central groove to fit the column, and a thickened wear-resistant bottom layer to withstand immense pressure! From bearing force to fixation, don’t underestimate these numbers! It supports the roof pressure above and stabilizes the column below.

Mining nylon column caps are primarily used to secure and support single hydraulic props. They are typically installed at the base of single hydraulic props to provide stability and support. The design of the nylon column cap ensures that the prop is firmly fixed to the mine’s support structure, preventing slipping or displacement.

Usage parameters of mining nylon column caps:

Total thickness of the column shoe: 55mm

Central groove diameter: 125mm

Depth: 15mm

Bottom thickness: 40mm

Usage characteristics of mining nylon column caps:

1. Lightweight: Nylon weighs only 1/7 of cast iron, making it easy to carry and install, reducing workers' labor intensity. Additionally, the recycling and reuse rate of nylon column shoes (caps) is over 50% higher than that of ordinary metal column shoes.

2. Corrosion resistance: In the long-term damp environment underground, nylon’s corrosion resistance far exceeds that of cast iron and wood. Practical experience shows that the service life of nylon column shoes (caps) is more than three times that of traditional column shoes.

3. Good toughness: Cast iron and wooden column shoes are prone to breakage—cast iron may develop sand holes during casting, while wooden shoes have a soft structure that easily breaks, often making them unsuitable for repeated use.

Mining nylon column caps feature a three-layer reinforced structure, ensuring safe support even under extreme roof pressure.
