Mining Permanent Derrick

Headframe modular steel structure, high-strength bolt connection, fast on-site assembly. Optimized load transfer path core structural advantage: hoisting loads transfer sheave platform main truss, inclined support system deliver loads foundation. Main structure bears permanent hoisting system long-term full-load dynamic loads. Resists multi-rope friction hoists large working tension and frequent start-stop impact loads, maintains superior structural stability.

Dedicated to Permanent Hoisting Systems: 

Designed specifically for ground-based multi-rope friction and winding hoisting systems, ensuring long-term operational reliability for mines.

Optimized Structure, Cost-Effective & Efficient: 

Features a large-span inclined support structure with rational force distribution and efficient construction, significantly reducing both construction costs and project duration.

Modular & Rapid Construction: 

Modular steel structure design with high-strength bolted connections for quick on-site assembly.

Scientific & Reliable Load Transmission: 

Hoisting loads travel directly from the sheave platform through the inclined support truss to the foundation, with a clear and stable load-bearing path.

Strong Adaptability to Long-Term Dynamic Loads: 

Effectively withstands sustained tension and start-stop impact loads from multi-rope friction hoists, ensuring reliable full-load long-term operation.

Safe & Stable Structure: 

The inclined support design delivers excellent wind and seismic resistance, ensuring the safety and stability of the hoisting system under complex working conditions.
