Hydraulic Support Systems

001

Hydraulic Support Systems

In underground coal mines, hydraulic supports are essential equipment for roof support and miner safety. Hydraulic hoses connect hydraulic pump stations to hydraulic fluid to drive the lifting and movement of the supports. This ensures rapid response to roof pressure changes and guarantees safe underground operations

Shearer Hydraulic Systems

Shearer Hydraulic Systems

Shearers are core equipment in coal mine environment in coal mining, and their hydraulic systems rely on hydraulic hoses to transmit power and control actions of components such as cutting drums and traction devices. Hydraulic hoses can withstand high pressure and frequent mechanical movements, ensuring stable operation of shearers under complex geological conditions.

Conveying

003

Conveying

In coal mine conveying equipment such as belt conveyors and scraper conveyors, hydraulic hoses are used in hydraulic tensioning devices or drive systems to maintain proper belt tension, preventing slippage or misalignment and improving transportation efficiency,

Wear and impact resistance

004

Wear and impact resistance

The harsh underground environment subjects equipment to rock, coal dust, and mechanical impacts. Hydraulic hoses are designed with high -strength reinforcement layers (steel wire braids to spirals) and wear-resistant outer layers, enabling them to withstand abrasion and impact, extend failures and downtime. 

Explosion-Proof and Safety Features

Explosion-Proof and Safety Features

the risk of gas and dust explosions exists in underground mines. Hydraulic hoses are typically made of flame retardant and anti-static materials, complying with coal mine safety standards. They effectively prevent static buildup and fire accidents.
