HQ Gaston Mining Pneumatic Hoist is a high-efficiency, high-reliability lifting equipment specially designed for the mining environment. With its unique pneumatic drive system, it can still operate stably in harsh mining environments, ensuring the safety and efficiency of miners' operations. Using advanced pneumatic technology, no electric drive is required, which reduces safety hazards caused by unstable power and reduces maintenance costs. Designed with high-strength alloy chains and a solid lifting frame, it ensures stable operation under heavy load conditions and meets the load-bearing requirements of mining operations. After special dust-proof, waterproof, and anti-corrosion treatment, it can work for a long time in humid, dusty, and highly corrosive mining environments. HQ Gaston mining pneumatic hoists are widely used in various mining operation scenarios, such as coal mining, metal ore extraction, tunnel construction, etc. It can easily cope with complex operating environments and provide strong lifting support for mining production.

The figure shows a typical pneumatic motor torque and power curve at two different air pressures. The motor speed, torque and power decrease as the air pressure decreases. | The figure shows the torque and speed curves of the pneumatic motor under two different air pressures. The speed and torque of the motor decrease as the air pressure decreases. The torque decreases significantly, while the motor speed decreases slightly as the pressure decreases. |
