‌1. Overview

The pneumatic stopping beam is a kind of device to prevent the running car from being transported in the inclined way of the mine track. The device uses gas power to realize the lifting of the blocking beam, which is labor-saving, smooth, safe and reliable, and effectively prevents the occurrence of running car accidents. The product is exported to mining enterprises all over the country, and is highly praised by users.

2. Main Structure

The product mainly consists of blocking beam, cylinder, air control device and other components. The pneumatic blocking beam is a normally closed blocking device. When a mine car passes through, the reversing valve is operated to make the piston rod of the cylinder contract, and the blocking beam is lifted up by the steel wire rope, and the compressed air enters into the working chamber of the cylinder through the pipeline to make the piston rod extend.

After the mine car passes through, operate the reversing valve, the compressed air enters into the working chamber of the cylinder through the pipe to make the piston rod extend, and the blocking beam falls back to the closed blocking position of the blocking beam under the action of self-weight.

3. Technical Parameters

(1). Lifting height of retaining beam: 2400mm

(2). Rated working air pressure: 0.4～0.8 MPa
