Chainless device for advancing BSL units BISUP – W/1, W/2


The BISUP-W device is designed for reconstruction of BSL units, including scraper conveyors in whole along with the face advance. Its simple construction and pull force can be also utilised in pulling and transporting machines and devices of heavy weights.

The device can be used in underground workings of coal mines, in methane and non-methane fields, in workings of levels ‘a’, ‘b’ or ‘c’ methane explosion hazard and in workings of class A or B coal dust explosion hazard.

BISUP-W device is available in two versions: BISUP-W/1 and BISUP-W/2. They differ in frames used and the way the devices are anchored in a gate road. In addition, each version is made in two variants depending on the hydraulic actuator force.
