. Features
. The handover top beam can achieve cantilever support, so that there is a large unsupported space between the coal wall and the pillar, in order to achieve General mechanization of coal mining provides conditions. This product is not only suitable for blast mining working faces, but also is a necessary supporting equipment for roof support of high-end general mining working faces. The handover top beam is mainly made of welded accessories on the basis of profiled beams.

. The .m hinged roof beam can be matched with various types of single pillar metal pillars with hinged roofs to form a metal support for horizontal and gently inclined mining in coal mines. Used for working surface support. Because the roof beam can cantilever support the roof above the working face conveyor, there is a larger space between the coal wall and the pillar, thus providing conditions for new coal mining machinery and bendable conveyors to realize coal mining mechanization
