Most of the nowadays widely used shield type and chock shield type mechanized mining brackets have shield beam which is inclined to the rear bottom. The cut roof will fall onto it, thus increasing the weight on the bracket. The easy-to-fall false roof will sometimes exert a backward friction on the top beam, causing the bracket to lean back during moving.

Unlike traditional mechanized mining brackets, our chain haulage top walking roof support has no sharp increase in weight with the increase of mining height. It adopts a brace type structure. The cut roof will directly fall onto the base place, which reduces the weight on the bracket. The stability of this product does not reduce as the inclination or the mining height increases. In addition, this product has lateral moving and locking functions, i.e., the support is locked transversely and longitudinally by cylinders and valves across the whole working face.

This roof support is disassembled for transportation and installed on the spot. It is suitable for supporting steep coal seam with the inclination less than 45 degrees.

This product has been widely adopted in the Vietnamese market. It solves the problems of Vietnamese mines that geological conditions are harsh and roof inclination is large.
