The single-hinged articulated roof beam is made of high-quality steel and uses a unique hinged structure to connect multiple beams. It has high strength and good toughness. When used with individual hydraulic props, it forms a stable support system. It is widely used in coal mine underground longwall mining faces and roadway support, which can effectively cope with roof pressure, prevent roof fall accidents, and ensure operational safety and smooth mining.

The common specifications for single-hinged articulated roof beams are 1000-1600mm in length, approximately 100mm in width, and 80-100mm in height. The material is special mining steel, and the allowable load reaches 250-400kN. It is connected by hinge pins and used for coal mine underground longwall mining faces and roadway support. It can be used with individual hydraulic props to effectively support the roof, prevent roof fall, and ensure operational safety.
