The cross-articulated roof beam is made of high-strength steel and has a cross-articulated structure that allows for longitudinal and transverse connection. It can be used with individual hydraulic props to form a stable spatial support system. It is mainly used in complex roof environments in underground coal mines to effectively disperse roof pressure, enhance the integrity of support, reduce the risk of roof accidents, and provide reliable safety protection for mining operations.

The cross-articulated roof beam typically has a length of 1000-1600mm, a width of about 100mm, and a height of 80-100mm. It is made of special mine steel with a bearing capacity of 250-400kN. Multi-directional connection is achieved through cross-articulation points. It is mainly used for support at the intersection of underground coal mine longwall working faces and roadways. It can flexibly adapt to complex roofs and, in conjunction with individual hydraulic props, effectively improve support stability and safety.
