Summary of DJB1200 Handover Roof Beams

Product Summary: DJB1200handover roof beams' purpose is to deal with various types of metal pillar with hinged lid (single prop or friction pillar) composed of metal stents for the for coal mining face supporting.in the horizontal and gently inclined working surface to keep a high-intensity beam energy because of this top coal face cantilever retaining wall in front Road transport aircraft above the roof, walls and pillars of coal between a larger space without support, it is using the new flexible transport and mining machinery, mining general mechanization to achieve the conditions for general mining, and new high-end luxury mining technology necessary equipment. Cantilever roof beams to achieve the transfer of support, the coal pillar between the wall and the larger space without support for the realization of mechanization of coal mining generally provided the conditions.

The product is only suitable for blasting mining face, but also the high-grade mining face roof support equipment necessary for the transfer of the top beam is mainly based on the π-beams made of welded parts.
