Hot Sell Roof Beams Steel Roof Beams Mining Supporting Equipment

Introduction of Hot Sell Roof Beams Steel Roof Beams Mining Supporting Equipment
Hinged roof beams can be used with all types of single metal pillar with the composition of metal stents for the horizontal and gently inclined coal mining face supporting roof beams of 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. Hinged roof beams to achieve cantilever support, the coal pillar between the wall and have a 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 necessary equipment hinged roof beams are mainly based on the π-beams made of welded parts.zmwm10
