I Beam Bending Machine - YG Company Professional

I beam bending machine is a kind of mechanical equipment for bending steel beam.Steel beam bending equipment is mainly used for arched rounding and angle bending of H steel,U steel,round steel,rail steel,and other section steels.So it is also called H beam bending machine,U steel bender,section bending machine.Beam bending machines are commonly used for supporting steel bendingOptimization for U-Shaped Steel Support in Deep Tunnels With the effects of high geostress and intensive dynamic disturbances in deep mining,the stability and safety of tunnels are seriously affected.The optimization for U-shaped steel support is of vital significance and can solve the problems of cost reduction and tunnel instability.Based on the perturbation equation,a coupled formula for U-shaped steel and the surrounding rock mass was Roadheaders for Tunneling,Excavation,and more Antraquip roadheaders are typically used for tunneling (road,railroad,water,sewer) or in the mining industry.For the excavation of shafts,Antraquip suggests its roadheader based shaft sinking equipment provided the UCS of the material to be excavated does not exceed 8,000 psi.
