由于厚煤层储量占全国矿产资源近1/2,国内液压支架向大采高和高工作阻力方向发展,目前国内液压支架试验台的结构已满足不了大采高的要求,各大液压支架生产厂家加大了液压支架试验台的投入,介绍一种新型液压支架试验台的提升机构。
As the thick coal seam reserves account for nearly half of the national mineral resources, the domestic hydraulic support to the direction of a large mining height and high resistance to development, the current structure of the hydraulic support test bench can not meet the requirements of large mining height, the major hydraulic support manufacturer Increased investment in the hydraulic support test bed, introduced a new hydraulic support test bench lifting mechanism.
