DW series Individual Hydraulic Prop
DW series Individual Hydraulic Prop
Product Introduction
Hydraulic prop increasingly widely used in the production of its traditional wooden pillars supporting metal friction compared with high recovery, supporting safe and reliable, working resistance constant, setting load is high, the use of flexible benefits. Outer single hydraulic prop can be used alone or in combination with metal hinged roof beams supporting the use, can be used in coal seam dip is less than 25. Stope roof gently inclined to pay, but also for mechanized coal face end support or temporary support available.
