DW single hydraulic prop and metal hinged roof beam are used for general mechanized mining face and fully mechanized mining face end or temporary payment roof in coal mine. It is suitable for working face with coal seam dip Angle less than 25°. It can also be used for mining face with dip Angle of 25°--35° when certain measures are taken. This series of single hydraulic prop has good stability and outstanding technical performance advantages. The support height of single mining face is increased from 2.5m to 3.5m, and the coal seam below 3.5m can achieve a full mining height at one time, and the end and leading support can be provided for the working face with a thickness of 4.5m or less.
DW single hydraulic prop is a constant resistance prop, which can be used with various top beams or as the main column. It can be used for general mechanized coal mining or coal mining face support plate, and also for comprehensive mechanized coal mining face end support or other temporary support.
DW single hydraulic prop model significance
For example DW25-250/100:
D- stands for single hydraulic prop
W- is for external injection
25- is the height of the pillar
250- is the rated working resistance of the strut
100- cylinder diameter for support
