Main feature
1、Two column shield type hydraulic support, support to roof compatible; The top-beam was relatively short, reduces has supported the number of times repeatedly to the roof, maintained as far as possible the roof the integrity.
2、Uses the overall top-beam, enhanced front end greatly the top-beam bearing capacity, reduces the roof to the coal wall´s pressure, prevents the cave-in of sides, the roof failure effectively.
3、The top-beam with shields the Liang hinge place to use the round arc closing board structure, guaranteed that does not reveal in the operating altitude scope goes against.
