Single hydraulic prop is a new environmentally friendly Support Equipment, both hinged roof beams and the metal used for supporting high-grade conventional mining and use of face support artillery and mechanized mining face roof support ends can also be done individually point support columns or other temporary use.Single hydraulic prop for seam angle is less than 25 degrees - 35 degrees inclined coal seam mining face, the adaptation of the coal seam roof and floor conditions are:
roof pillars behind do not affect the recovery of base should not be too soft, prop depth is not pressed into the floor deterioration of the integrity of the base plate, or should increase the base.
Long working stroke
especially for large height variation face of underground roof.
High supporting strength
Weld-free and adopts suspension technology, high pressure liquid suspension directly act at the top end, reached four-fifths of resistance, force only one-fifth columns,greatly improving supporting stability and load capacity.
Leakage easy to be found
The improved structure avoids the spill within virtual top, take off the top of the prop.Once leaked,will be able to check directly with the naked eye at the underground site.
Easy to maintaince
Simple structure,assembly and disassembly convenient easy to maintain,secure,reliable and so on
The single hydraulic prop is composed of cylinder block, live column and valve.The single hydraulic prop is a single compressible pillar that generates resistance by liquid pressure and realizes lifting and unloading. Single hydraulic props are mainly divided into suspension type, double telescopic suspension type, DN internal injection type and glass reinforced plastic monomer hydraulic prop.
