China coal supplying DWQ hydraulic props

Introduction of China coal  DWQ hydraulic props

DWQ Titanium alloy Hydraulic props Mining Roof hydraulic Prop will become the ideal replacement products of existing high column series. The product is made of high-titanium alloy steel as raw material, stainless steel as inner cylinder, live column and other key components all use special anti-corrosion treatment, advantages of light weight, high strength, good toughness, impact resistance, corrosion resistance and so on. Water can be used instead of emulsion which saving a lot of cost. Compared with the DZ type prop, the same height and same strength of the hydraulic props weight only 25%,of DZ seriess props.      

Application of DWQ Titanium  Hydraulic  Prop

DWQ Titanium alloy Hydraulic props Mining Roof Prop is suitable for mining and blasting work surface use, especially for the use of large slope of the face. DWQ Titanium alloy  Hydraulic props Mining Roof Prop’s successful development is real realization of the high pillar monomer ultra-light high-strength.

Features of  DWQ Titanium hydraulic props

1, Long working stroke , especially for large height variation face of underground roof.

2, Apply inner bore seal bump- resistance in the underground, with a wide range of use.

3, Never broken. Using friction welding, the weld is not broken.

4, Uses a new sealing device, remove the DZ-type pillar between the piston and plunger leakage point, safe and reliable.

5,Level of support available.

6, High strength, no bend.
