china coal0001 DWQ Titanium Alloy Roof Single Hydraulic Acrow Prop Introduction of DWQ Titanium alloy Single Hydraulic Mining Roof Prop DWQ Titanium alloy Single Hydraulic Mining Roof 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 single hydraulic prop weight only 25%,of DZ seriess props. Application of DWQ Titanium alloy Single Hydraulic Mining Roof Prop DWQ Titanium alloy Single Hydraulic 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 Single Hydraulic Mining Roof Propâ??s successful development is real realization of the high pillar monomer ultra-light high-strength. Features of DWQ Titanium alloy Single Hydraulic Mining Roof Prop 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.
