Product description: DWB series of light hydraulic prop, glass, steel hydraulic prop for the fluid of constant external resistive pillar, our company is the first and bold innovation, the use made of the characteristics of non-metallic materials involved. The product is light weight, corrosion resistance, easy to operate and so on, about the same height and weighs only 40 percent of steel pillars, can greatly reduce the operator's labor intensity and improve work efficiency. The product is a temporary support equipment, coal industries roadway excavation, roadway maintenance performed advance support and temporary support of the new equipment. The product emulsion or hydrostatic water as the working medium, because of the key components (plunger, cylinder, base, return spring, etc.) using leading anti-corrosion technology, there are certain acid, alkali resistance, suitable for different work brittle materials, should be used to avoid the impact of the environment for working resistance ≤30kN temporary support, fiberglass, complete with three valves. The main model parameters: DWB35-30 / 100, DWB31.5-30 / 100, DWB28-30 / 100, DWB25-30 / 100, DWB22-30 / 100 DWB35-30 / 100 FRP hydraulic prop parameters: maximum height : 3500mm working stroke: 570 / 820mm nominal resistance: 30KN Rated working pressure: 3.8Mpa setting load: 30KN hydraulic cylinder inside diameter: 100mm valve working pressure: 3.8Mpa Weight: 27kg Working medium: emulsion, hydrostatic water DWB31.5 -30/100 FRP hydraulic prop parameters: Maximum height: 3150mm working stroke: 570 / 820mm nominal resistance: 30KN Rated working pressure: 3.8Mpa setting load: 30KN hydraulic cylinder inside diameter: 100mm valve working pressure: 3.8MPa Weight: 25kg Working medium: emulsion, hydrostatic water DWB28-30 / 100 FRP hydraulic prop parameters: Maximum height: 2800mm Minimum height: 2230mm working stroke: 570mm rated working resistance: 30KN Rated working hydraulic pressure: 3.8MPa setting load: 30KN hydraulic cylinder inside diameter: 100mm Weight: 22.5KG Working medium: emulsion, hydrostatic water DWB25-30 / 100 FRP hydraulic prop parameters: Maximum height: 2500mm working stroke: 570 / 820mm nominal resistance: 30KN Rated working pressure: 3.8Mpa setting load: 30KN hydraulic cylinder inside diameter: 100mm valve working pressure: 3.8MPa Weight: 22kg Working medium: emulsion, hydrostatic water DWB22-30 / 100 FRP hydraulic prop parameters: Maximum height: 2240mm working stroke: 570 / 820mm Nominal resistance: 30KN Rated working pressure: 3.8Mpa setting load: 30KN hydraulic cylinder inside diameter: 100mm valve working pressure: 3.8MPa Weight: 21kg Working medium: emulsion, hydrostatic water welcome all over the world, far apart friends come business negotiation bargaining Haobo mining willing to work with you hand in hand to create a better tomorrow.
