Supporting tools to buy Octagon Mining Machinery 0537-2164096,13295479531 welcome you! DWB28-30 / 100-type pillar, DWB35-30 / 100 FRP hydraulic prop DWB series of light hydraulic prop, glass, steel hydraulic prop is an external solution for constant resistance strut, the company is pioneering and bold innovation, the use of traits made of non-metallic materials involved. The product is light weight, corrosion resistance, easy to operate and so on, the same height and weighs only about 40% of steel pillars, can greatly reduce the operator's labor intensity and improve work efficiency. The main models: DWB35-30 / 100, DWB31.5-30 / 100, DWB28-30 / 100, DWB25-30 / 100, DWB22-30 / 100 DWB28-30 / 100 parameters: maximum height: 2800mm Minimum Height: 2230mm Working Stroke: 570mm Rated working resistance: 30KN Rated working hydraulic: 3.8MPa setting load: 30KN hydraulic cylinder inner diameter: 100mm Weight: 22.5KG Working medium: emulsion, water static pressure of the product as a temporary support equipment, coal mining industries roadway excavation, roadway maintenance is carried out ahead of new equipment, support and temporary shoring. The product is an emulsion or hydrostatic water as the working medium, since the key parts (plunger, cylinder, base, return spring, etc.) using leading anti-corrosion technology, there are certain acid and alkali resistance, suitable for different work environment suitable for working resistance fiberglass ≤30kN temporary support for brittle materials, should be used to avoid the impact, supporting the use of three valves because professional so we do better Octagon Mining Machinery Co., Ltd. mainly produces hydraulic prop, U-shaped cards Lan, the card view, π-beams, metal roof beams, hinged roof beams, hydraulic prop control, lift column Phone: 0537-2164096 Fax: 0537-2280553 Mobile: 13295479531 Manager: Chen QQ: 2462697944
