DWB hydraulic prop DWB I plant specializing in the production of hydraulic prop, if necessary, call the phone number on the contact picture. Professional manufacturers, creating high-quality hydraulic prop DWB. DWB hydraulic prop is fiberglass hydraulic prop, on behalf of model: DWB28-30 / 100 external (D W hydraulic prop on behalf of representatives on behalf of fiberglass injection type B, 28 represents the maximum height, 30 representatives bearing 30kn, 100 representatives of the hydraulic cylinder inside diameter.) DWB light hydraulic prop monomer weight, carrying capacity. Lift column fast, convenient prop. Reliable sealing performance. Without pumping and piping systems for the fluid, drop column does not discharge the liquid, keep the environment clean, flexible, easy to manage. FRP hydraulic prop model and technical parameters: DWB22-30 / 100: maximum height of 2.2m, stroke 570mm, supporting force three tons, bore 100mm, weight 21kg DWB25-30 / 100: maximum height of 2.5m, stroke 570mm, supporting force 3 tons, bore 100mm, weight 22kg DWB28-30 / 100: maximum height 2.8m, stroke 570mm, supporting force three tons, bore 100mm, weight 22.5kg DWB31.5-30 / 100: maximum height *m, stroke 570mm, support force 3 tons, bore 100mm, weight 25kg DWB35-30 / 100: maximum height 3.5m, stroke 570mm, supporting force three tons, bore 100mm, weight 27kg DWB38-30 / 100: maximum height 3.8m, stroke 820mm, supporting force 3 tons, bore 100mm, weight 36kg Ji Ning Weitai Mining Equipment Co., Ltd. is specialized in the production of mining machinery and mining explosion-proof electrical professional manufacturers, the products meet explosion-proof standard coal Ann, specific products are: hydraulic prop: ordinary single hydraulic pillar within the injection-type (hand type) hydraulic prop, glass, steel hydraulic prop explosion-proof electrical categories: KTC103 mine communication blocking control device, dust concentration meter, gas measurement, gas sensors, eight belt protection, mine using sound and light signals Mining Machinery: scheduling winch, pneumatic winch, winch throttle, winch, winch mine rake (rake electric), shaft sinking winch (vehicle stability), rake bucket rock machine, drilling machine, bolt rig pneumatic impact drill, hammer Mine Fire Rescue categories: air pressure, self-help system, water supply system self-help, self-help device air pressure, water supply, mining explosion-proof submersible pumps, gel pumps, blocking agent injection pump, portable fire prevention and grouting means mining flame-retardant beam tube mine blast doors: vertical shaft blast doors, blast doors Inclined, refuge chamber door, waterproof airtight doors, fire gates, impact door "integrity through business grand, precision casting materials people Aetna" We have always insisted on the idea that, to ensure product quality and protect the life and property safety of users, the responsibility is extremely heavy!
