Mine hydraulic prop I plant specializing in producing mining hydraulic prop, if necessary, call the phone number on the contact picture. Professional manufacturers, creating high-quality mining hydraulic prop. I. Introduction: Mine hydraulic prop is a coal mining face in China is currently the most commonly used constant resistance type support equipment, metal roof beam with it and been widely used in the coal mine general mechanized coal face, or mechanized coal mining face end or boring class support for temporary use, to improve the safety and efficiency of operation have good results. Second, product classification: 1, outside the injection-type hydraulic prop ordinary (Representative model: DW22-300 / 100): cold drawn steel casting, the working fluid is 2% of emulsified oil or neutral underground water, the need for external equipment (emulsion Pump Station) to work to pump station for the power source through the pipe system and the injector gun to achieve lift column. The lowest price, the weight of heavy, cumbersome to use. 2, outside the injection-type hydraulic prop suspension (Representative model: DW22-300 / 100X): cold drawn steel casting, the working fluid is 2% of emulsified oil or neutral underground water, the need for external equipment (emulsion pump station) to work in pumping stations for the power source through the pipe system and the injector gun to achieve lift column. Low price, heavy weight, cumbersome to use, working stroke, causing a range of mining surface height adaptation increases. 3, outside the injection-type hydraulic prop FRP (Representative model: DWB22-300 / 100): the use of lightweight fiberglass cast, the working fluid is 2% of emulsified oil or neutral water underground, the need for external equipment (emulsion pump) to work to pumping stations for the power source through the pipe system and the injector gun to achieve lift column. High prices, lightest, by a single person to handle. 4, within the injection-type (hand type) hydraulic prop (Representative model: DN22-300 / 90): cold drawn steel casting, comes emulsified oil pipe, no other auxiliary equipment, can be achieved only hand lift column descending column. The price is high, heavy weight, easy to use a wide range. 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: general hydraulic prop, within the injection-type (hand rocking) 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, sound and light signals Mine Mine 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, mine Hammer 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 equipment, mining flame-retardant beam pipe mine blast doors: vertical shaft blast doors, blast doors Inclined, refuge chamber door, waterproof airtight doors, fire gates, impact door "integrity through business grand, Seiko casting materials people Aetna" is the idea we have been insisting, ensure product quality, to protect life and property safety of users, the responsibility is extremely heavy!
