Hand Prop I plant specializing in the production of hand-hydraulic prop, if necessary, call the phone number on the contact picture. Professional manufacturers, creating quality hand-hydraulic prop. Hand hydraulic prop, representatives model DN22-300 / 90, because it uses an internal liquid supply mode, it is also known within the injection-type hydraulic prop. Hand Prop cold drawn steel casting, comes emulsified oil pipe, no other auxiliary equipment, can be achieved only hand lift column descending column. Hand Prop disadvantage is the high price, weight in general, but also its obvious advantages, hand hydraulic prop itself with pump and oil, support is provided with a hand to shake when you can quickly rise column, drop column, drop column does not discharge when the working fluid, can better protect the environment, and easy to use, flexible management, equipment simple. Hand hydraulic prop is a new support environment-friendly equipment, which is equivalent to a jack, both with metal hinged roof beams supporting atmining gun for use face support and mechanized mining face and the roof Supporting tip can also be done alone point column or other temporary support available. Prepare Hand Prop branch located in front of: a, check the emulsion pump mechanical electrical parts is normal, the fuel tank is sufficient emulsion concentration is appropriate, then start emulsion pump, pump ministries to be operating normally, for hydraulic When the force reaches the rated working pressure before the pumping station for the fluid to Face. b, check the pipeline system is intact, the entire joint is leaking, liquid injection gun is working properly. c, the pillar moved to a predetermined location set up branches, first rinse liquid injection gun check valve, liquid injection nozzle, and then inserted into the liquid injection gun with three valves and connected. d, a one-way valve with three valves shall direction towards the old pond or trough under for safety prop.
