When prop hydraulic mining hydraulic prop prop prop prop construction of hydraulic works of hydraulic prop price brand quality hydraulic prop Hydraulic prop suitable for coal face retracement support equipment applications, and more especially for props face. Hydraulic prop use can greatly reduce the labor intensity, saving time prop, prop improve efficiency; more due to the column can be operated from the back post, and therefore can greatly improve security. Hydraulic prop requires an external pressure source; primarily by the hydraulic cylinder, valve and traction chains. Technical parameters 1 Rated Rally: 58 KN; 2 liquids rated pressure: 24 MPa; 3 largest telescopic stroke: 480 mm; 4 ends of hook head center distance: 3.3 m; 5 Weight: 22 kg; use: hydraulic prop After the end of the hook in a fixed column, pouring liquid injection port in the holster, pulled the valve to "stretch" position until the piston rod extends to the desired length, the other end of the hydraulic prop sets to be recovered in the column, pulled valve to the "back" position to start pouring gun, retracted telescopic rod, then pull out the pillars, which completed a recovery task.
