Product size (cm) : 43*15*15; Gross weight (including packaging)(kg) : 4.7kg; Hydraulic line extractor Hydraulic signal line tapered pin extractor puller piston pulling inward. The hydraulic pin extractor is a special tool developed for railway signal department, which is convenient to carry and suitable for high altitude and narrow space operation. It is suitable for taking out taper pins of various signal lines in railway signal system. I. Product features: This type of hydraulic pin extractor is compact in structure, light in weight and easy to carry. Simple operation, labor and time saving, easy to use; Wide range of use, no damage to the original parts, the signal line and taper pin taken out, can be used again. Working principle: by oil pump start bar hydraulic pin out around the fulcrum for reciprocating swing continuous pumping hydraulic oil, hydraulic oil driving Lamar pistons, piston front-end via the pull block roof rails, make Lamar cylinder by trapezoidal thread drive device backward, opened-toe stuck by pull signal lines taper pin, pull the signal from an axle hole taper pin. Application scope: The hydraulic pin extractor is suitable for signal line tapered pin size 20, tapered pin big diameter 11.5, thread M8. Four, performance parameters: safety load is 8T, the effective stretch of the pull piston is 20mm, the distance of the pull back (pull out) is 15mm. 1. In use, after the oil cylinder is connected with the puller, tighten the oil cylinder return valve screw clockwise. 2. Hook the taper pin root of signal line with an opening of 11.5mm in the front cone of the puller, and screw the puller trapezoidal thread into the puller to make the piston rod and the top block of the puller tighten up. Shake the start handle of the oil cylinder, and the puller slowly back up to pull the taper pin of signal line out. 3, to retract the lama piston rod, just loosen the oil cylinder return valve screw by counterclockwise direction, the lama piston rod that is under the action of the spring force to shrink the piston rod back, immediately tighten the oil cylinder return valve screw. 4. The red line on the lama piston rod is the limit line of one trip. Therefore, in the rama line of work, as long as the red line on the piston rod is exposed, the trip should be terminated. If you want to continue to pull out, you should start the oil return valve, retract the piston rod, readjust the position between the pull and the top block of the puller, repeat the operation as described above to pull out. 5. Before use, it shall be estimated that the required tension shall not exceed the safe load of the puller 10T, and overloading is strictly prohibited. 6. When used at -5℃ ~ +45℃, (GB443-84) N15 mechanical oil is adopted; When used at -28℃ ~ -5℃, use (GB443-64) synthetic spindle oil, the working oil must be clean.contact supplier or email to admin@b2bgood.com for purchase help
