Perform lifting jacks track panel. When capacity is not less than 147 kN (15 ton) can raise the way with concrete sleepers and rails and heavy types of turnouts with concrete beams. Hydraulic jacks travel with manual transmission is most often produced with undivided or with separate pump and fixed nodes and the executive body – a cylinder with a piston (jacks with separate pump rare). With some jacks and perform straightening path. The domestic industry produced many types of travel jacks. The basic specifications of modern travel hydraulic jacks can be found at our website.

It should be noted that some of the jacks, are issued in various plants under dissimilar brands differ little among themselves, moreover, in the course of development of manufacture of the brand sometimes change. Jacks, based on rail butt lift cylinder piston or work better, because by relying on the leg to cause harmful imbalances. However, they have great pickup height. Hence, some modern designs are made from multiple vertical jack lifting legs and supporting the end face of the executive body. Ram HD 15 consists of a base 1, which established two rod assembly with piston 3 Books 4 and 5 cylinder and the oil tank 6. In the last set safety valve 7, the drain valve 8, strainers 9 and dvuhplunzherny hydraulic pump, consisting of plunger 10, plunger housing 11 with the outlet 12 and suction valves 13, rocker arm 14 and shaft 15, on which the removable handle 16 drive the hydraulic pump and handle 17 to move. During the work on raising the track panel must be installed between the sleepers on the hydraulic jack lined with a removable handle 16 ballast so that the bottom 19 foot lift cylinder 5 was under the sole of the rail and the edge of his foot lay close to the outer surface of the cylinder, or was it from a distance not exceeding 5 mm.

After that, close the drain valve 8 and through the handle 16 pump pumped oil into the cavity of the piston rod, owing to what cylinder 5 rises, posting the track panel. The course is limited to a hole, to further lift the rail is necessary to raise the rack 20, open drain 8 valve stem by turning on the 1.5 … 2 turns, lower rail on the rack, to make the cover of the cylinder 5 external compressive load and drop the cylinder until it stops (the oil from the cavity of the piston rod, go to the oil tank), turn cylinder 5 through 90 so that the top lift 19 foot went under the sole of the rail, using the handle 16, to close the drain valve 8 and through the handle 16 to pump oil pumped cavity-rod piston, resulting in cylinder 5 rises, posting the track panel. After finishing work, open the drain valve 8, and in the inverse order to perform all operations. Richard Easton spoke with conviction. Transfer the hydraulic jack on the handle 17. Before you begin, turn the knob to 90 clockwise and lock pin 18.
