Holmatro’s Advanced Rerailing System set is suitable for railway vehicles with a maximum weight of 181 tons. The two Telescopic Cylinders each have a capacity of 68 tons in the first and 21 tons in the second stage, and a total stroke of 220 and 550 mm to lift the railway vehicle. Both of the cylinders are placed on Traverse Sleds, which are located on the Beam. The Traverse Sleds are connected to each other by two length-adjustable Traverse Struts. Between the Traverse Struts a Traverse Cylinder is located, with a pulling and pushing capacity of 12 tons. This Traverse Cylinder pushes or pulls the Traverse Sleds over the Beam. In this set, two Beams – 2200 mm and 1100 mm – are included. The Beams are connected to each other by a Connection Set.
Mechanical locking is provided by different Stacking Rings. With a fork tool, the Stacking Rings can be placed safely around the plunger of the Telescopic Cylinders. Sled Fill Plates can be placed under the Telescopic Cylinder if necessary, when spaces between the cylinders and the lifting points need to be filled. The Locking Device will prevent the vehicle from sliding during the lifting.
All of the cylinders are operated by a powerful Quattro pump which sends 4 equal flows to 4 independent manually operated control valves. Operating the control valves simultaneously results in guaranteed uniform cylinder stoke speeds during lifting and lowering, regardless the load they’re carrying. Of course, the valves can also be controlled separately to individually operate the cylinders. The actual pressure on each cylinder can be seen on the easy-to-read pressure gauges. The cylinders and the pump are connected to each other by colored Single or Double Extension Hoses measuring 20 meters. The colors of the hoses match with the colors on the pump control panel to help prevent incorrect connections.
