DFZ hydraulic complex rail

Single cylinder (portable) DFZ series of complex rail track complex DFZ series is the use of the principle of lifting force will force the lifting process improvement for the single working cylinder axle jacking the wheels by the ground (gravel or pillow) and the resistance force generated by rail to complete the traverse and lifting. DFZ Complex track in a hydraulic rescue from the complex is the most secure complex rail. After the wheel off road, in the whole process from the complex rescue, no floating process, the rim along the ground, the guide block and rail movement until re-rail side, the secondary accident does not occur even when the pipeline rupture, so the off road vehicles and staff is the most secure. DFZ type complex rail without locks, on-site installation can be completed within three minutes, when off road wheel for about 300mm, hand pump only 3-5 minutes to complete re-track, motorized pump 1 minute to complete; the more off road when far away, because the hydraulic cylinder for the design principle of double effect, the operator does not need to immediately re-enter the car under continuous operation from the complex. For the entire bogie can be taken off the road two devices simultaneously from the complex rescue. DFZ-6 (modified) portable complex rail by manual pumps, base, auxiliary base, skid plates, ejector and other components. Small size, light weight, rise up fast, simple, safe. DFZ-6 (modified) portable complex rail axle of jacking points, single-cylinder for the three hydraulic cylinders, the maximum traverse of up to 380mm, the lowest operating point is 280mm, maximum lift 370mm, suitable for top lift axle Bus, truck weight ≤90 tons from the complex rescue operations. It applies to maintenance systems vans, vehicle service systems vans, large-scale road maintenance machinery special models, the subway system power-off and other rescue operations from the complex. Single cylinder (portable) DFZ type complex rail through the Chinese Ministry of Railways Product Quality Supervision and Inspection Center. China Railway Publishing House published in 2011, railroad workers job training materials, "rescue machinery driver, co-driver", also for this purpose and Specifications made a presentation models.
