YQ-4C hydraulic Tracking lifting machine is a special machine used for starting operation of 1435mm gauge 43-75 kg/m rail line (when used for 75 kg/m rail line, it needs to be replaced with corresponding rail hook), and operates under the condition of blocking the line. The machine is equipped with running gear and can be carried out on rail. There are insulation devices in the hook rail, the running and the lower road, which do not affect the line signal during operation. Equipped with random lower frame, the starting Lane will not enter the boundary after the lower road.
The general structure of YQ-4C hydraulic starting machine adopts portal structure. The starting cylinder fulcrum is on the inner side of the track and the rail jaw is hooked on the inner side of the rail. The two sides of the frame are equipped with wheel type running device, and both sides of the frame are provided with a lower road device. YQ-4C hydraulic starting machine is mainly composed of frame, starting mechanism, rail hooking mechanism, running mechanism, power device, hydraulic control system and other components, and is equipped with undercarriage. YQ-4C hydraulic starting machine is powered by a small gasoline engine and driven by a belt drive hydraulic pump to supply oil. The oil is transported to various working cylinders by controlling a multi-way reversing valve to drive the working mechanism to complete the actions of rail hooking, starting and running.
Engine rated power: 8.6 kW
