  1. Detailed information

 The  unloader technology  of  WYG70 hydraulic track type swing arm grab adopts   the upper part of WYS50 car unloader, which is a mature product of Bada, and the lower part  uses the traveling part of the chain bucket gantry car unloader. The traveling motor part is driven by a mature hydraulic motor.In fact, the walking chassis is replaced for the tire unloader, which is suitable for the reloading operation on the railway line. Its reliability is very stable. The hydraulic system pumps, valves, seals  adopts  well-known products  at home and abroad ; The control valve adopts the original international famous brand. In order to check the pressure in the hydraulic system, there is also a hydraulic detection point; High pressure oil pipe is connected reliably, arranged reasonably, and replaced conveniently. Oil leakage is strictly prohibited; The hydraulic oil pipe and cable are routed separately, and protective devices are installed at the exposed pipeline parts that are easy to collide with each other.

The equipment has good stability and safety in joint operation. It only takes 6-10 minutes  to unload 70 tons of coal, sand and gravel , and the remaining materials can be cleaned simply . When unloading other materials, it only needs to replace the grab.Based on the rail surface ,the maximum operating range is 8 meters, the minimum operating height is - 1 meters, and the maximum operating height is 8 meters . The power is electric drive, which is driven by 4 motors. One main power, two for walking, and one for air cooling.
