Covered Grain Hopper Wagon Car 1435mm Gauge For Bulk Soybean Corn Wheat

L70 Covered grain hopper car is suitable for Chinese standard gauge railway for the transportation of bulk grains like corn, wheat and soybeans. The hopper car has the features of good sealing, no pollution, and no need package. To maximum expand the capacity, the cross section is designed to be a large tubular shape with 70 tons loading weight and this structure could disperse the force generated by the collision of bulk grain during transportation, so that the grains should not easily hardened and damp. The loading ports are fitting on the top of the hopper wagon and the 4 unloading hopper ports are at the bottom. The doors could be operated easily. The bulk grains could flow out automatically by its own gravity, which is very convenient for loading and unloading. The unloaded grains from the hopper car can be transported to the granary through the conveyor belt under the iron mesh for subsequent processing.

L70 Covered grain hopper car is mainly composed of car body, bogies, brake system and coupler buffer. The car body is all welded steel overall bearing structure. The main section steel and plates are made of Q450NQR1 high-strength weather resistant steel, the side wall is of circular arc cladding structure, the end wall is of plate column structure, the roof is of circular arc plate beam structure, and a full-length loading port is set in the top center. The roof is equipped with nine overturned loading port covers with buffer function, and a pressing mechanism with waterproof function is adopted between the loading port covers. Four hopper unloading ports are arranged at the bottom of the car body, and a pull-out bottom door device is arranged at the bottom of the hopper. The hopper car adopts K6 bogie, 120 type control valve, KZW-A type empty and load vehicle automatic adjustment device and derailment automatic braking device, NSW type hand brake, No.17 coupler in E-grade steel and MT-2 buffer.
