K13 Railway Ballast Hopper Wagon Ballast Transport Hopper Wagon 60T Pay Load

1. Application

K13 Ballast hopper wagon is a special railway hopper wagon to transport stone slag for laying ballast of new or old railway, or to transport similar grain goods for industrial or mineral factories. It could be loaded from both sides of the railway. When unloading the ballast, the bottom doors could be operated pneumatically or by manual.

2. Main structures

The ballast hopper wagon is mainly composed of wagon body, ballast discharge system, coupler & buffer device, brake device, bogies and etc.

• Wagon body

The wagon body is all welded structure without center beam, consisting of a chassis, side walls, end walls, funnels, and other parts.

• Ballast discharge system:

The unloading system adopts a mechanical transmission device mainly driven by air and supplemented by manual, and the air and manual control can be operated separately. There are six unloading doors in total, two on each side and two in the middle. Air control is achieved through three 254x220 rotary bi-directional air cylinders, with three control valves opening and closing the two sides and the middle bottom door respectively. Manual operation can only control the bottom doors on both sides separately, and there is no manual control for the middle door. Manual control is through gearbox mechanism

• Air brake device

• Hand brake machine

• Coupler & buffer

• Bogie

It adopts K2 type 3 piece casting bogie.
The material of bolster and side frame is B-grade cast steel. The main friction plate of the composite wedge is made of polymer composite material, and the wedge body is made of bainitic ductile iron. The material of the side frame column wear plate is 45 steel, and the sliding groove wear plate is T10. The bogie adopts two-stage stiffness springs. Using a lower center disk plate with a diameter of φ 355mm, the lower center disk is equipped with a conductive center plate wear disc. It installs 197726 compact bearings, RD2 axles, and LM wear type tread HDZB cast steel, HDSA rolled steel wheels. The basic braking device adopts an austenitic ductile iron lining and a combined braking beam. The braking beam frame is connected to the brake shoe support with steel rivets.
