K13BK Limestone Hopper Wagon

RailMac K13BK Limestone Hopper Wagon

The K13BK Limestone Hopper Wagon is a specialized 4-axle rail vehicle engineered for efficient bulk transportation of limestone and similar granular materials. With a nominal loading capacity of 60 t and a dedicated loading volume of 41 m³, it is optimized for the specific density characteristics of limestone, ensuring precise cargo matching and minimal space waste. Its ultra-light tare weight of only 21.5 t yields an impressive payload-to-weight coefficient of 0.358, a benchmark in its class, significantly enhancing economic efficiency.
As part of SinoMac, RailMac provides full life‑cycle services for the K13BK Limestone Hopper Wagon, including design, system supply, installation, commissioning, after‑sales training, spare parts supply, troubleshooting and overhaul support, ensuring stable and efficient performance throughout its service life.

Advantages of K13BK Limestone Hopper Wagon

The wagon body adopts an all-steel welded structure design; the main bearing components are manufactured with the O8CuPVXt or O9CuPTiRE-A high strength low alloy steel with atmospheric corrosion resistance.
The underframe is composed of traction beam, side beam, sleeper beam, end beam, small cross beam, railing, bracket, and steel floor; The traction beam is composed of two 310 Z-shaped steel; The sleeper beam is a steel plate welded box structure.
An observation hole is set on the first end wall for the convenience to observe material loading and unloading progress.
There are four bottom door discharge ports on both sides of the wagon body. The opening and closing of each bottom door is controlled by a 356 x 280 bidirectional air cylinder and a reducer respectively. The structure design of the transmission device is exquisite and simple. The front and rear supports of the upper transmission shaft adopt the automatic self-aligning rolling bearing, which can avoid the energy waste caused by the non concentric front and rear supports.
