Product Introduction

Easy-to-operate track unloader

Environmentally friendly power system
These devices are driven by three-phase motors, enhancing operational flexibility. Electric propulsion systems can ensure the lowest maintenance requirements, zero-emission performance and higher reliability. The energy cost of an electric motor is approximately one third of that of a traditional fuel engine.

Ground-to-vehicle transfer system
Coal is directly conveyed from the unloader to the transport truck via a rear-mounted belt, avoiding ground deposition and secondary dust emissions. This method supports sustainable development and reduces environmental pollution.


Leak-proof feed inlet design
The closed feeding port saves space and effectively prevents coal from scattering onto the tracks, ensuring smooth train operation. This innovative design can keep the workplace clean and tidy and reduce the post-operation cleaning work of staff.

Vehicle unloading capacity
The expanded operating range can ensure that the coal on the rail vehicle is completely removed, greatly reducing the reliance on manual cleaning and alleviating the labor pressure.

Intelligent environmental control
This system adopts omnidirectional airflow technology to continuously maintain the exchange of fresh air and uses non-toxic and fluorine-free coolants. Its powerful automated thermal management function can optimize heating and cooling efficiency.

Simplified productivity improvement
By integrating the hydraulic synergy of dual pumps and a coordinated multi-process workflow, this equipment achieves a significantly accelerated unloading speed and outstanding output compared to traditional alternatives.
