RailMac 14T Trolley Locomotive

The 14T Trolley Locomotive has a welded – steel frame, suspended by leaf springs or rubber studs on grease – bearing seats. It uses an electronic speed controller, with AC converters turning trolley – line DC into AC to power 3 – phase brushless AC motors (52kW×2 or 45kW×2). Equipped with pneumatic brakes (plus manual stop brake), a sanding system, and spring – buffered bumpers (motor also suspended by spring brace), it supports 600/762/900mm track gauges. With max traction up to 36.4kN and hourly speeds reaching 12.87km/h, it’s ideal for shunting and short – distance freight in coal, metallurgy, etc. Speed regulation modes include Resistance/IGBT or AC Converter, and braking combines mechanical, electric, and air systems. The center – cab design boosts visibility, and its integrated system enables real – time monitoring, ensuring reliable operation in industrial rail scenarios.

The company provides customers with comprehensive life cycle services, from design to power system supply, installation and commissioning, to after-sales service, training, and spare parts supply, as well as troubleshooting and overhaul technical support. This full range of services ensures that customer equipment maintains high reliability and long-term operating efficiency during use.
We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from troubleshooting to overhaul technical support.

Advantages of 14T Trolley Locomotive

• Equipped with dual high-power motors (53kW-2 or 45kW-2) and flexible voltage options (250V/550V), this locomotive delivers 36.4 kN maximum traction at speeds up to 12.87 km/h, engineered for extreme-load industrial transport in mining and tunneling operations.

• Features maintenance-free 3-phase AC motors (eliminating carbon brushes/quick-wear parts) with IGBT or frequency-converter speed regulation, enabling seamless stepless control while reducing operational costs by 45% compared to conventional DC systems

• Specialized center-cab design provides 360° operator visibility, combined with an ultra-adjustable pantograph (2000–3200mm height) and large Φ750mm wheels for stability in confined underground spaces.

• Welded steel frame with leaf spring/rubber suspension and tapered roller bearings supports 14-ton loads, while a 12m turning radius maintains maneuverability despite heavy-duty dimensions (4800×1060-1350×1700mm).

• Integrates pneumatic + mechanical + electric braking with rail sanding technology and spring-buffered motor suspension, ensuring failsafe stopping power and shock absorption in high-impact environments.
