RailMac 30T Trolley Locomotive

The 30T Trolley Locomotive features a welded – steel frame suspended by leaf springs or rubber studs on grease – bearing seats. It uses an electronic speed controller, with AC converters transforming trolley – line DC to AC to drive 3 – phase brushless AC motors (85kW×2 or 110kW×2). Equipped with pneumatic brakes (plus manual stop brake), a sanding system, and spring – buffered bumpers (motor also suspended by spring brace), it supports 762/900mm track gauges. With max traction up to 78kN and hourly speeds reaching 13.2km/h, it excels in 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. Its integrated system enables real – time monitoring, ensuring reliable heavy – duty 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.

Advantages of 30T Trolley Locomotive

• Engineered with dual high-torque motors (85kW-2 or 110kW-2) on a 550V system, this locomotive delivers industry-leading traction up to 78 kN at speeds of 12.7–13.2 km/h, enabling efficient transport of extreme loads in mining, steel plants, and heavy industrial operations.

• Equipped with Japanese-engineered 3-phase AC motors (eliminating carbon brushes and quick-wear parts), coupled with IGBT or frequency-converter speed regulation, ensuring maintenance intervals 50% longer than conventional DC systems while enabling seamless stepless control.

• Built with a welded steel frame, tapered roller bearings, and leaf spring/rubber suspension to support 30-ton loads, while dual spring-buffered motor mounts and shock absorbers ensure operational stability and component protection in high-impact environments.

• Integrates pneumatic + electric + mechanical braking with proactive rail sanding technology, delivering failsafe stopping power on steep gradients, while electronic speed controllers guarantee precision in heavy-load operations.
