RailMac 3T Trolley Locomotive

The 3T Trolley Locomotive features a welded – steel frame suspended by leaf springs on grease – bearing seats. It uses a high – reliability electronic speed controller for continuous, stepless speed regulation. Equipped with mechanical brakes acting on all four wheels via brake shoes, a pneumatic sanding system, and spring – buffered bumpers (with the motor also suspended by a spring brace for shock absorption), it supports track gauges of 600, 762, or 900mm. Powered by electric motors (12kW×1, 24kW×1, or 6.5kW×2) with voltages of 250V or 550V, it delivers hourly system traction up to 6.1kN and max traction of 7.36kN. With speed regulation via resistance or IGBT and mechanical braking, this locomotive is well – suited for shunting and short – distance freight tasks in coal, metallurgy, and similar industries, ensuring stable and efficient operation in narrow – gauge 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 3T Trolley Locomotive

• Featuring multi-gauge compatibility (600/762/900 mm tracks) and configurable dimensions (L: 2760–2960 mm × W: 930–1220 mm × H: 1550 mm), its compact build achieves a tight 5.7–6 m turning radius while accommodating variable traction heights (210/320 mm) for versatile deployment.

• Constructed with a welded steel frame, tapered roller bearings, and leaf spring suspension, the locomotive integrates mechanical four-wheel braking with a proactive rail sanding system and dual spring-buffered shock absorbers to ensure operational stability and collision protection.

• Equipped with IGBT or resistance-based stepless speed regulation and a vibration-dampened spring-braced motor suspension, the system minimizes wear while enabling precise speed control (8.1–10.8 km/h) for energy-efficient, smooth operation in confined spaces.
