The Heavy Duty 4 Ton Rail Transfer Trolley Powered by Cable Drum is an efficient and durable material handling vehicle designed for the transportation of heavy loads and components within workshops, factories, and production lines.

This rail-mounted trolley is powered by an industrial-grade cable drum system, providing continuous electrical energy for smooth and uninterrupted operation.
It is widely used for transferring machinery parts, molds, steel structures, tools, and assembly materials between work areas, ensuring safe, precise, and reliable logistics across fixed rail routes.

Compact yet powerful, this 4-ton cable drum transfer trolley offers a cost-effective and low-maintenance alternative to battery-powered carts, making it ideal for medium-duty industrial applications.

Working Principle

The trolley is driven by an electric motor that receives AC power from a cable drum (reel) mounted underneath or beside the frame.

• As the trolley moves along the rail, the cable drum automatically winds or unwinds the power cable.

• The 380V AC power is transmitted through the control box to the motor, providing steady torque and reliable traction.

• The system enables continuous operation over medium-distance rail paths, typically up to 200 meters.

This simple yet robust design ensures high efficiency, strong stability, and long service life.
