Running distance: Unlimited (rail-dependent)
Power supply: 36V rail conduction system

Cable Reel Powered Transfer Trolley (KPJ Type)

The KPJ cable reel-powered transfer trolley is driven by an external power cable that is automatically wound and released by a cable drum as the trolley moves. This ensures a continuous power supply during operation. It is known for its simple structure, low cost, and reliable performance, making it suitable for short to medium-distance transport in industrial workshops, including harsh environments such as high-temperature or explosion-proof areas.

Load capacity: 5–150 tons
Running distance: ≤400 meters
Power supply: Cable reel system

Battery-Powered Transfer Trolley (KPX Type)

The KPX battery-powered transfer trolley uses onboard batteries (such as lead-acid, lithium, or explosion-proof types) to supply power directly to the DC traction motor. It offers high flexibility and is not limited by cables or external power sources, making it suitable for complex track layouts such as S-shaped or curved rails. It is widely used in flexible production environments and special handling conditions requiring mobility and adaptability.

Load capacity: 2–200 tons
Running distance: Unlimited (battery dependent)
Power supply: Onboard rechargeable battery

KPD types are best for long-distance heavy-duty continuous operation, KPJ types are ideal for cost-effective short to medium-distance transfer, and KPX types provide the highest flexibility for complex and variable working conditions.

Rail-Mounted Transfer Trolley vs AGV: Which Is Better?

Rail-mounted transfer trolley (RGV, also called rail-mounted guided vehicle) and AGV (Automated Guided Vehicle) are two core types of automated handling equipment in modern industrial logistics, and “which is better” depends entirely on the actual requirements of your application scenario, business process, and budget. Below is a comparative analysis from multiple dimensions.

Dimension	RGV (Rail Transfer Trolley)	AGV（自动导引车）
Navigation	Fixed rail guidance, no complex control	No track, uses laser/vision/magnetic navigation
Positioning	High stability, ±1–20 mm	±5–20 mm, depends on system
负载能力	Very strong, up to 50+ tons or more	Light to heavy, usually lower overall capacity
灵活性	Fixed route, hard to change	Flexible routes, easy to adjust
System Cost	Lower cost, simpler structure	Higher cost, more complex system
Best Use	Fixed production lines, heavy industry	Flexible production, warehouse logistics

How They Differ in Practice

RGV runs on fixed tracks, making it stable, powerful, and ideal for heavy-load and high-frequency transport in structured production lines. Once installed, the route is fixed, and changes are not easy.

AGV works without tracks and relies on smart navigation systems, allowing it to move freely and adjust routes when production layouts change. It is more suitable for flexible and multi-point logistics.

Selection Guide

RGV is a better fit when operations are stable, routes are fixed, and heavy loads are handled continuously, especially in industries like steel, machinery, and automated production lines.

AGV is more suitable when workflows change frequently, layouts are flexible, or when a factory needs scalable and easily adjustable logistics without infrastructure modifications.

RGV focuses on stability and heavy-duty efficiency, while AGV emphasizes flexibility and intelligent routing. The right choice depends on whether your operation prioritizes fixed efficiency or dynamic adaptability.
