KPJ Rail Transfer Trolley

 

KPJ Rail Transfer Trolley is a cable-powered track flat car that utilizes an AC 380V cable, which is retracted and released by a cable reel device mounted on the transfer trolley. The cable reel device is positioned below the transfer trolley, directly supplying power through an AC control system to control the starting, stopping, forward, and reverse movements of the machine.

 

       

 

 

The KPJ Rail Transfer Trolley is a classic cable-reel powered rail flat transport vehicle, powered by AC 380V electricity. Equipped with an integrated cable reel installed underneath the trolley, the unit automatically retracts and releases the power cable as the trolley travels back and forth along the track. Electrical power is transmitted via the cable to the onboard AC control system, which precisely governs all operational actions including startup, stopping, forward travel and reverse movement.

Featuring a mature and reliable power supply scheme, this KPJ series trolley boasts a simple structure and convenient routine maintenance. The under-mounted cable reel layout effectively saves deck space and prevents the cable from being extruded or scratched by cargo. The robust heavy-duty frame structure is engineered for stable transportation of workpieces, molds, steel materials and heavy finished goods inside factories.

The complete AC electrical control system delivers steady power output and flexible operation. The cable reel follows the trolley's travelling range synchronously to keep the power cord neatly wound and avoid messy cable stacking on the ground. Suited for short and medium-distance fixed-track transportation tasks, the KPJ rail transfer trolley is a cost-effective material handling solution widely adopted in machinery workshops, metallurgical plants, component processing factories and warehouse transit areas.

Designed for continuous cyclic operation, this transfer trolley can be configured with optional safety accessories such as emergency stop buttons, travel limit switches and anti-collision buffers upon request. It works reliably under conventional indoor industrial environments and stands out as an economical choice for enterprises seeking stable heavy-load rail transportation equipment.

 

 

1. Stable Hysteresis Coupling Cable Reel

- Automatically winds and releases the power cable during operation, maintaining uniform tension to prevent cable damage.

- Ensures long-lasting performance even under continuous heavy-duty use.

2. AC 380V Power Supply for High Efficiency

- Delivers reliable power to the lifting and drive motors, supporting smooth movement and load handling.

- Suitable for demanding industrial environments, including metallurgical and steel plants.

3. Optimized for Medium-Distance Transport

- Maximum effective running distance: up to 200 meters (depending on cable length).

- Ideal for workshops, warehouses, and production lines requiring stable, short-to-medium-range material transfer.

4. Durable & Low-Maintenance Design

- Robust construction for long service life in harsh conditions.

- Reduced cable stress minimizes downtime and maintenance costs.

 

 

1. Suitable for harsh environments, high-temperature settings, and explosive atmospheres;

2. Commonly used in workshops for crossing;

3. Suitable for any load capacity and situations with high usage frequency;

4. If the operational distance exceeds 50 meters, a cable reel assist device needs to be added.

1. How does the KPJ rail transfer trolley obtain power?

The KPJ model adopts AC 380V cable reel power supply. A cable reel fitted beneath the trolley automatically winds and unwinds the power cable during operation. Electric power is delivered through the cable to the AC control system to drive the trolley forward, reverse, start and stop.

2. What are the advantages of under-mounted cable reel design?

The cable reel installed under the trolley maximizes available cargo space on the trolley platform. It reduces risks of cable abrasion, extrusion and trampling compared with externally arranged reels, keeps the working site tidy and lowers cable damage frequency.

3. What travel distance is suitable for the KPJ cable reel transfer trolley?

This model is recommended for short-to-medium distance transportation. Excessive travelling range will require ultra-long cables and increase cable weight and wear. For long-distance transportation schemes, we recommend low-voltage rail powered or battery-powered transfer trolleys as alternatives.

4. Can the control mode of the KPJ transfer trolley be customized?

Yes. Standard configurations include onboard handle control. Remote wireless control, fixed-point automatic stop and speed regulation functions can be customized to match customers' on-site production requirements.

5. What working scenarios fit the KPJ rail transfer trolley?

It is widely used for fixed-track heavy cargo transportation inside factory workshops, processing plants and warehouses, for transporting molds, metal components, steel products and mechanical equipment under normal indoor ambient conditions.

6. Is daily maintenance complicated for the KPJ trolley?

The overall mechanical and electrical structure is mature and straightforward. Daily maintenance mainly focuses on inspecting the cable condition, checking the flexible rotation of the cable reel and lubricating wheel sets. Spare parts are easy to source, bringing low long-term operation costs.
