KPX Series Battery Transfer Cart

Product Overview

KPX series battery transfer cart energy conversion through industrial-grade lithium-ion battery modules (nominal 48VDC, compliant with IEC 61427) and adopts a bidirectional DC-AC inverter with space vector PWM modulation to regulate the asynchronous traction motor.

This configuration enables continuous torque adaptation across full operational velocity domains (0–100% speed modulation).

The main configuration of the KPX series battery transfer cart: frame, motor, reducer, wheels, battery, charger, control box, etc.

Depending on your actual use, there are different transfer carts for customers to choose from.

We have an experienced team of crane engineers.

We design the right cart system for you, and provide a full range of after-sales services to enable your crane to operate quickly, stably and reliably.

Key Advantages

This crane model is engineered for long service life and low maintenance in demanding industrial environments. Buyers choose it because it is built by the factory itself, with steel structure processed by CNC cutting and automated welding for dimensional accuracy and consistent quality.

• Large starting force and strong overload capacity
• No strict requirements on railway construction
• Unrestricted running distance
• No cables outside the transfer cart, safe and convenient operation
• Adjustable speed.

Main Features

Every KPX Series Battery Transfer Cart leaves the factory complete with the following standard features, verified during final inspection and load testing:

• Wireless remote control and automation: The battery transfer cart adopts wireless remote control operation, so the driver can easily control the vehicle body from a safe distance. In addition, by integrating the automated control system, unmanned driving and intelligent dispatching of transfer carts can be achieved to improve work efficiency.
• Flexibility and adaptability: The transfer cart is not bound by cables and has no limit on the running distance. It can travel freely in a variety of environments and adapt to turns and long-distance operation modes in the transportation link. It is especially suitable for complex tracks such as S-shaped and arc-shaped tracks, and can even achieve 360-degree rotation on the spot.
• Environmental protection and energy saving: The battery transfer cart is driven by a DC motor, which has low pollutant emissions and low noise, which is beneficial to improving the working environment. At the same time, its relatively low energy consumption helps reduce operating costs.
• Safety performance: Fully consider safety factors when designing, and be equipped with multiple safety protection devices such as electronic brakes and anti-collision alarms to ensure the safety of personnel and equipment during driving.
• Efficient carrying capacity: The battery transfer cart has a large carrying capacity and can meet the transportation needs of different occasions. The table is reinforced to adapt to heavy-load working conditions and increase the service life of the equipment.
• Easy maintenance: The battery is stored in a drawer-type box, which is easy to replace. The motor, electrical appliances and other components adopt a modular design, which makes maintenance easy and reduces the equipment failure rate.
• Intelligent and efficient: With intelligent charging function, it can automatically find a charging station when the battery power is low, realizing unattended charging and saving labor costs. It is powered by electricity, has strong power, and travels at a fast speed, which can improve work efficiency.
• Adapt to special environments: For special environments, the battery transfer cart can choose high-temperature-resistant motors and electrical appliances to improve the reliability of the equipment. In flammable and explosive situations, it can also be equipped with high-explosion-proof components to ensure safety performance.

Applications & Working Conditions

The KPX Series Battery Transfer Cart is used across industrial plants, warehouses, steel mills, power stations, ports and logistics centers. It is available with optional lifting attachments such as lifting beams, electromagnets, grabs, C-hooks and coil tongs for special material handling.

Standard models operate in ambient temperatures from -20°C to +50°C. For special environments, we can supply explosion-proof electrics, high-temperature paint systems, dust-proof protection or corrosion-resistant coatings. Tell us your working condition and our engineers will confirm the correct configuration.

Customization Options

We customize span, lifting height, working class, control mode (pendant, wireless remote or cabin), and add frequency conversion speed control, explosion-proof protection or special coatings to suit your environment. Tell us your requirements and our engineers will prepare a tailored proposal.

Standard Supply Scope

Your order includes the complete crane structure, travelling mechanism, hoisting trolley or hoist, electrical control system, safety devices (limit switches, overload limiter, buffers, emergency stop), operation manual and inspection certificates. Optional extras include wireless remote control, frequency inverter, cabin with heater/air conditioner, lighting and special lifting attachments.

Quality Control & Testing

All structural welding is performed by certified welders and inspected before painting. Each crane undergoes no-load and full-load testing on our test bench, including brake test, limit switch verification and electrical safety check. Third-party inspection (SGS or buyer-nominated) is available before shipment.

Packing & Shipping

Cranes are shipped in knockdown form with steel structure, wheels, trolley, electrics and hardware carefully packed to prevent damage during ocean freight. Export packing follows our standard seaworthy specification, with wooden cases for electrics and control panels. Delivery options include FOB, CIF and DDP to your port.

Installation & After-Sales

We offer installation supervision and commissioning by our engineers, or fully turnkey installation by our experienced team. After commissioning we provide operator and maintenance training, a complete documentation package, and 24/7 spare parts and technical support for the lifetime of the crane.
