Trackless Transfer Cart
Rail Transfer Cart
An Electric transfer cart is powered by batteries, commonly lead-acid, maintenance-free gel, or lithium iron phosphate. The batteries power the motor and control system, enabling the battery transfer cart to transport heavy materials within the factory. Lead-acid and gel batteries are low-cost and have mature structures, making them suitable for low-level operation, while lithium batteries are lightweight, have a long lifespan, and support fast charging, making them more suitable for high-frequency, long-term operation scenarios. Users can flexibly choose different battery configurations according to their own usage environment and load requirements.
Electric transfer carts are categorized into various types and configurations, with each type suited to specific lifting requirements and application scenarios. Below are some of the common types:
A rail transfer cart operates along pre-installed steel rails, relying on the guidance provided by steel wheels on fixed tracks to achieve precise and repeatable material transport. Thanks to their high load-carrying capacity, smooth operation, and low long-term maintenance costs, they have become one of the most widely used types of electric trucks in heavy industrial environments.
To accommodate different workshop conditions, electric transfer carts manufacturers offer three primary power supply options for rail-guided transfer carts: low-voltage rail power supply (36V/48V DC), suitable for scenarios requiring continuous, uninterrupted operation, cable reel power supply, suitable for enclosed, fixed-route layouts, and battery power supply, suitable for scenarios that do not require fixed infrastructure and call for flexible deployment. Based on the factory floor plan, track layouts can be configured as straight, L-shaped, or S-shaped curves.
The frame of this transfer car is constructed from welded steel box sections, with dimensions and specifications designed to meet the required load capacity. The selection of the drive motor, gear reducer, and wheel sets is determined based on the load capacity and duty class (M3–M7). Safety devices include buffers, limit switches, and emergency stop buttons, with derailment prevention devices available as an option. Rail-mounted transfer trolleys are the preferred transport solution when the transport route is fixed, the load capacity exceeds 150 tons, and the operating frequency is high. These trolleys are widely used in steel mills, foundries, heavy machinery workshops, and precast concrete facilities for the transfer of steel billets, coils, molds, and large assemblies.

The trackless transfer cart is equipped with polyurethane rubber wheels and requires no tracks to be laid. This highly flexible equipment is particularly suitable for production environments where transport routes need to be frequently changed or where workshop floor space must accommodate multiple functional uses. Operators can control the vehicle using a handheld control panel or a wireless remote control. Depending on the steering configuration, the vehicle fully supports a variety of movement modes, including forward, reverse, lateral shifting, and 360-degree on-the-spot rotation.
As they require no tracks, trackless transfer carts can shuttle between multiple workstations, transition seamlessly between indoor and outdoor environments, and easily traverse workshop aisles, assembly stations, and loading docks. The ground surface on which the trackless transfer carts operate must be hard, level, and possess sufficient load-bearing capacity to support the weight of the cart when fully loaded.
These battery-powered, trackless transfer carts can be equipped with lead-acid, gel, or lithium iron phosphate batteries, depending on shift duration and charging frequency requirements. These transfer vehicles are widely used in mold and tooling manufacturing plants, automotive assembly plants, machining workshops, and any other facilities requiring multi-directional, cross-station material handling without the constraints of fixed track infrastructure.

AGV automated guided vehicle transfer carts operate without human intervention, navigating autonomously along pre-programmed routes or in response to real-time dispatch instructions from the warehouse management system (WMS) and factory control systems. This AGV transfer cart is capable of transporting materials around the clock (24/7) without interruption.
AGV supports a variety of navigation technologies to accommodate different operating conditions. Laser SLAM is suitable for dynamic, flexible path planning in complex environments, magnetic strip navigation is the ideal choice for cost-effective fixed-path deployments, QR code positioning is suitable for high-precision docking scenarios, and vision-based navigation is suitable for facility environments requiring map-free adaptive capabilities. The vehicle is equipped with LiDAR sensors at both the front and rear for obstacle detection, enabling the AGV to automatically slow down and stop, thereby effectively ensuring the safety of personnel and equipment.
AGV transfer vehicles are suitable for factories or warehouses requiring automation, continuous operations, and precise timing. Such as e-commerce logistics centers, automotive parts assembly facilities, electronics manufacturing plants, and pharmaceutical logistics hubs.

RGV rail-guided vehicle transfer cart travels back and forth along dedicated tracks in response to system commands, requiring no manual operation and relying on neither laser nor magnetic navigation technology.
RGV shuttles can be integrated with automated warehouse infrastructure, including automated storage and retrieval systems (AS/RS), conveyor lines, lifts, and AGV transfer stations. When a transport task is triggered by a WMS, MES, or manual command, the RGV rapidly accelerates to the target location, then decelerates precisely to dock with the receiving station. After completing the cargo transfer, it automatically returns to its original position or proceeds to the next task. Its positioning accuracy is as high as ±5 mm.
Typically, users utilize the RGV rail guided vehicle transfer cart to transport pallets, turnover boxes, material bins, and semi-finished components along production lines.

Rail transfer carts operate on fixed rails laid on the ground, offering extremely high load-carrying capacity (up to 500 tons) and enabling precise positioning along fixed routes. In contrast, trackless transport vehicles use rubber or polyurethane wheels, allowing them to move freely on any level surface without the need for rails. Their maximum load capacity is typically slightly lower than that of rail-guided transport vehicles.
Rail transfer carts can be powered by a battery (lead-acid, gel, or lithium-iron-phosphate), a low-voltage rail supply (36V/48V DC conductors embedded in the track), a cable reel, or a tow cable (festoon).
Yes. Our trackless transfer carts and rail transfer carts can be configured for outdoor use with weather-resistant enclosures, sealed drive systems, and appropriate wheel materials.

In the world of material handling and heavy lifting, gantry cranes and bridge cranes are two of the most widely used and popular types of lifting machines. Although both excel in accurately moving large loads, their unique shapes and applications are somewhat different. This article takes a deep dive into the differences between the two types of cranes to help you determine and familiarize yourself with which type is best for your industrial needs. Structural Differences between Bridge Crane and Gantry Crane. When choosing a crane, it’s crucial to understand the structural differences between bridge cranes and gantry cranes. Although both types of cranes handle or move heavy loads, their structures and support mechanisms are very different. The structural differences between bridge cranes and gantry cranes will be explained in detail next: Bridge Crane: Bridge cranes are mainly composed of main beams, end beams, lifting trolleys or electric hoists, hoisting mechanisms, and other structures. Because its two ends are located in the concrete column or metal support, the shape is like a bridge, so it is called an overhead Travelling crane.…
The Lifting Solution Built for Scale Some lifting jobs demand more than a fixed crane can offer. When loads are heavy, spans are wide, and the work happens outdoors or across large open areas, a gantry crane is often the only practical answer. From port container terminals to wind turbine assembly sites, gantry cranes handle material movement at a scale that few other systems can match. Stable structure, high load capacity, and wide operational range make them a core piece of equipment across heavy industry worldwide. This guide covers everything you need to understand about gantry cranes — what they are, how they work, which types exist, what they’re made of, and where each configuration performs best. What Is a Gantry Crane? A gantry crane is a large material handling system built around a portal frame structure. Two vertical support legs carry a horizontal main beam across the working area. This leg-and-beam combination forms a door frame — or gantry — which gives the equipment its name. The entire structure travels along ground-level tracks, with the trolley and hoist moving…
An overhead crane, often known as a bridge crane, is a key industrial lifting system for heavy-load handling in facilities like factories, ports, and warehouses. Available for single girder overhead crane (for lighter loads, 1-32 tons) or double girder overhead crane (for heavier tasks, 5-500 tons) or KBK Light flexible crane (for processing lines, less than 5 tons). It uses overhead structure to save space and avoid ground congestion. Next, this article will delve into the definition, image, application, structure and technical specifications of an overhead crane to help you have an overall understanding of it. What Is An Overhead Crane? An overhead crane is a heavy-duty lifting device installed above work areas (e.g., factories, warehouses) on fixed overhead rails. Unlike mobile cranes, it operates along a fixed path, saving ground space. Its basic components include main girders (the load-bearing structure), end trucks (for longitudinal movement), a hoist trolley (for lateral movement) and a hoisting mechanism (for vertical lifting) and a Control System (for easy and precise operation). An overhead crane’s core structure includes a bridge-frame main girder spanning the…
