Every overhead and gantry crane relies on a dependable traveling unit — the crane end carriage. Our box-type welded frames, forged and precision-machined wheels, and matched drive systems keep your crane tracking straight along the runway rail, cycle after cycle.
A crane end carriage is a traveling mechanism mounted beneath the main girder of a bridge crane or gantry crane. This mechanism supports the entire crane structure and travels along the rails. Its rigid box-section frame, wheels, and drive system work together to enable the entire unit to move longitudinally. Featuring a modular design, this product can be bolted directly onto single- or double-girder crane structures without complex on-site modifications. The VOITTO engineering team can provide customized solutions based on the user’s operational requirements.
A crane end carriage, sometimes called a crane end truck or crane travel unit, is the structural component fixed at each end of a crane’s main girder that connects the girder to the crane’s wheels. It supports the girder’s weight, transmits the combined load of the girder and lifted cargo to the runway rail or ground track, and drives the crane along that track through a motor-and-wheel assembly.
In an overhead crane, two end carriages bolt or weld onto the ends of the main girder, forming a bridge-like frame that spans the runway beams on either side of the workshop. In a gantry crane, the end carriage instead connects to the crane’s legs and travels on rails at ground level or on a paved surface. Because the end carriage carries the full traveling load, its rigidity, wheel alignment, and drive configuration directly determine how smoothly and safely the whole crane moves along the runway.
The specifications of crane end beams vary depending on the crane type, structure, and operating environment. The table below compares the four most common configurations offered by VOITTO, ranging from standard bridge crane end beams to heavy-duty end beams designed and manufactured specifically for continuous operation in ports and steel mills.
| Type | Application | Features |
|---|---|---|
| Overhead Crane End Carriage | Single girder overhead crane; double girder overhead crane | Smooth runway traveling; compact structure |
| Gantry Crane End Carriage | Single girder gantry crane; double girder gantry crane | High load capacity; outdoor operation |
| European Standard End Carriage | Overhead and gantry cranes requiring FEM-compliant components | Modular design; low noise; high precision |
| Heavy Duty Crane End Carriage | Steel plants; ports; heavy industry | High wheel load capacity; long service life |
The crane end carriage consists primarily of the main frame, wheels, drive system, and buffer system components. These components work together to enable the equipment to move longitudinally.

Rigid Box-Type Structure: The box-type welded frame structure distributes operational loads evenly across the crane end beams, thereby reducing localized stress.
Precision-Machined Wheels: The forged steel wheels are manufactured using high-precision machining processes to ensure uniform contact between the wheel face and the full width of the rail.
Smooth and Stable Operation: Precise wheel alignment and a balanced drive layout ensure that the end beams travel in a straight line along the rails, minimizing deviation and lateral rail contact.
Modular Design and Easy Installation: The end beams are directly bolted to the main girder, eliminating the need for extensive on-site welding during installation and subsequent replacement. This modular design shortens the commissioning cycle and allows for the replacement of damaged end beams without dismantling the entire crane.
Low Maintenance Costs: Sealed bearings, wear-resistant wheel materials, and user-friendly connection point designs reduce the frequency and cost of routine maintenance.
Customization: VOITTO Crane offers customized solutions. This customized design ensures that wheel load, drive power, and structural dimensions are perfectly matched to actual operating conditions.
VOITTO Crane manufactures crane end carriages and complete overhead and gantry crane systems for industrial buyers across Europe, the Middle East, Southeast Asia, Africa, and South America. VOITTO engineers design each end carriage to meet project-specific capacity, span, and duty requirements rather than pulling it from a generic catalog.
With export experience across multiple regions, our team supports overseas customers through technical documentation, installation guidance, and after-sales spare parts supply for crane end carriages and related components. Please feel free to contact us for crane solutions.

A crane end carriage is the traveling unit mounted at each end of a crane’s main girder. It houses the wheels, drive system, and connection points that support the girder and move the crane along the runway rail or ground track.
Crane end carriage and crane end truck describe the same component. Both terms refer to the structural unit that connects the main girder to the crane wheels and drives the crane’s traveling motion along the rail.
When selecting a crane end girder, users must comprehensively consider the crane’s rated lifting capacity, span, duty class, travel speed, and operating environment. In addition, inspecting the condition of the rails is crucial, as the wheel alignment tolerance depends on the existing rail gauge and the condition of the rail surface.

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…

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.…
