The crane trolley is mounted on the main girder and is responsible for supporting the lifting mechanism. It moves horizontally along the main girder rails, thereby enabling the lateral movement and lifting of heavy loads. This equipment features a compact design and can be equipped with various types of hoisting mechanisms.
A crane trolley is the load-carrying mobile component in an overhead crane or gantry crane system. The crane travel trolley runs along the rails on the main girder and supports the hoisting mechanism responsible for lifting and lowering loads. By moving the trolley horizontally, the load can be positioned at a specified location. This dual-axis motion mode enables load positioning capabilities in three-dimensional space.
Each crane electric trolley features welded steel frame construction with precision-machined wheel assemblies. Hardened steel wheels distribute loads evenly while sealed bearing assemblies reduce maintenance. Electric crane lifting trolley models integrate VFD technology for smooth acceleration and precise speed control. Safety systems include overload protection (90% warning, 110% shutdown), emergency stop functionality, and anti-collision systems.
Crane trolleys come in various types, including European crane electric trolleys, hoist crane trolleys, and winch crane trolleys. Each crane lifting trolley type has distinct application scenarios and structural designs. The following section provides a detailed overview of each type of crane travel trolley.
Hoist Crane Trolley
European Crane Trolley
Winch Crane Trolley
Hoist Crane Trolley: A hoist crane trolley is a system that integrates an electric hoist with a traveling mechanism. It lifts heavy loads using the electric hoist while simultaneously traversing laterally along the main beam rail via the trolley, thereby facilitating the spatial handling of materials. This system features a simple structure, low cost, and ease of installation and maintenance. Typically, the rated lifting capacity range of a crane trolley is 5 to 32 tons.
European electric Crane Trolley: European crane lifting trolleys minimize the distance between hook and bridge girder, maximizing available lifting height in facilities with limited vertical clearance. The European crane trolley is equipped for use on the QDXX type double-girder overhead crane. This European crane trolley features a lightweight design and high precision, making it suitable for medium to heavy loads. Its lifting capacity typically ranges from 10 to 50 tons. Furthermore, specially customized models can achieve a maximum lifting capacity of up to 80 tons.
Winch Crane Trolley: Winch crane electric trolleys are specifically designed for use in extreme operating conditions. They feature a reinforced structure, oversized components, and higher safety margins. With load capacities up to 200 tons, they are suitable for use in steel mills, foundries, and heavy manufacturing facilities.
The crane electric trolley primarily consists of a lifting mechanism, a trolley frame, wheel assemblies, a braking device, and an electrical control system. Below, I will explain each component and its function.

A crane travel trolley is the movable component of a crane that travels along the bridge main girder rails, supporting the hoisting mechanism. It moves horizontally across the bridge while the hoist provides vertical motion, enabling precise three-dimensional load positioning.
Daily visual inspections, monthly lubrication, quarterly electrical checks, and annual comprehensive examination, including load testing. Typical maintenance costs run 2-3% of the purchase price annually.
When selecting a capacity, users are advised to choose a rating that is 25% to 50% higher than the maximum lifting weight. For occasional lifting operations with known loads, a 25% safety margin is sufficient. In production environments where loads vary significantly, a 50% margin is required to accommodate dynamic loads.

A gantry crane is a large-duty material lifting equipment. It is popularly used in construction sites, port terminals, factories, open-air storage yards, and shipyards. This industrial lifting equipment is assembled from a variety of key parts, which also facilitates its transportation from production to the use of the site and the later maintenance and repair. This article will help you understand the core gantry crane parts, analyze their structural characteristics and functional principles, to help you gain a more comprehensive understanding of this heavy-duty crane system and its components. What Are The Parts Of A Gantry Crane? A gantry crane comprises multiple key parts, including the main girder, support legs, tracks, travel mechanism, hoist mechanism, and electrical system. Other important components include the controller or operator’s cab, pulleys, brakes, and various safety devices. These components work together to move cargo from point A to point B. The following will introduce you to the functional description of the gantry crane parts.

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…
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.…
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…
