Gantry Cranes: Types, Components, Applications & Selection Guide

Gantry cranes are essential industrial lifting solutions widely used for handling heavy materials across various industries. Available in both single girder gantry cranes and double girder gantry cranes configurations, these lifting machines are engineered to deliver optimal performance, safety, and efficiency in material handling operations.

Single girder gantry cranes are designed to carry lighter loads, making them ideal for workshops, small warehouses, and maintenance tasks. Double girder gantry cranes, on the other hand, are built for heavy-duty applications, providing greater lifting capacity, enhanced stability, and superior span. Understanding the differences between these types is crucial for selecting the right crane for your specific application.

What Are Gantry Cranes?

A gantry crane is a type of overhead crane system featuring a bridge supported by legs that move on wheels or rails, as opposed to being suspended from a building structure. Gantry cranes can lift loads ranging from a few hundred pounds to several hundred tons and are available in a variety of shapes, such as the classic “A” frame, as well as “L” and “U” shaped leg designs. The “A” frame is the most common due to its stability and versatility.

All gantry cranes, whether single or double girder, are designed for both light-duty and heavy-duty lifting. The higher the crane’s capacity, the more robust its construction and performance. While double girder cranes generally come at a higher cost, they offer distinct advantages in terms of load size, span, and safety for demanding applications.

Height is another customizable feature, with gantry cranes available in both fixed and adjustable height models to suit different working environments and object sizes.

Construction of Gantry Cranes

Understanding the construction of gantry cranes is key to evaluating their durability, functionality, and suitability for your project. Each gantry crane, regardless of size or capacity, is comprised of three main component categories:

• Mechanical Components – Includes motors, gearboxes, brakes, and moving mechanisms responsible for lifting and travel functions.
• Structural Components – Encompasses the main girder(s), supporting legs, end carriages, and base structure, engineered to withstand operational loads and environmental stresses.
• Electrical Components – Covers the power supply system, control panels, wiring, and safety interlocks facilitating efficient and secure crane operation.

Girders or beams are integral to all gantry crane types, positioned above ground and parallel to the working surface. The design and construction of the frame, legs, and girders differentiate gantry cranes from other overhead lifting equipment like bridge cranes. The legs can feature straight beams, truss structures, or the common A-frame style, providing a range of options for different workspace and load requirements.

Key Components of Gantry Cranes

To maximize performance and ensure safety, it is critical to understand the function and features of each major gantry crane component:

1. Frame

The frame is the fundamental structure, consisting of one or two main girders and supporting legs. The number, length, and size of beams are determined by the weight and dimensions of the loads to be lifted. In semi-gantry cranes, only one leg is present, with the opposite side supported by a building structure or wall. The design often incorporates a rigid leg for stability and a flexible leg to minimize dead weight and adapt to floor irregularities.

2. Trolley

The trolley houses the hoist and moves horizontally along the crane’s girder. Trolley configurations include low headroom, normal headroom, and double girder types. Some advanced trolleys are equipped with adjustable space washers, allowing operators to tailor the trolley width to specific application needs. For safety and smooth operation, wheel bumpers and side guide rollers are often installed to prevent collisions and lateral movement.

3. Hoist

The hoist mechanism is responsible for the vertical lifting and lowering of loads. Gantry cranes may use chain hoists for lighter applications (up to five tons) and wire rope hoists for heavier loads. High-capacity electric wire rope hoists are standard for double girder gantry cranes used in shipyards, steel mills, and construction sites. Choosing the right hoist type impacts lifting speed, operational efficiency, and safety.

4. Power Supply

Power is delivered to the trolley and hoist via a festoon system—a series of cable carriers—or conductor bars. The main panel supplies direct AC or induction AC power, ensuring reliable and consistent performance. For outdoor or mobile gantry cranes, power options may include battery packs or diesel generators for off-grid operations.

5. Controls

Modern gantry cranes offer advanced control options, including push-button pendants, radio remote controls, and even smart automation systems with programmable logic controllers (PLC). These controls enable precise positioning, speed regulation, and enhanced safety through features like overload protection and emergency stops.

Types of Gantry Cranes

There are several types of gantry cranes, each engineered for specific industrial applications and facility layouts. Understanding the differences will help you choose the right gantry crane system for your material handling requirements. Explore the following categories:

Full Gantry Crane

The classic full gantry crane features a bridge, two supporting legs, and a hoist. It travels on wheels, rails, or a track. Full gantry cranes are available in stationary and portable models, offering flexibility for both indoor and outdoor use. Their robust design makes them ideal for shipyards, container terminals, and heavy manufacturing.

Semi-Gantry Crane

Semi-gantry cranes combine the benefits of overhead and gantry cranes by implementing one supporting leg and a wall-mounted I-beam on the opposite side. These cranes are commonly used in workshops, factories, and storage yards with space limitations. Semi-gantry cranes can be installed under existing overhead cranes to maximize material handling efficiency within a single workspace.

Portable Gantry Crane

Portable gantry cranes are lightweight, mobile cranes mounted on casters or rubber wheels. With lifting capacities from 0.5 tons to 5 tons, these cranes can be quickly relocated within a facility for maintenance, assembly, or warehouse operations. Their mobility and ease of setup make them popular for contractors, repair shops, and aerospace applications.
