Single girder gantry cranes help businesses improve workflow by reducing manual labor and speeding up load transfers. Whether you're lifting steel coils, machinery parts, or construction materials, these cranes provide a dependable way to move heavy items with less hassle.

This article will walk you through the main types of single girder gantry cranes, their typical uses, and how you can customize them to fit your specific needs. If you're considering buying or upgrading a crane, understanding these basics will help you make a better, more informed choice.

Basics of Single Girder Gantry Cranes

At its core, a single girder gantry crane is a type of overhead crane that uses one main horizontal beam, or girder, to carry the hoist and move loads. The girder is supported by two legs, which usually have wheels that run along ground rails or tracks. This setup allows the crane to move back and forth, carrying loads across an open area without needing a fixed overhead runway.

Key Components of a Single Girder Gantry Crane

• Girder: The single main beam that spans the width of the crane and supports the hoist.
• Legs: Vertical supports attached to the girder, equipped with wheels for movement.
• Hoist: The lifting device mounted on the girder, which can be electric wire rope, chain, or manual.
• Wheels and Rails: Enable the crane to roll along a fixed path for horizontal movement.
• Control System: Usually pendant control or remote control to operate the crane safely.

How Single Girder Gantry Cranes Differ from Double Girder and Other Types

Unlike double girder gantry cranes, which have two parallel girders to support heavier loads and longer spans, single girder cranes use only one girder. This difference makes single girder cranes lighter and less expensive but limits their capacity and span length. For most light to medium tasks, a single girder crane is enough and often more practical.

Another key difference is in the hoist design. On single girder cranes, the hoist usually runs on the lower flange of the girder, which keeps the crane's overall height lower. Double girder cranes allow for bigger hoists that can lift heavier loads and cover wider areas, but at the cost of increased weight and price.

Basic Working Principle

A single girder gantry crane moves loads in three main ways:

• Lifting and lowering: The hoist raises and lowers the load vertically.
• Longitudinal movement: The hoist trolley moves along the girder to position the load anywhere along the crane's span.
• Crane travel: The entire crane moves horizontally along rails on the ground, covering the length of the workspace.

Together, these movements allow precise handling of materials across a large area, with minimal manual effort. The operator controls the crane either by a pendant button or a remote control, ensuring safe and efficient operation.
