Gantry Cranes: All you need to know about them.
Gantry Cranes serve a variety of different purposes and are used in many industries across the world. These machines are necessary for lifting and moving heavy loads that otherwise couldn’t be handled.

Read on.
What Is A Gantry Crane and What Does It Do?
So, the basics. A gantry is a steel structure that typically spans across an area of a workshop, factory or loading bay. It can be situated more or less anywhere with enough room/head height and a solid base to work from.
The crane part is the bridge beam that travels along the steel gantry structure and has and electric hoist. The hoist uses it’s hook to lift the items(s) you’re lifting or moving, allowing safe and controlled lifting.
They range in size and weightlifting ability. They can be used for relatively small things like a mechanic lifting an engine out of a car, to factory machinery that weighs up to 30 tons.
Overhead gantry cranes run on rails that are stich welded to the centre of the gantry track. The crane and hoist can operate anywhere within the envelope of the gantry system. A-frame cranes which are often referred to as gantries have wheels so they can be pushed to various locations around a factory or warehouse, hence are fairly flexible.
A variation of these systems would be a monorail crane, this type of crane could be permanently fixed on steel work in the ceiling of the factory or mounted on free standing columns. (read more about “Which Crane is Suitable for a Factory?)
With these types of monorail systems only the hoist can travel along the overhead rails.
Types of cranes.
A Goliath crane is essentially a type of crane that runs on legs (like an a-Frame) and operates on floor-mounted rails. This creates a perfect lifting and handling solution that can be used in a variety of industries.
This allows the Goliath cranes to always provide pick and place within the hook envelope. You may also hear people refer to Gantry Cranes as Goliath cranes or portal cranes. You will be able to distinguish a Gantry because they always have a steel frame with a horizontal beam (or two), and upright columns for support. These columns are bolted to the floor, regardless of the cranes height.
However, many people often get the Gantry Cranes confused with overhead cranes. An overhead crane is a system in which a horizontal crane beam is traveling along the supported Gantry steelwork.
The Gantry crane is supported by legs that either ride on rails that are implanted on the ground or travel on wheels. While they are useful in a variety of industries, they are typically used outdoors or below an existing overhead crane system.
Gantry Crane Types
There are three types of Gantry cranes in the UK, which we cover in detail below.
· Standard Gantry Cranes
The standard (but always trusted) model of the Gantry crane is one of the most popular sellers in the UK. This make has either a fixed or traveling Gantry frame that will have one horizontal beam and two upright columns.
· Semi-Gantry Cranes
Many businesses prefer semi-gantry models. These are systems that use a combination of floor-mounted rails and elevated rails.
· A-Frame Gantry Cranes
These are fixed and portable crane systems that are capable of handling both light and heavier loads. They are one of the more versatile types of cranes available.
What Is A Gantry Crane’s Lifting Capability?
Gantry Cranes often come with full service and support packages to ensure they operate safely. These cranes can handle nearly any lifting height without having to worry about safety. When it comes to their maximum lifting capacity, it will depend on which type of Gantry Crane you are operating.
A Gantry Crane that has single girder capacities can manage up to 25 tons (55115.6 lbs), but a Gantry Crane with double girder capacities can handle up to 200 tons (which is a whopping 440.925 lbs).
One of these cranes could carry the weight of an elephant, an off-road vehicle, and more heavyweights all at the same time. No wonder so many industries rely on them.
