Gantry Cranes: All you need to know
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.
Most construction, manufacturing, material loading, and shipbuilding businesses wouldn’t be able to operate successfully without using cranes.
When it comes to finding the best crane around, many UK businesses only trust cranes supplied by AG Cranes.
AG Cranes has installed cranes across the UK and are helping many firms in a variety of sectors have phenomenally successful, and reliable lifting systems in place.
If you’re interested in learning more about gantry cranes, this article will cover everything you should know about them, and how they could solve your lifting problems.
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 that you’d use to hook up the items(s) you’re lifting and moving.
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-frames which are often referred to as gantries have wheels so they can be used in various locations around a factory or warehouse premises, both inside and out.
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.
With these types of monorail systems only the hoist can travel along the overhead rails.
A Goliath crane is essentially a type of crane that is suspended 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 Gantry cranes to always provide reliable service every time. 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.
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.
