Most construction workers will have heard of gantry cranes and used them at many points in their careers. Often when somebody uses the term ‘gantry crane’, they’re actually referring to a bridge crane but there are key differences between the two.
What is a Gantry Crane?
A gantry crane is used in construction in the material handling industry. It’s a type of overhead crane that is used below a bridge crane system.
Gantry cranes don’t need to be anchored to a building’s support structure and can stand alone. Because of this, they are more flexible and versatile than fixed crane systems.
A gantry crane has strong, freestanding ‘legs’ that move along the ground via rails or wheels to enable construction workers to transfer materials from one place to another.
Where Can Gantry Cranes Be Used?
There are a variety of industries that might need a fixed or portable gantry crane hire service. Most commonly, you will find gantry cranes on construction sites but they can also be used in scrap yards, manufacturing warehouses, and in the steel industry.
What are the Different Types of Gantry Cranes?
There are a few different kinds of gantry cranes, each of which have unique functions and applications.
- Full gantry cranes are the most common type of crane system. They have two legs that move along a straight rail. Other types of motorized equipment can move underneath the crane, such as fork lifts or trucks.
- Semi-gantry cranes have a single leg that moves along a rail or uses a set of wheels. One side of the crane is attached to the side of a building structure.
- Portable gantry cranes are much smaller than traditional options. They can save space and are easier to transport from one site to another.
- Adjustable gantry cranes can reach a variety of heights and are highly versatile.
What are the Uses of Gantry Cranes?
The most common use of full gantry cranes and semi-gantry cranes is for lifting and moving heavy materials. Smaller gantry cranes are better for moving parts or materials around a warehouse or manufacturing facilities that don’t deal with extremely heavy materials.
Gantry cranes can also be used in building work where concrete and cement are being used. They are ideal when for construction projects where additional equipment is required, such as fork lifts, trolleys, carts, and trucks.
If materials need to be moved from one place to another across a far distance, portable gantry cranes are ideal. The gantry can be moved around and provides the necessary flexibility to complete the work.
Are Gantry Cranes Dangerous?
Using any type of crane carries a health and safety risk. Being struck by the moving arm of a crane or falling materials can cause serious injuries or even death.
Accidents and injuries can be prevented with proper use of the gantry crane. Every worker who operates the gantry crane in any location must be qualified and trained to do so.
