Gantries are working in intermittent traffic in a number of industries, including construction. They consist of a bridge that moves along the tracks, as well as a hoist or a winch moving along the crane bridge structure. Gantry, or “portal”, cranes allow efficient and effective close transport within a construction site or industrial plant by moving loads vertically and horizontally.
Types of gantry cranes
Depending on the needs of an individual project, different types of gantry cranes may be used.
1. Full-Gantry Crane
One of the most popular types of gantries which consists of two rigid steel legs which move across rails. This type of crane normally works in a fixed area and vehicles can pass underneath.
2. Semi-Gantry Crane
Most commonly, one leg of a semi-gantry crane moves along a rail and the other leg moves along a fixed system (for example, a wall). It is possible to change the height difference between them.
3. Portable Gantry Crane
A gantry crane that can be moved and assembled in various locations is a perfect option for smaller jobs and lighter loads.
4. Adjustable Gantry Cranes
It can be portable or fixed and comes in variable designs (with different height and span). Width, height or horizontal beam length can become adjusted depending on the job to be done and the load to be carried.
5. Single Girder Gantry Crane
It includes a single girder and a rail only. In most cases, the trolley and hoist are under-hung and they move on the underside of the bridge. It is suitable for limited floor space and low ceilings.
6. Double Girder Gantry Crane
This type of crane consists of two girder beams that form a bridge and is considered to be perfect for heavy-duty jobs. It usually consists of top running trolley and a hoist.
