Single Girder Gantry Crane Introduction

Single girder gantry crane is a type of gantry crane with a single girder/beam structure on the top and travels on the crane rails. Usually, it equips with electric wire rope hoist as lifting mechanism, sometimes equips with electric chain hoist, according the working conditions. The electric hoist hangs under the main beam and travels along with it. The main girder of single girder gantry crane is supported by one or two legs which are connected with end beams, so the whole gantry crane system can travel along the crane rails by the end carriages.

As the max lifting capacity of the electric hoist for single girder crane is 20 tons, the lifting capacity of single girder gantry crane is also under 20 tons. But single girder gantry cranes can do most of the work no matter indoor and outdoor, which is why single girder gantry cranes are the most popular gantry cranes.

As you know, for industrial gantry cranes, they are able to move in six directions, left and right, up and down, forward and backward. The electric hoist under the main beam moves in left and right directions, when lifting and lowering, the hook of the hoist move up and down and the whole gantry crane systems move forward and backward.

If the single girder gantry crane travels long distance, it will be equipped with a cable reel. Long travel means long power feeding system, gantry crane cable reel can effectively solve the problem of retracting and releasing the power supply cable.

Sometimes you can see the cantilevers on the left and right of the single girder gantry crane main beam, and sometimes just one on the left or right. The cantilevers length is not included in crane span, if you need to lift loads which are out of the crane rails, a cantilever is a good choice, the electric hoist can travel across the legs. Of course, the cantilever is not infinitely long, it depends on the span of the whole gantry crane.

Comparison of Different Types Single Girder Gantry Crane

Box girder type single girder gantry crane	Truss type single girder gantry crane	L-type single girder gantry crane

FAQ About Single Girder Gantry Crane

Why should we choose a gantry crane?

If your workshop has no column, or you just rent a workshop, we recommend you to choose the gantry crane, which can save the cost of the column and is more convenient to install and disassemble.
When the crane is used outdoors, usually, a gantry crane is more suitable.

Which type of gantry crane is suitable for us?

If the gantry crane is used in an open area and the wind is very strong, you'd better choose a lattice gantry crane (truss type gantry crane).
If the cargo size is large and you need the gantry crane has a cantilever, you'd better choose an L-type gantry crane.

I want to use a gantry crane, but the foundation has already been established. Can I avoid breaking the ground to install the gantry crane?

Yes, once the concrete width of the ground exceeds 20 cm, then there is no need to excavate the ground. Just lay the belt steel plate, bolt it to the concrete floor, and then weld the rails on it.

Can you provide gantry crane spare parts?

Yes, as a gantry crane manufacturer, we supply all spare parts such as motors, hoists, rollers, wheels, grabs, hooks, tracks, walking beams, enclosed busbars, etc.
