Semi-Goliath Crane Manufacture
What is a Semi Goliath Crane?
A Semi-Goliath Crane – sometimes referred to as a Semi-Portal Crane – is a overhead traveling crane with one elevated side, and the other side mounted at ground level. The elevated side of the crane is either mounted on rails afficed to the supporting structure of a building, or on a raised gantry. The other side of the crane being mounted on a floor rail. The whole crane can move back and forth on it’s rails. A combined hoist and trolley are attached to the overhead beam. With the hoist traveling along the overhead beam, in combination with the crane structure itself moving, this creates a large – high weight capacity – lift area. Semi-Goliath cranes can either be single-girder or double-girder depending on the weight of the target load.
When should you choose a Semi-Goliath Crane?
Semi-Goliath Cranes are the ideal solution for when a Goliath Crane is required but only one side of the crane is able to have an elevated mounting, or if one side of the crane would be obstructed should a floormouted rail be installed.
[review and amend with Graham] Commonly used on construction sites, ports and harbours, or on projects when the entire crane needs to be relocated to another location.
Single & Double Girder Semi-Goliath Cranes
Decision factors such as weight of your target load, the hook height required, and width span will influence whether you will require a single girder or double girder overhead crane.
Single Girder Overhead Cranes
Single girder overhead travelling cranes generally have a maximum safe working load of up to 25 tonnes. Because of their single girder composition, they generally have a simpler hoist and trolley design which can be easier to install and maintain. A single girder over head crane allows for lighter runway beams either side of the travelling beam due to the lower load that needs to be supported.
Double Girder Overhead Cranes
Double girder overhead travelling cranes can support safe working loads of up to 200 tonnes and hence have a higher duty rating than their single girder counterparts. Double girder overhead cranes also allow you to have a higher hook because the hoist is on top of the beam rather than underneath. Furthermore a double girder crane has a wider span with more width of movement due to it’s composition.

Alternatives to an Semi-Goliath Crane
If you require your crane to be mouted overhead, then perhaps a travelling overhead crane could be your ideal solution.
Overhead Cranes
If you are able to install two floor mounted runway beams, then an entirely floor mounted Golith Crane would be the better solution.
Goliath Cranes
If you do not need your overhead beam to move, and your load only has to move along one axis, then a fixed Gantry Crane could be the best solution.
