Single girder cranes are the most commonly used within the UK material handling industry. They offer a number of advantages over double beam cranes, or pillar jib cranes.
Most importantly they are more economically priced than double girder cranes, and if the factory roof is pitched the ends of the crane beam can be chamfered to gain extra hook height. Our crane designers and 3D modelers can plot the angle of the ends of the crane beam, to match the pitch of your factory roof, to gain you extra hook height.
Single girder, or monorail cranes.
We commonly manufacture single girder cranes up to 10 or 12.5t safe working load. Occasionally a little larger but over 10 tonnes or for much wider span cranes double girder cranes are preferred as they may help stability when lifting loads on the crane hook.
How Are Single Girder Cranes Powered.
In the UK, overhead cranes are usually powered via 3 phase, 415 volts 50 hertz. The power via the customers own motor rated fused isolator is connected to the buzz bar. A towing arm is mounted normally on the end carriages, a set of buzz bar collectors then moves with the crane as it moves back and forth. More on crane buzz bar systems we supply fit are on this link.
