Managing director Andrew Pimblett said: “Most crane applications over 10t used to need a double girder crane and it was rare to find a monorail crane lifting over 15t. With our new design we are able to offer single girder crane options up to 25t safe working load for many mainstream applications. This saves material, crane cost, structural costs, weight and extends the crane capability.”
The new Street monorail crane is suitable for processes housed in lightly constructed buildings, where substantial gantries or structural reinforcement would be required for double girder cranes, it said.
A press release added that ‘aerospace manufacturers often fall into this category because of the wide-span bays and hangars used in this industry. The beam and hoist can also be incorporated into a portal or semi-portal crane design with cantilevers extending outside the portal supports.’
Based on a modified reinforced box beam and components from the ZX hoist series, the new cranes give reliability and are easy to customise to client lifting demands, said Street.
Two 15t cranes of the new design have been installed at an extension to Street Crane’s own factory. Bombardier Aerospace in Northern Ireland is also taking advantage of the new technology, where single girder cranes span bays of 64m and allow wings to be hoisted and moved.
