For lifting applications where headroom is limited underslung cranes are often a useful way to get more from the available space, letting you complete the task in hand without the need for major structural alterations within your workspace.

Stillages used to handle glass which are delivered to part of Anglian’s Norwich manufacturing plant through a ground level roller shutter door, needed to be transferred to a mezzanine floor for processing. However, as these stillages were to be stacked in bays of up to three high on the upper level this left a very limited amount of space between the top rung of stillages and the building’s ceiling. Pelloby decided an underslung crane system was a suitable solution.

The cranes’ gantry rails, located at either end of its 12000mm girder span, were attached directly to the roof structure. The end carriages of a regular or top running overhead crane would ordinarily sit above these gantry rails, however this underslung design meant that they instead ran below these supports to better use the space available.

The result was that the crane’s single girder beam was able to move along the rail freely, allowing operators to quickly and easily move goods of up to 1.5t safe working loads between the ground level and mezzanine via a radio controlled handset.

Anglian Home Improvement production engineer, Mike Jobling, comments: “We’ve worked with Pelloby in the past on multiple crane installations and so we knew that they had the design capabilities to meet our needs on this job. From sending a representative to site to take measurements to installation and final commissioning, Pelloby kept our requirements in mind throughout the project.”
