The 12.5 tonne overhead crane is used to maintain the plant's generators and the old system used steel chains and pulleys installed more than 30 years ago as part of the Galloway hydroelectric power scheme.
Street CraneXpress fitted the crane with an electrical power unit, a wire rope hoist, and geared cross-travel and long-travel drives. Two geared long-travel motors were also fitted to an adapter plate on the existing end carriages and remote control added to improve operational ergonomics and safety.
The only access to the building housing the crane was via a wooden logging bridge and the project team also had to remove the roof to gain access, due to the size of the personnel door.
"Once we had assessed the project and designed the new gear, we were able to come up with an achievable plan for the refurbishment," recalls Chris Barnes, senior project manager at Street CraneXpress.
"Consideration was given to the manufacture and installation of a new crane, but due to the remote location and restrictions relating to the access of the building, the most practical option was to modify and refurbish the existing equipment," he adds.
The installation project that took a two-man team just two weeks to complete.
