As a leader in UK crane manufacturing, we’re well known for producing overhead, gantry and jib cranes, but we’re always happy to take on bigger design challenges too. That’s exactly what happened when we undertook a major project a few years back with Qualter Hall to provide a heavy duty cantilever crane for Dover Harbour.
Bespoke cantilever crane design
This cantilever crane, which was commissioned to help with the refurbishment of buffers used by roll-on roll-off freight vessels at Dover’s busy harbour, is essentially a double girder electric overhead system which extends over the water’s edge at a height of 27 metres to provide access below.
A robust wire rope hoist unit and winch, which are protected from the elements by a fully enclosed weather cover, are used to support safe working loads of up to 25 tonnes. This weather cover features a walk-in design and internal lights to allow operators to work inside – the electric control panel is also housed within this area.
Both the double girder beam and the hoisting motions are invertor controlled, offer dual speeds and are governed via a radio remote. Take a look at this quick video showing this impressive cantilever crane being tested by our team.
A cantilever crane with safety in mind
Operator safety was a big design consideration when creating this heavy duty cantilever crane. Working at height, over water, and in an outdoor marine environment, the system needed to not only withstand usage in adverse conditions but also ensure those using the system were able to work as safely and efficiently as possible.
The cantilever crane’s crab unit is a prime example of the design steps Pelloby undertook to overcome this challenge, as it is completely enclosed by a hand rail with a self-return gate to allow easy access to all points, rope anchors and limits – while minimising the potential for accidents and guaranteeing those operating the system are protected.
The finalised cantilever crane design also included additional safety features such as a parking latch, specialised maintenance walkways and rail enclosed fixed ladders.
