A UNIC mini spider crane showed that it has lifting down to a science when it helped with a complicated lifting job at the Cyclotron Research Centre in Louvain-la-Neuve, Belgium.
Invented in 1932, a cyclotron produces very intense high-energy ion beams for nuclear physics, experiments. At this site in Belgium, research and development work is carried out into these particle accelerators and their applications.
A 2.9 tonne capacity UNIC URW-295 mini crane was used to lift and install 20 concrete plates on top of supports in an underground bunker at the Cyclotron Research Centre. Each plate measured in at 6 metres by 2 metres and weighed 200-600kgs.
The mini crane was lifted down into the ground by a mobile crane, which then lifted each of the concrete plates down one at a time for the UNIC spider to install.
The UNIC mini crane was folded up into its stowed position and driven under the overhead supports to make room for the plates to be lifted down into the tight spot. Once the lowered plate was pulled far enough under the supports, the mini crane had enough room to be quickly set up again for lifting the concrete plates into place.
The UNIC mini crane was able to complete this tricky job despite the very confined working area, installing all 20 plates in 3 days.
