These two UNIC mini cranes looked like the mirror image of each other when they were working together in this restricted space on a bridge. A pair of UNIC URW-295 mini cranes were hired to remove over 600 metres of pipe on a bridge in North Wales.
One spider crane was used to lift a one man work basket down a 1.5 metre gap over the side of a set of railings. The man basket was positioned so personnel could cut the pipework into 5 metre long sections ready to be lifted out. When lifting a person in a man basket, the crane’s capacity is always reduced by 50% for an added safety factor.
The second URW-295 mini crane helped to remove these sections which weighed around 370kg each, lifting them back over to the other side of the railings. The cranesworked to a 4 metre maximum hook height underneath a 6.2 metre high ceiling.
The compact dimensions of the UNIC URW-295 made it suitable for work in this very limited space, GGR’s cranes and operators had just a 3 metre wide area to work in.
UNIC spider cranes can also be used to install pipework, for example when this UNIC URW-095 mini crane worked at a sewage treatment works. GGR also stock a range of lifting accessories for lifting pipes, such as the Easy Pipe Clamp and the Pipe Transporter trolley.
