Whether it’s floating down canals on special pontoons, to scaling tricky riverbanks or lifting age-old canal locks, GGR’s Unic mini cranes are no rookie when it comes to maintenance projects for the country’s waterways.
Recent construction work at Northgate Locks on the Chester canal, required a large metal 5 tonne capacity gantry to be installed across the water for lifting parts of a new lock gate into place.
GGR’s 2.9 tonne capacity Unic URW-376 mini crane was hired to set-up the gantry as there was no road access to the canal and only a confined space for the crane to work from. The spider crane was more than compact and mobile enough to travel down narrow winding paths and under bridges to get into position next to the canal lock.
To install the metal gantry, GGR operators used the Unic mini crane to lift the frame’s 860kg top beam and 200kg supporting side posts into position ready for it to be erected.
When work on this first lock gate was complete, the mini crane returned to the site to help dismantle the gantry. Once the gantry’s parts where detached from each other, the crane lifted each piece carefully into a sturdy boat on the water which could then carry them down the canal to the site where the next new lock gate was to be built.
