A Unic URW-706 mini spider crane exercised its 6 tonnes worth of lifting muscle recently to install steelwork to a house in Kew, London.

Special transport was used to lift the crane down onto basement level to install beams to create a steel frame for the building over two days. Mounted on timber billets for extra stability, the mini crane lifted 500kg to a 6 metre height and 1250kg beams to 3.5 metres

The compact but heavy duty Unic URW-706 model was perfect for this job as it could be easily transported to the working site and work with precision around obstacles in the restricted space available.

The larger mini crane models in the Unic range are often used to erect steelwork for private residences and other construction projects. Take a look at a Unic URW-506 spider crane in action on Grand Designs, helping to build a South London contemporary mansion.
