A spider crane and a crawler crane from GGR’s range of compact lifting machines were hired to team up together on this project to extend the platforms of a London Overground railway station.
Both a 0.995 tonne capacity UNIC URW-095 mini spider crane and an 8 tonne capacity MCC805 mini telescopic crawler crane were chosen to install the steel beams and columns to construct extensions for the station’s two platforms over two consecutive weekends.
With work on the first platform proving to be a simple installation job, space was limited and access was restricted at the site of the second platform extension so this is where GGR’s compact cranes really showed what they were made of.
The two cranes worked in tandem within a narrow passageway just 4.3 metres wide at one end and 4 metres wide at the other to erect the steelwork. The MCC805 and URW-095 cranes lifted the steel sections simultaneously, 7.5 metre tall columns weighing 2.5 tonnes and 10 metre long horizontal beams weighing 850kg each.
The 2490mm wide MCC805 crawler crane was small enough to gain access through a gate and around the surrounding buildings. As the cranes moved along the platform to lift the steel beams into place, the crawler crane positioned itself around a tight corner to get the last few pieces in.
