Lifting of a building maintenance unit using ALE’s Lightweight Service Crane, UK
ALE has successfully lifted a building maintenance unit (BMU) onto a 124m high roof in London, UK. This is the first time the Lightweight Service Crane has been utilised.
The BMU was comprised of components, weighing between 1t – 3.5t.
ALE was tasked with lifting the BMU from street level to the top of a high-rise building, located in a congested and busy area. As a large crawler crane would have required a road closure, ALE’s Lightweight Service Crane was the only possible solution that avoided disruptions.
All of the Lightweight Service Crane’s components were mobilised with a small truck and onto the roof using the service lift and one staircase.
The crane was configured on the roof in its largest configuration, with a backmast of 7.8m and boom length of 11.2m.
It took just one day for the crane to lift all of the eight BMU components on the roof-top.
