AHK 36e: Trailer crane with 230 V loading technology takes over material transportation

With the Böcker AHK 36e trailer crane, the free choice of location on the construction site is guaranteed. Thanks to the electric drive and battery, the crane can be set up anywhere, operated autonomously and charged via the 230 V technology at any normal household socket during operation. During a test application for a roofing company, the AHK 36e demonstrated both its performance in battery operation and an immense reach for re-roofing the rear side of a single-family house. First, the AHK 36e drove to the optimal installation site in the house driveway via manoeuvring drive. Independent of an external power supply, the lithium-ion battery provided the energy for maneuvering and the crane setup. Afterwards, the old concrete roof tiles were teared down, which the crane removed from a distance of 23 m over the ridge and into the container. During each lifting operation, the tipper basket was filled with around 250 kg of old material. Due to the electric operation via the 8 kW electric motor, the removal works in the middle of the residential area were quiet and at the same time very efficient. Within two hours, the roof was ready for re-roofing. In the next step, the AHK 36e lifted soft wood fiber insulation boards for above-rafter insulation over the building. Here, too, the trailer crane showed its long reach and moved a load of 250 kg on the pallet fork to the laying site.
