Truck Crane AK 42/4000

The power package on a 16 t or 18 t truck

The truck crane 42/4000 combines maximum ranges and payloads up to 4,000 kg on a compact ruck of 16 or 18 tonnes. With a winch of 2 tonnes, the AK 42/4000 is able to lift up heavy loads. However, the strengths of the crane are its ranges. Even under a load of 1,000 kg, the crane reaches a range of 22 meters. Therefore, the AK 42/4000 is good for the ambitious roofer, carpenter or solar and metal installation builders. Being a versatile machine, the crane can surely be converted to a lifting platform within a short time.  

Thanks to the stable mast package made of aluminium, a precise settling of the load is guaranteed all the time. Like all the other models the crane retracts or telescopes quickly and safe even under load. By the design-related incredibly low swivel radius, working is easily possible in streets even with running traffic.

Sustainable drive technology

The AK 42/4000 is optionally available as a hybrid crane with an additional electric motor. Particularly in densely populated areas, the low-emission and quiet operation provides excellent advantages. The 400 V drive works as powerfully as usual with an output of 30 kW. Thanks to the adjustable fuse protection, the crane utilises the maximum available current at the construction site at any moment. In order to minimise the energy intake, a sustainable stop-and-go-automatic device limits the energy consumption of the hybrid crane. The control system registers movement requirements activating the electric motor only when required. During idle times and waiting times, the automatic system saves valuable resources. With the eReady kit, the truck crane can be prepared for a subsequent retrofit of the eDrive.

If there is no power supply on-site, the hybrid truck crane can optionally be operated via the power-take-off of the truck engine. This is where the latest engine technology with exhaust gas cleaning and AdBlue injection is used. In addition, all Böcker cranes use exclusively biodegradable, long-life hydraulic oil of the lowest water pollution class.
