Truck Crane AK 37 / AK 37e

The Böcker truck crane AK 37 sets new standards among aluminium-steel hybrid truck cranes up to 7.49 t gross vehicle weight. Having a maximum payload of three tons as well as extensions lengths up to 37 m this crane is perfectly suitable even for challenging tasks during the daily work on a construction site. No matter if heavy pallets with bituminous felt or even grit containers have to be lifted, there are numerous fields of application thanks to the solid design of this crane.

Due to outstanding lateral working ranges the truck crane AK 37 easily lifts loads even to the rear side of the roof. The sophisticated PLC Control ensures that even enormous loads can be transported exactly and safely to the respective place of destination. Each of the four telescopic outriggers can be controlled separately so that the crane can be ideally adapted to the situation on-site. Hereby, the PLC control continuously monitors the position of each single outrigger and shares automatically the maximum working range subject to the present charge. As a result the Böcker truck crane AK 37 provides maximum safety as well as an ideal utilization of the maximum working range even under extremely challenging circumstances. The new radio control with full colour display and optional camera technology also ensures an easy and safe use of all crane functions.

Sustainable drive technology

The AK 37 is optionally available as a 230 V crane with additional electric motor and battery or as a 400 Vhybrid crane. Especially in densely populated areas, the low-emission and low-noise operation offers great advantages. With an output of 13 kW, the 400 V drive is as powerful as usual. Thanks to the adjustable fuse protection, the crane utilises the maximum available current at the construction site at any moment.

As the first mobile crane on the market, the AK 37e can be equipped with a 230 V electric motor that charges at any classic household socket thanks to battery technology. The AK 37e works electrically almost everywhere - a decisive advantage especially for refurbishment and repair jobs in residential areas. At the same time, the readily available connection to a normal power socket enables permanent electrical use on any building for the first time. The modern lithium-ion battery charges directly during crane use so quickly that the battery level remains constant during everyday operation and all crane functions can be seamlessly continued. The powerful battery capacity also allows the crane to operate autonomously for a long time, even without an external power supply and without switching on the PTO power take-off.

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.

Optionally, the hybrid truck crane can also be operated at any time via the truck engine's auxiliary drive. Here, state-of-the-art engine technology with exhaust gas cleaning and AdBlue injection is used. In addition, all Böcker cranes exclusively use durable, biodegradable hydraulic oil of the lowest water hazard class.
