Trailer Crane AHK 36 / AHK 36e

The AHK 36 is the most powerful trailer crane of its class. Thanks to its' sophisticated boom this crane reliably reaches heights up to 36 m and lifts loads up to 2,400 kg. The ultra-modern Böcker mast technology is the foundation for this outstanding performance data. This Böcker technology combines proven aluminium components and a new high-strength steel which is lightweight and strong at the same time. Therefore, the AHK 36 clearly outperforms all other comparable cranes.

The version of the AHK 36 equipped with a petrol engine will work even quieter in future, with improved insulation reducing noise emissions by seven decibels compared to the predecessor model. The AHK 36 is mounted on a tandem chassis ensuring a safe driving behaviour and an optimal distribution of floor load. Another important innovation is the Fall Protection Mode. In this new operating mode, the trailer crane can now be used to protect people from falling when working at height, e.g. during repairs on the roof. A safety device is suspended from the load hook of the crane, which connects the person to the crane via a wire rope within a certain radius of action.

Beside its strong performance, the AHK 36 clearly stands out by its tremendous versatility. The Multiflex outriggers can be set up in 256 different positions using auto-levelling and therefore assuring maximum utilization of the available space on site. The foldable swivelling outriggers ensure an optimal positioning of the machine in the direction of the load. Furthermore, they can easily be swivelled around any barriers. At the same time, it is possible to balance out height differences up to 50 cm without the need of an additional sub-structure. No other support system in the field of trailer cranes provides comparable opportunities.

The new Multiflex outriggers are combined with the Böcker EHSC control. This high-performance control in 32 bit technology enables an exact processing of any control command. Being equipped with the latest CAN-bus technology as well as two independent safety controls, the AHK 36 provides maximum safety. This concept is certified by the German technical inspection authority DEKRA.

Sustainable drive technology

The AHK 36 is optionally available fully electric with an electric motor instead of the classic petrol or diesel engine and with 230 V charging technology. Particularly in densely populated areas, the low-emission and quiet operation provides excellent advantages.

Where 400 V high-voltage current was required in the past, the AHK 36e will be the first trailer crane on the market to be charged at any conventional 230 V household socket in the future - in an innovative parallel operation directly during the crane operation. Independently of any external power supply, the crane moves to the optimum installation site by means of its manoeuvring drive and the set-up is as well effected powered by the battery. The power consumption of the AHK 36e is optimized to a degree to require significantly less energy than comparable cranes with combustion engines. The high battery capacity permits more than three hours of operation or eight standard working cycles without an external power supply. In stand-by mode, the battery can be charged from 20 % to 80 % in less than one hour. 

In order to minimise the energy intake, a sustainable a sustainable stop-and-go-automatic device limits the energy consumption of the trailer 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. In addition, all Böcker cranes use exclusively biodegradable, long-life hydraulic oil of the lowest water pollution class.
