AHK 36e – First battery-operated trailer crane with 230 V charging technology

Free choice of location guaranteed: In addition to an environmentally friendly and independent operation thanks to its electric drive with energy storage, the 230 V charging technology permits setting up and operating the AHK 36e anywhere.

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.

Thanks to modern lithium-ion battery technology, the AHK 36e can operate permanently in plug-in mode without any loss of capacity. In stand-by mode, the battery can be charged from 20 % to 80 % in less than one hour. During operation, the crane is charged parallelly at a high speed guaranteeing a constant battery charge level with all crane functions continuing smoothly. To minimize energy consumption, a sustainable stop-and-go automatic system limits power consumption and activates the electric motor only when necessary. The low power draw maintains the battery charge level and extends the operation time without an external power supply.

In addition to making load lifting operations more sustainable, the new AHK 36e offers all established advantages of the class leader among trailer cranes. With an 8 kW electric motor, it lifts up to 2,400 kg with low emissions and low noise, and reaches extension lengths of up to 36 m with a GVW of only 3.5 t. It is equipped with foldable swivelling outriggers, auto levelling, rotation and erection angle limitation of the mast package, and go-home function. The Easy-Lock system allows converting the new battery-operated trailer crane into a work platform in no time at all. The crane can as well be used for fall protection in the personal security mode.

 

Detailed presentation of novelties

Böcker is going to organize the first presentation of the AHK 36e and an overview of the entire range of the Böcker height access technology at the 360° Height Days on April 1 and 2 at the company headquarters in Werne. The new trailer crane will also be on display at Vertikal Days in May, the DACH+HOLZ International in July, and bauma in October.

 

Without external power supply, the strong battery capacity lasts for three hours of use or eight everyday work cycles.

The trailer crane charges at any classic household socket with 230 volts.

The level indicator provides information about the charge status of the battery at any time.

The AHK 36e is the first battery-powered trailer crane that can operate permanently in 230 V socket operation.
