The new generation of the AHK 36e electric trailer crane is a true marvel of efficiency! It’s perfect for anyone who wants to work all day long on battery power without having to recharge. The electric crane is impressively quiet and faster than any other trailer crane before it.
The crane’s extremely low energy consumption, combined with a powerful battery capacity of 12.2 kWh, ensures sustained operation without a power connection. Thanks to a cutting-edge drive system with high efficiency and a completely newly developed electric winch, the AHK 36e not only requires very little energy—it also recovers energy when lowering the load via the cable winch and feeds it back into the battery. The electric winch also enables impressive rope speeds of up to 100 m/min, making the lifting of loads even faster and more efficient. After work or during operation, the unit can be conveniently charged using 230 V from any household outlet. If there is insufficient Protection on site, the charging power can be reduced as needed. If necessary, the boost function also increases the charging speed.
A full workday, independent of power outlets
During the roof renovation of an old farmhouse, the new AHK 36e with an electric winch impressed the team at M. Höfges Roofing in Issum. In no time at all, the electric crane lifted the roof boards and battens into place for the reconstruction of the pitched roof. The three-hour operation was powered entirely by the crane’s battery, including maneuvering, setup, and takedown. At the end of the job, the remaining charge was still at 70%. Despite the frigid temperatures near freezing, the lithium-ion battery technology delivered reliable performance with stable charging and discharging characteristics. In addition to the battery’s impressive range, the roofers particularly praised the new AHK 36e’s pleasantly quiet operation, precise handling, and very fast working speed.
Maneuvering to the setup location in the yard, erecting the crane, leveling the outriggers, and raising the mast required a total of only 8% of the battery charge. The AHK 36e then performs up to 140 routine lifting operations without needing to recharge its battery. With a battery capacity of more than 10 hours under normal use, the electric crane can work flexibly and independently on the construction site all day long.
Powerful Performance in Every Respect
The new electric AHK 36e is not only independent of a power outlet; it also offers all the familiar advantages of Böcker’s most powerful trailer crane. Thanks to its state-of-the-art boom system, it achieves boom lengths of up to 34 m (opt. 36 m) and lifts loads of up to 1,000 kg (opt. 1,500 kg) with a gross vehicle weight of just 3.5 t. Even with a suspended load of up to 1,000 kg, the boom can fully extend. The standard tandem axle on Böcker trailer cranes ensures a smooth ride on the road and safe maneuvering on the construction site. The manoeuvring drive also benefits from the new drive concept, and the crane now maneuvers even more nimbly to its setup position. The familiar swivel drawbar significantly reduces the setup footprint.
Furthermore, the AHK 36 features a large outrigger lift with a ground clearance of up to 50 cm. The flexible outrigger system, with variable positioning of each individual folding and swiveling outrigger, allows for many different setup configurations. This makes setting up the crane next to obstacles and on slopes a breeze. In Issum, the crane was set up in the yard of the house between three trees in a space-saving manner that optimized reach.
Thanks to the AHK 36e’s new drive concept, it’s not just the winch that impresses with its high rope speeds. The crane’s other functions—such as rotating and raising the mast, as well as telescoping—can also be controlled simultaneously at high speeds. The mast’s swivel range is virtually unlimited.
The innovative crane control system, combined with the radio remote control, assists the operator and enables precise and intuitive operation of the trailer crane. Numerous software functions ensure great ease of use and maximum operational safety. Both setup and takedown can be controlled automatically via the radio remote control. For repair and maintenance work, the AHK 36e can also be quickly converted into an aerial work platform with a working height of up to 29 m.
