Trailer crane AHK 36 supports restoration of lighthouse

Off the coast of Norwalk in Connecticut, USA, the Böcker trailer crane AHK 36 is used for a repair and restoration project at Peck Ledge Lighthouse.

At this unusual location in the Northwest Atlantic Ocean, the crane assists in the assembly of steel frames, the delivery of material and the removal of old material. Thanks to its lifting bolts on the chassis, the AHK 36 can be easily loaded onto a barge and taken to the lighthouse.

During the six hours on site, the US crane dealer Innovativ Hoisting installs almost 30 prefabricated steel assemblies and removes 3,000 lbs/1,360 kg of old debris. The AHK 36’s long reach and hoisting capacity makes the maintenance work on the lighthouse extremely safe and efficient. The compact footprint of the trailer crane thanks to its adjustable outriggers offersa lot of space on the barge. In addition, a boom lift platform can be positioned on the barge for the installation of selected pieces needing exterior access.


Outstandig reach and small footprint

Thetrailer crane AHK 36 is the class leader among trailer cranes and easily achieves extension lengths of up to 118 ft/36 m and lifts loads up to 5,290 lbs/2,400 kg. The basis for these outstanding performance data is the state-of-the-art Böcker mast and telescope system. Due to the optimum combination of highly tensile steel and aluminium alloys, the AHK 36 clearly outperforms all comparable cranes.

The support technology of the trailer crane guarantees optimal erection geometry, especially in locations where space is limited, such as on a barge in the Atlantic Ocean. Each individual crane outrigger can be extended as far as required and thus every available cm of space can be use. This fully variable extension of the outriggers with up to 256 different outrigger positions enables an extremely flexible erection of the crane, which in turn has a positive effect on the outreach. The foldable swivelling outriggers can not only be optimally positioned in relation to the load. They can also be easily swivelled past or over obstacles. At the same time, floor unevenness of up to 50 cm can be levelled out without an additional sub-structure.

Furthermore, the trailer crane is equipped with a state-of-the-art BICS (Böcker Intelligent Computer Based Safety) control system which, in combination with the radio remote control with full-colour graphic display, enables easy operation and guarantees highest safety during all work processes. Already during erection, constantly updating reach dials make it possible to position the crane optimally for the target area. The Böcker BICS control system includes among others an automatic erection control with auto-levelling function of the outriggers and ensures a sensitive, precise and low-vibration operation. Maximum work range and maximum reach are automatically verified depending on the outrigger position and the attached load. This automatically guarantees safe work at all times. The selectable turn and lift angle restriction also helps you to remain within the available work space. Several software features create operating comfort both in the fore- and background, which is in a class of its own. For instance, the BICS control prevents the load from becoming stuck in any position and also ensures extremely smooth start and precise control of all the crane functions regardless of the operating conditions. The "go-home" function guarantees simple and fast dismantling of the crane after use.


Smart crane technology

As an option the trailer crane AHK 36 can be equipped with the smart customer platform BöckerConnect. It provides crane owners with online and real time information on their vehicle fleet presenting all relevant data of the networked cranes at a glance. After the personal log-in the user obtains an overview of the current status and the location of his cranes. Moreover, the new online platform enables the user to view the current position of his cranes at any time. As soon as the cranes leave a previously defined activity range, he receives a configurable theft report via e-mail. Also the AKH 36 is available with a powerful, low-noise and low-emission 400 V/ 13 kW e-drive.
