The Böcker truck crane AK 37/4000 PLC sets new standards among aluminium-steel hybrid truck cranes up to 7.49 t gross vehicle weight. Having a maximum payload of four 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. Due to outstanding lateral working ranges the truck crane AK 37/4000 PLC 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 37/4000 PLC provides maximum safety as well as an ideal utilization of the maximum working range even under extremely challenging circumstances.
