Functional and powerful – the new Superlift design
Demag is using its new engineering design for the Sideways Superlift system for the first time ever on the AC 450‑7. This new design is a decisive enhancement to the well-known Demag SSL solution. The Superlift arms are now mounted all the way in the front, on the head of the base section, meaning that they are ultimately longer and accordingly well-suited to larger lifting capacities. And while on the subject of lifting capacities, this means that the AC 450‑7 is considerably superior to other seven-axle cranes – in fact, it even leaves some eight-axle units behind in a number of boom positions.
The functionality and handling have been improved as well. In fact, the new design only requires one single wire rope line for the connection between the main boom head and the SSL arm. In addition, the SSL arms are pinned hydraulically on the main boom, which reduces manual work for securing the arms and the associated work at height.
