Drive train & power supply

The truck is powered by an electric synchronous motor that drives the first and third axles. The power supply comes from the battery pack or directly from the diesel generator. There is also a hybrid propulsion option, where both energy sources are used. When the truck is braked, the energy released is recovered in the battery. Whether the crane is travelling or in operation, its energy supply can come from three different sources:

Fully electrical (battery)
Hybrid (combination of generator and battery)

3 in 1 Cabin

The SK487-AT3 is the first mobile tower crane to be fitted with a single cabin. The cabin functions as a truck cabin, lift cabin and crane cabin all in one. In crane mode, the cabin can be moved to any desired height, always solidly connected to the crane, so the operator maintains full feeling and control over the crane at all times. The cabin is very spacious, with a large window area to optimise not only visibility and comfort but also safety. The cabin’s internal dimensions are 970 x 1670 x 3130.
