Mercedes-Benz SK-II 2644 from 1994 - 1998

The model
The model is a conversion from a kit of a 2-axle tractor unit to a 6x6 tipper with a large number of individual components. The model has a 3-speed gearbox with an attached distributor gearbox so that the power can be transferred to the front axle or switched off. As the original driver's cab comes from long-distance transport, it is shortened by 30 mm to make a true-to-original driver's cab for construction site vehicles in local transport.
