MUK 402

Our tridem range gives you loading volumes up to 50 m³ with a maximum permitted total weight of 34 tonnes. Alongside the standard parabolic spring suspension, hydraulic and pneumatic suspension systems are available. In the basic version, both front axles are fixed and the third axle is a self-steering axle. From the manufacturer's view, we recommend a forced steering system for the first and the third axles.
