SERVES YOU WHEREVER YOU SERVE

Configurations for all types of missions
The HD9 rigid version is the ideal vehicle for transporting materials, goods and people in off-road conditions, on arduous and rough terrain. Available in 2, 3 and 4-axle versions, it has a GVW up to 65 tons depending on the configuration. The HD9 rigid version is designed to be easily set up in numerous different configurations, thanks a simple and reliable mechanical-electronic structure. The HD9 rigid version suits any type of equipment: from a tipping body for transporting aggregates from quarries or mines, to construction machines such as concrete mixers, concrete pumps or mixer pumps, platforms and cranes to special configurations like workshop or firefighting vehicles .
