The driver's cab on the U 4000 or U 5000 has everything to make everyday tasks as ergonomic and safe as possible for the driver and his team. The interior with noise-insulating trim and luxury seats provides generous stowage areas and headroom, e.g. for when helmets are required in operation. The flat cab floor throughout ensures free entry and exit and the air-conditioning system and the auxiliary heating ensure a pleasant atmosphere in any situation.
