This payload category has been covered by the classical combination system type STZ-VL or STZ-VH/ET so far. The users, however, required a lighter, more compact and easier to operate vehicle system.
The compact construction, the low deadweight, the high axle load, the extreme extensibility as well as the deep and wide excavator recess in the bogie make the new system attractive.
Great value was put on the use of proven components like pendular axles with an axle compensation of +/-300mm during the development. Bogies, crawler deck and gooseneck are newly conceived and trimmed to the shortest length in order to obtain the largest possible loading surface in the total combination.
The compact gooseneck has a new two-circuit steering system making this vehicle manoeuvrable and offering extra security. The new vehicle type is available in two-axle to eight-axle versions, including one-axle, two-axle or three-axle platform bogies at the front.
The compact two-axle and three-axle rear bogies have a vehicle width of 2.550 or 2.750mm, whereas the four-axle and five-axle bogies measure 2.750, 2.850 or 3.000mm in width.
The compact system is extremely easy to service and to operate. Due to the through excavator recess with a width of up to 950mm, the excavator boom can take a deep position on the vehicle.
Various decks having a payload capacity of over 100t, as well as a newly conceived excavator deck with extreme extension lengths, in conjunction with low dead weights and construction heights are available to provide economical and flexible transportation of a variety of loads.
This extension system enables the carrier to obtain a short combination length while driving empty and an extremely long loading deck if needed.
