The best-selling boom system with high speeds and smooth operation achieved by using plastic rollers and low-maintenance extension ropes. This system has been exceptionally successful at STEPA both for agricultural and forestry use for over 20 years. The compressive lifting cylinder of STEPA’s load arm means low oil warming at higher working speeds during lifting and lowering of the load arm.

Extremely narrow stables could be equipped with a crane for the first time after STEPA brought the quadruple telescopic crane onto the market in 1997 as the first manufacturer of what was then the Quattro crane. It also became possible to reach distances of up to 15m horizontally and 17m vertically.
