Stertil-Koni has introduced five new air-over-hydraulic jacks designed for heavy-duty applications such as trucking, transit, agriculture and construction.
Chrome-plated lifting rams promise extended service life, while the jacks also include hydraulic protection against overloading.
Controls at the end of the handles require constant pressure while operating the jacks, in the name of safety. And there are standard two- and four-inch height extensions.
The single-stage Model S25-1 offers a capacity of 55,000 lb., while the Model SK25-1H for high-clearance applications has the same capacity. The two-stage SK25-2 is for buses and trucks, and features a 55,000-lb. capacity, while the four-stage SK40-4 four-stage jack for ultra-low transit vehicles offers a maximum capacity of up to 88,000 lb. Rounding out the lineup is the three-stage Model SK50-4, supporting low-clearance vehicles, with a capacity of up to 110,000-lb.
