Keestrack is celebrating an important milestone in its history at CONEXPO-CON/AGG 2026 in Las Vegas this week, marking 30 years since founder Kees Hoogendoorn built the world’s first scalper in 1996.
Now called the K6, the scalper screen has been continuously improved in the decades since, evolving into the most mature and productive scalper on the market. It comes with a heavy-duty plate apron feeder, hydraulically folding hopper walls and a long, wide screening deck – making it suited for applications ranging from coarse scalping to fine screening.
Almost 30 years since the first unit came off the assembly line, the K6 is available as a full hybrid diesel-electric, plug in, or zero drive with no combustion engine onboard.
