What size excavator or loader do I need for a rotary screening bucket?

Expert Answer

The right machine size depends on three things: operating weight, hydraulic flow and pressure, and the lifting capacity at the working radius. Rotary screening buckets are commonly matched to compact carriers for landscaping and utility work, and to larger excavators or loaders for heavier demolition, quarry, or bulk soil processing. It is not just about machine weight; if hydraulic flow is too low, screen rotation slows, and if lift capacity is marginal, handling wet material becomes inefficient. You also need the correct mount, hose routing, and, on some machines, case drain or drain line confirmation. If you run a Caterpillar, Komatsu, Bobcat, or Kubota carrier, VANROCK can check fitment, though VANROCK is an independent manufacturer and not affiliated with those OEMs. We manufacture and supply rotary screening buckets and can review your machine specs to recommend the correct size and provide a quote.
