Duxson

Duxson equipment is manufactured in New Zealand and represented in Australia through Randalls, covering forestry grapples and felling heads for felling, bunching, log loading, woodlot thinning, sorting and stacking.

New Zealand manufacture is commercially relevant to Australian buyers for a practical reason: the terrain, species and contracting structures across the Tasman are closer to Australian conditions than most northern-hemisphere design assumptions, and freight and lead times are shorter than from Europe or North America.

In the grapple and felling head category the deciding factor is rarely headline capacity. It is geometry — closing profile, tip shape and jaw count — matched to how your material actually moves.

Felling heads and forestry grapples are frequently sold on capacity figures that tell a buyer very little. What decides productivity is how well the geometry suits the stems and bunches you actually handle, and how quickly the assembly cycles.

For felling and bunching, the number that matters most is accumulation — how many stems the head holds before placing. In small-stem work, a head that accumulates several stems per cycle transforms the economics against one that places each stem individually, regardless of their respective maximum cut ratings.

For loading, sorting and stacking, closing geometry and rotation control govern. A grapple that needs a second grip to secure a log has lost a share of every cycle, and across a shift that compounds into real lost tonnage.

Whatever the application, check the lift chart with the full assembly fitted — head or grapple, plus rotator, plus coupler — at the radius you genuinely work at. That remaining capacity, not the attachment rating, is what determines what the machine can safely handle.
