Dymax Wood Chip Scoop mounted on a Cat wheel dozer, filled to capacity while dozing a large wood chip pile at a biomass site

Dymax Woodchip Scoop

Heavy-Duty Blade-Bucket for Biomass and Power Plant Applications

Get the biggest yard with a Dymax Woodchip Scoop. It combines the best of a rollout bucket and a dozer blade, so one machine dozes the pile, carries the load, and feeds the hopper.

A mesh screen keeps the chip pile in the operator’s sightline through the whole dump. Integrated tilt and forward tip place the load.

Available for Cat 816-834 wheel dozers.

FAQ

A wood chip scoop is a wheel-dozer attachment that dozes a chip pile like a blade, then lifts and dumps the load into an elevated hopper or chute — the kind that feeds a biomass boiler or power plant.

It’s built on a full floor with a bolt-on cutting edge (similar to a bucket) and carried by an H-frame push group.

One machine handles the whole move from ground pile to hopper feed.

A rollout bucket loads and dumps, but can’t doze the pile.

A wood chip blade dozes, but can’t lift and dump.

The wood chip scoop does all three — push, lift, and dump — so one wheel dozer covers a job that would otherwise require two machines.

It’s built for Cat wheel dozers, including the 816, 824, and 834. Each scoop is matched to the machine’s size and breakout force.

Hopper height, chute position, and chip type differ at every plant, so every wood chip scoop is made to order.

Capacities run up to 39.5 yd³ lift-and-carry and up to 65 yd³ doze. Widths up to 190 inches. All sized to the machine.

The bigger the class, the more pile you turn and the faster you feed the hopper.

The cutting edges are replaceable Cat-pattern bolt-on edges.

Only a handful of companies in the world build a wood chip scoop like this, and Dymax is one of them.

The design traces back to the Balderson family, who pioneered oversized dozer blades — the same family that builds Dymax attachments today.
