Mid-class production power

HT-450 Power Pack

456 CAT horsepower and 150 GPM of dedicated attachment hydraulics on your existing carrier — matched to mid-size excavators and cutterheads that don't need the full 575-class package.

What it is

Right-sized power, same Powertek build

The HT-450 is the HT-575's mid-class sibling: a self-contained CAT-powered hydraulic unit that mounts on a standard excavator and gives the work tool its own dedicated flow and pressure, independent of the carrier's hydraulics.

It's built in the same Concord shop, on the same 280 drive-pump architecture we've refined across two decades of power-pack manufacturing — and it pairs naturally with the CH-120 and CH-150-280 cutterheads.

Quoted per build — carrier, head, guarding, and options are matched to your application. Call and we'll spec it against the work you actually do.

Running a bigger head, heavier material, or longer production days? The HT-575 delivers 577 HP and 200 GPM on the same concept — and the XPE excavator builds the whole machine around the tool.
