Proline Big Banker — Commercial Grade Highbanking for Serious Production
When you need to move serious volume from a bank or gravel bar operation, the Big Banker is the machine for the job. Designed for commercial-grade production, this highbanker combo handles the kind of material throughput that smaller units simply can't sustain. If you're working a rich bench deposit, a high-volume gravel bar, or running a full-day production operation, this is your machine.
The Big Banker features a large blue polyethylene hopper with white PVC standpipe and spray bar — feed material in, water does the work. The Honda GX270 engine powers a high-volume pump that delivers consistent water pressure through two grey layflat supply hoses. The long aluminum sluice box runs a full-length expanded metal grizzly classifier up top to screen out oversize material, with Hungarian riffles and Nomad matting below for maximum fine gold retention.
The power unit sits on its own wheeled frame for easy positioning on the bank. The entire system breaks down for transport and sets up fast at the site. Built to Proline's commercial standard — the same design philosophy that goes into every machine they make: heavy-duty, field-proven, and built to run all day.
