The plant features a 2612V Vari-Vibe high frequency screen. The two-deck, 1.8 x 3.7 m (6 x 12 ft) screen uses a rotary tensioning system that allows for some of quick screen media changes, allowing producers more uptime.

It also has deck-mounted, variable-speed hydraulic vibrators, a hydraulic mechanism for varying operating angles, a fines collecting hopper, top and bottom deck discharge chutes and an aggregate spreader.

The plant includes a large hopper with a capacity of 6.1 cubic metres (8 cu yd) that is equipped with 15.2 cm (6 in) sloped grizzly openings and a remote tipping grid, while the variable-speed, 122 cm (48 in) wide belt feeder features a high-torque hydraulic drive, full length impact bed, rubber lagged head pulley and self-cleaning wing tail pulley.

The screen plant is equipped with four conveyors: a delivery conveyor, two side conveyors and a fines conveyor. All conveyors feature a variable-speed hydraulic drive and easily fold for transport.

The GT2612V is powered by a Caterpillar Tier 4 Final, (101.4 kW (136 hp) engine, while engine-mounted hydraulic pumps operate all plant functions.
