Our shaker motor can rotate clockwise to screen maximum material during normal padding operations and counter-clockwise for downhill padding to clear material off of the shaker screen efficiently. Hydraulic cylinders in the rear of the shaker system allow height and angle control of the shaker, independent from the conveyor. The operator can freely adjust the height of the shaker when padding on an incline to facilitate material production.

A vibrator located below the spill pan can be turned on to loosen debris when operating in wet or heavy material conditions.

OPP-300 Shaker


It is powered by a 6 cylinder Liebherr D936 LA6 engine built to withstand extreme temperatures and altitudes.

The D936 engine boasts high power density, long service life, optimum efficiency, low vibration levels, and high torque.

Screen Size

The OPP-200 series uses screen sizes ranging from 1/4" to 4". The screen size can be increased in 1/4" increments. 

All screens have been tested for accuracy to ensure only the correct size of material gets through every time.

Video Monitoring System

Four high-resolution, color, anti-glare cameras deliver crisp images in direct sunlight. Nitrogen-sted camera housings keep dust out, while the enclosure keeps the camera free of condensation, frost, and moisture-proof. Installed shock absorbers remove the effect of impacts and vibrations, while protective casings prevent damage from falling rocks.

There are three monitors inside the cab, which display three views; down the elevator, conveyor output, and the left side of the machine. A rear-view camera automatically engages six cameras when in reverse.
