Pitbull screening plant is compact and portable

The rugged Pitbull 2300 screening plant manufactured by Lake Erie Portable Screeners gives landscapers, contractors and municipalities a compact and portable machine that delivers maximum efficiency and high outputs with a wide range of materials such as topsoil, mulch, gravel and asphalt.

Lake Erie Portable Screeners developed the Pitbull 2300 with simple operation, maintenance and transport in mind. The machine incorporates several unique features, such as full hydraulic operation, tubular frame construction, a Torflex axle and a reversible shaker, that set it apart for mid-size screening projects. It is available in both diesel and electric-powered models.

The company manufactures Pitbull 2300 frames with high-quality, structural tube steel. The tubular construction reduces noise and vibration, which minimizes the risk of cracks and structural failures that are common in machines with C-channel construction. The screening plant incorporates heavy-duty materials throughout. All the stress points are fully gusseted, and both attachment points and stress points are 100 percent welded with high-strength steel. The result is a machine with a curb weight of 13,440 pounds.

The Pitbull 2300’s 20-foot-long stacking conveyor adjusts hydraulically from heights of 6 feet, 8 inches up to 13 feet to feed material directly into a tri-axle or dump truck. This allows users to create larger stockpiles, which increases efficiency by reducing the number of times equipment needs to be moved. These attributes, combined with the ability to place the machine at the point of excavation, minimize spillage and dramatically reduce cycle times and haulage costs typically associated with loading and unloading material when using stationary plants.

With the machine’s legal width of 8 feet, 4½ inches and either a standard pintle hitch or optional gooseneck towing package, the Pitbull 2300 is easy to move from site to site, as well. A 10K Torflex axle with oil bath hubs provides a cushioning effect so the unit tows smoothly and stress to the tow vehicle is reduced. Upon arrival, users can quickly and easily lower the unit to operating position with the hydraulic system, which eliminates pressure on the axle, tires or wheels during screening. The hydraulic system raises the machine back to towing position with the flip of a lever. The machine also features heavy-duty suspension, electric breaks and trailer lights for safe and legal travel.

The screening plant is equipped with a loading apron that accepts up to three yards of material at a time and up to five yards at a time with a slower dump speed. With its low dump height of 8 feet, 4½ inches, users do not need loading ramps; they can fill the hopper using typical construction equipment like skid steers, backhoes, loaders or excavators.

The portable screening plant also includes an upper and lower screening deck, each with more than 41 square feet of screening area. The upper and lower decks are equipped with two sections of screening media on each deck. The company offers optional punch plate or finger decks for the top deck in addition to a wide range of screen sizes for processing all types of materials. Operators can quickly and easily change screens by loosening tension bolts that hold each one in place. The screeners also can be equipped with optional upper and lower discharge chutes to allow for up to three different sizes of screened materials.

In addition to the adjustable stacking conveyor, the Pitbull 2300 features a hydraulically driven transfer conveyor that moves screened material from the hopper to the stacking conveyor. Hydraulic motors on the conveyors provide a continuous flow of power to achieve production rates up to 100 yards per hour of clean, saleable material. Because the conveyors are hydraulic rather than chain- or belt-driven like many competing models, the Pitbull 2300 eliminates the risk of power loss and downtime due to broken chains or belts.

The unit’s power plant is equipped with a reliable 47-horsepower Yanmar diesel engine that complies with 2008 EPA Tier 4 and EU Stage IIIA emissions standards. The engine compartment features large doors at the top and bottom that open wide for easy maintenance and repair access. The company also offers a 60 horsepower, 480-volt AC electrical package for applications in confined or enclosed spaces like tunnels, mines and indoor projects.
