This just-released radial stacking roller bed conveyor can be adjusted to up to 11 feet high so material can be fed directly into a loading vehicle or larger stockpiles can be created.

Lake Erie Portable Screeners has added three roller bed conveyors to its line of screening equipment. The company designed the new ground, stacking and radial stacking conveyors to withstand the demands of processing materials in industries including landscaping. They can be used with the company's Pitbull• 2300 screening plant to produce three grades of material at once.

According to the manufacturer, roller bed conveyors move heavier loads faster and with less power than slider bed conveyors, which typically have smaller drive pulleys that require more torque to operate. And because the belts move across rollers instead of the entire surface of a slider bed, they operate with less friction, which translates to longer belt life.

Stuart Foradora, factory representative, said overall the conveyors are uncomplicated, easy to service and very portable. They also provide easy belt tracking.

The ground conveyor is mounted on a steel frame that rests directly on the ground, and its large footprint is designed to provide exceptional stability.

Users can adjust the stacking and radial stacking models from five to 11 feet high and feed material directly into a loading vehicle. The adjustability also allows users to create larger stockpiles, which increases efficiency by reducing the number of times equipment needs to be moved. These attributes and others reduce cycle times and haulage costs associated with loading and unloading material when using stationary plants.

The radial and radial stacking conveyors are equipped with wheels and a tow ring or clevis pin plate hitch receiver for easy maneuverability on the jobsite. They also feature 15-inch steel wheels with eight-ply radial tires for smooth maneuvering.

The radial stacking conveyor comes with tire and wheel assemblies that can be positioned to allow the stacker to move on a radius instead of being limited to a fixed point. This allows users to pivot the conveyor left or right in a radial arch.

The standard size of the three conveyors is 30 inches wide by 20 feet long. The manufacturer will also customize designs to provide alternate sizes based on customer needs and applications. In addition to working well with the Pitbull 2300 screening plant, they can be paired with other machines for applications that require independent, heavy-duty conveyors.

These conveyors feature rigid C-channel frames, anti-torque cross members through the length of the main frame, and welded construction.

Heavy-duty pillow block bearings support the pulley shafts and can be greased for smooth performance and longer service life. The ball bearings in the bed rollers are permanently lubricated and sealed to increase wear life and reduce maintenance.

Customers have the option of gasoline engines that deliver up to 18 horsepower or compact diesel engines with as much as 25 horsepower.

The company also offers 220- and 440-volt AC electrical packages for applications in confined or enclosed spaces. These packages offer up to eight horsepower and feature a head pulley motor that's located within the body of the pulley. This protects the motor and minimizes the risk of damage that could occur from other equipment or debris.

The conveyors also can be operated alone with power from frame-mounted independent hydraulic and engine systems.
