Marathon Vibratory Conveyors with Monobeam Construction

Marathon vibratory conveyors with monobeam construction feature a narrow frame that’s less than half the surface area of traditional Marathon frames. Monobeam shakers offer better access to the conveyor bed and fewer parts to clean. Available in lengths from 9 to 15 m, this is Key’s longest monobeam conveyor.

Ideal for processors that need a high degree of equipment hygiene and/or a small footprint, Marathon with monobeam is suitable for a wide range of bulk food applications, from raw receiving to packaging, including product collection, transfer, and distribution. Unlike a traditional shaker, which has a frame and spring arms on both sides of the conveyor bed, monobeam conveyors position the frame and spring arms underneath the bed to maximize sanitation while improving operator access and safety.

All Marathon conveyors use natural-frequency vibratory motion to distribute bulk foods long distances on a single unit. Marathon can replace several shakers in a row, relying on only two independent, frame-mounted drives to improve efficiency and reliability. Two foot-mount, self-synchronizing motors transfer the force of the frame to the bed without mechanical joints to further improve efficiency, reduce maintenance and minimize downtime.

Key tailors each Marathon using predictive modeling and Finite Element Analysis to define the product characteristics and deliver superior performance. Available in lengths from 9 to 15 m (30 to 50 ft) and widths from 50 to 100 cm (20 to 40 in.), Marathon with monobeam can achieve conveying speeds greater than 15 m (50 ft) a minute, depending on the application. The conveyor bed can be tilted to draw product to one side, and flow direction can be controlled with optional side outlet diverters. Marathon with monobeam can be built with end-mounted drop-out gates, diverters, end-mounted screens, and covers when needed.

Its stainless-steel conveyor bed features a standard rotary polish within the product contact zone, which resists bacterial attachment and biofilm formation. Oil-free drives, elastomeric isolators, scalloped flat bars, internal ground arms, and minimal laminations maximize equipment hygiene and help meet rising sanitary standards and regulatory requirements. The frame is sloped to prevent product and moisture build-up that can harbor bacteria.

Marathon with monobeam is suitable for fruits, vegetables, potato strips, potato chips, nuts, meat, poultry, seafood, dairy products, confections, snacks, cereals, grains, seeds, and more.
