Cleats/Flight Bars: Height 50-300 mm, Thickness 3-12 mm

Component Specifications

Definition

Cleats or flight bars are structural attachments mounted perpendicularly to conveyor belts or chains in elevator conveyors. These components form discrete pockets or compartments that contain and elevate bulk materials (such as grains, powders, pellets, or aggregates) along vertical or steeply inclined paths. They prevent material rollback, ensure consistent discharge, and maintain separation between different material batches during transport.

Working Principle

Cleats/flight bars operate by creating physical barriers on a moving conveyor surface. As the conveyor belt or chain moves upward, these barriers trap material against the belt, forming sealed pockets. The material is carried vertically until it reaches the discharge point, where centrifugal force, gravity, or scrapers empty the pockets. The spacing, height, and shape of cleats determine capacity, material retention, and discharge efficiency.

Materials

Typically made from abrasion-resistant steel (AR400/AR500), stainless steel (304/316), UHMW polyethylene, or engineered plastics like nylon or polyurethane. Material selection depends on application: food-grade stainless steel for sanitary environments, UHMW for low friction and corrosion resistance, or hardened steel for heavy abrasive materials.

Frequently Asked Questions

What is the difference between cleats and flight bars?

Cleats are typically shorter, more numerous attachments for fine materials, while flight bars are larger, more robust structures for heavy or coarse materials. Both serve the same function of creating material pockets.

How do I select the right cleat material?

Consider material abrasiveness, corrosion potential, sanitation requirements, and operating temperature. Use stainless steel for food processing, UHMW for chemical resistance, and hardened steel for mining applications.

What maintenance is required for cleats/flight bars?

Regular inspection for wear, cracks, or loose fasteners; cleaning to prevent material buildup; and timely replacement when wear exceeds 20% of original thickness to prevent conveyor damage.
