Variations to Links
• Through hardening – Maximum Tensile Strength
• Anti wear bushes – Split Type – Anti Wear Solid Stainless – Anti Corrosion (Used in conjunction with FHM Pins)
• Keyways Link Keywayed in Male end to force articulation in bushed female end.
Significant cost implications are involvedwith bushed links
Link with keyway
Pin with locking pin
Hardened Bush

Flight VariationsWhy used How Common Application
Scavengers To remove material from inside of conveyor
Hard welded edges and ground to cutting edge
Anywhere where build up is likely
Diggers To stop chain rise on larger particles
Angled and chamfered flight
Cement Clinker
Pads To clean material from Elevator
Nylon or Neoprene pads To maximise clearout on Elevators
BrushesSpares only
To brush material from bottom of conveyor
Bolted on nylon brushes Grain Conveyors
Blanking Plates
To assist En-Masse Elevating
Welded steel plates For elevators where material will flow back
UHMW Sleeve
Used on MC Range for silent running
Plastic sleeves over steel flights
MC Range
Scoops To return over-carry of material in D/E
Steel or Plastic Grain machines
Flight Configurations
Chain Configuration
• Links are assembled in a configuration to match individual applications.
• This configuration can include scavenger, cleaning or pad flights as required.
• Within a complete chain, flighted links are usually supplied at every single, second or third pitch. See sketch showing typical arrangement of a ‘T’ type chain. Alternative configurations available.
• Chain is usually supplied pre-assembled into 3-metre lengths complete with connecting pins.
• All assembled chains supplied with appropriate protective coating.

Basic Info
MC Range – Runs On Mild Steel Flat Runners
Sprockets and Trailers
• REDLER LTD manufacture a range of quality sprockets and trailers to match the drop forged chain.
• Sprockets with or without detachable flange segments.
• All wearing surfaces hardened for improved life.
• All items designed with full boss that includes a keyway and grub screw for secure shaft mounting.
• All items can be supplied with high strength shafts.
Sprockets Trailing Wheel
Why Buy Redler ?• Drop forged from alloy steel
• Precision machined
• Case hardened to RC57 min
