Why 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
Brushes Spares 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

9. 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.

10. Pins and Circlips 2 Circlip Type Headed Pin & circlip Lock Pin type

Only used in 3122 Links
Headed Pin & Collar
Cheaper version of above
And circuit conveyors
FHM
Corrosion resistant properties
Heat treatable stainless steel
Available as an option on 3002,3,4
Circlips are available as Mild Steel (standard) or Cromweld 3Cr12 (Corrosion resistant steel)

11. Manganese & Runners Basic Info - Used with flat bottomed Links
- Used with V bottomed Links
MC Range – Runs On Mild Steel Flat Runners

12. Sprockets and Trailers
Trailing Wheel
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.

13. Why Buy Redler ? Drop forged from alloy steel Precision machined
Case hardened to RC57 min
High tensile strength
Consistent dimensional accuracy
Manufactured to stringent quality procedures ISO 9001:2000
