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

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

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.
