For ease of handling conveyor chains, they are divided into lengths of approximately 3m long, so they must be joined on site to make the required length. They must also be cut and spliced when replaced. The method is described below

Caution
  • Use jigs (stands, press plates) for cutting and joining work.

How to Cut a Conveyor Chain

Conveyor chains are delivered in approximately the form below. Follow the methods below to disassemble the chain at a joint end (position A), or at the middle (position B).

How to Cut at a Joint End

To cut the joint end, use a stand as shown in the diagram below, place press plates 1 and 2 over the pins, then hit (a) and (b) alternately with a hammer, to remove the pins.

Central Disassembly

(1) Extract the T Pins (Split Pins)

Remove the two split pins at the break point. Use a spanner or pliers to straighten bent T pins or split pins for extraction.

Caution
  • Do not reuse straightened T pins or split pins.

(2) Extract the Pins

To break a chain in the center, use the stand as shown below, place press plates against the pins, and then hit (a) and (b) alternately with a hammer, to remove the pins.

Caution
  • You must place press plates over the pins before hitting them with a hammer.
  • The pins are hardened by heat treatment, so they could break if struck directly, possibly causing injury.

How to Join Conveyor Chains

(1) Chain Joining (Push Fitting Outer Plates)

To join the chains, use press plates (jigs), as shown in the diagram below, to strike alternately around the holes at (a) and (b), pushing the plate into place.

(2) T Pin (Split Pin) Bending

After pressing the outer plate into place, insert the T pins (split pins) and bend them securely.

Caution
  • Use a spanner or pliers to bend the T pins (split pins). Avoid hitting them with a hammer.
  • Bend T pins through 30º and split pins through 60º, as standard.
