ALLGUARD™

THE ALLGUARD ADVANTAGE
Ramsey's ALLGUARD conveyor chain is designed to extend chain life and improve product handling, especially in applications where conveyors run in contact with lateral guides or transfer plates. Using highly wear resistant links that cover and protect the sides of the chain, ALLGUARD runs in direct contact with lateral guides, immune to the pin head wear that can destroy typical chains.

Allguard protection can be added to Ultralife or Ramsey Standard Chains. Allguard I has guard protection on one side of the chain; Allguard II has guard protection on both sides of the chain. Contact Ramsey for more information.

HOW IT WORKS
Typical chains contain pins that extend from the sides of the chain (Figure 2). The ends of these pins, which are headed or riveted to hold the chain together, are vulnerable to wear and chipping when they contact lateral guides or transfer plates. In time, the wear may be severe enough to cause chain failure. Operators may try to prevent this problem by creating a gap between the chain and transfer plate. In some instances, this gap can interfere with the smooth transfer of items across the chain. ALLGUARD chain eliminates these typical chain problems.

As shown in Figure 1 and 1A, special ALLGUARD side links act like a coat of armor, completely covering and protecting the ends of pins. This allows the chain to be operated in direct contact with lateral guides or transfer plates, eliminating gaps that can prevent smooth product transfer (Figure 3).

ALLGUARD side links are case hardened for maximum wear resistance and
extended service life (surface hardness of Rockwell 60C or higher). Other products
use softer stamped side links or even powdered metal links. No other chain offers
the wear protection of ALLGUARD (Figure 4).
