2. Small Pitch Conveyor Chains
2.3.5 D Attachment (Extended Pin) In this form, the one end of the pin is extended. The attachment interval can vary the same as the A attachment (Figure 2.26). As shown in Figure 2.27, two sets of D attachment chains can be connected to crossrods, or jigs (such as blocks) may be installed. The extended pins are subjected to bending and shearing forces. The allow- able load of D attachment that is shown in a manufacturer’s catalog is based on a bending force concentrated at the center of the extended pin. The return side of the D attachment chain can be supported by guide rails on the rollers.
