142 -Series - CDM Systems Chains

Sprocket Centres:
Subtract J from the overall chain width
Flight Length:
Subtract K from the overall chain width
Hole Centres:
Subtract L from the overall chain length


To provide the proper chain strength for your application, the data below illustrates the ultimate strength of the chain along with its recommended nominal working load. CDM systems use a 5,5/1 safety ratio for proper application.

Typical applications for the triple TPL series chains include single-strand flight widths up to 30 inches and when used in tandem with DBL series chains(for triple strand widths), flight widths reaching up to 12’-0”(3,7 m.). The etaining mechanisms used to fasten flights onto the TPL link are standard 142 series U-pins or optional 5/16” grade 8 bolts, identical to those used with the DBL-series. Also available for the TPL link are single-slotted flights that can be made in variety of materials, shapes and sizes. These can easily be slipped into the groove of the chain link and fastened with a set of U-pins.

The flights illustrated above represent the most frequently demanded designs in the industry and are by no means the only available styles. The T and BT style flights are used for horizontal through slight incline applications, normally between 0° and 10°, while the U-flight can be used for horizontal/incline combinations through approximately 25°. The modified BT, O, OO, and OO with filler plates are utilized in horizontal/inclined applications through 90°(vertical).
