Fork chains

Applications: Automotive Industry, Construction, Food processing, Chemical Industry, Cement Industry

Fork chains

The links of the Bechtel fork chain are forged from different quality steels and then hardened or tempered in the field according to the material. In individual cases, additional partial induction hardening is carried out. Various types of plastic carriers can be mounted on the individual links and/or welded from steel.

Specifications Fork Chains

The connecting bolts are supplied as standard in the lockring version. Other bolt shapes can also be offered and supplied on request. The table below shows the fork chain in different versions with the respective breaking strength.

Embodiments

We supply the chains with custom-made carriers for horizontal, ascending and vertical conveying paths. When choosing the carriers, the conveying capacity is taken into account. Below are some examples of drop-forged chains with welded-on scrapers.
