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.
