YOKE runs a strict production facility, with a huge emphasis on quality control & safety at every stage of the manufacturing process, from raw materials to the completed product for the end-user.

YOKE is an ISO 9001 certified company and has Type Approval by the major international authorities from SABS, ZU, ABS, API, and DNV. YOKE has achieved CNLA certification – Chinese National Laboratory Accreditation which ensures a quality research and development (R&D) department and unsurpassed product engineering.

Magnaflux Crack Detection:
All forged components, each individually magnaflux detected after heat treatment.
Proof Load Testing:
Chain and components are proof load tested at 2.5 times the Working Load Limits with resultant permanent deformation within 1%.
Dynamic Fatigue Testing:
Batch samples of chain and components are Dynamic Fatigue Tested at 1.5 times Working Load Limit for 20,000 cycles.
Ultimate Breaking Load Testing:
Batch samples are Break Load Tested in a static tensile testing machine to ultimate failure. The minimum ultimate force is equal to the Working Load Limit times the safety factor.
Spectrographic Analysis:
To assure of the proper metallurgy content of all raw materials.
Eddy Current Detection:
All load pins are 100% individually inspected after heat treatment.
