Corporate Sustainability Rreport


Product Regulations

After design and development are completed according to suitable product regulations that are selected reflective of the characteristics of products, offshore energy, construction, material handling, and mining-oriented Grade 80/100 chains, steel wire ropes, and webbing accessories, wire rope terminal sockets, shackles, yellow snatch blocks, and personal safety harness fittings are designed, developed and manufactured.

As is required by regulations, applications are filed with the following certifying bodies to have the mechanical testing (pulling force) completed for products in respective series in order to ensure that products meet regulatory requirements and the needs of customers:

  • Canadian Standards Association


  • Det Norske Veritas


  • American Bureau of Shipping


  • German Social Accident Insurance Association

    (DGUV Test)/CE0299

  • Shoe and Allied Trade Research Association


  • Societe Generale de Surveillance


Product Testing Verification

Product safety regulations promoted by related international organizations have always been the focus of attention for YOKE. As such, the Product R&D Dept maintains optimally interaction with said respective organizations. In addition, there is rigid internal control over the versions of international standards so that the Product R&D Dept can keep track of related information as soon as the regulations are added or revised.

For products in the N series that may be sold directly, we are capable of having 100% of the products complete relevant testing before a customer places a purchase order in order to meet the customer’s needs. For parts and components that are terminal products, however, there is no testing and verification mechanism available as they are sent for testing and verification by the customer after they are assembled as the final product.  For the 8 series of products, on the other hand, the needs for product qualification are tested and verified according to market sales and customer requirements. Among the 12 major categories, 4 are 100% sent for testing and verification while another 4 are tested based on the customers’ actual needs. Analysis of our 2018 revenue shows that the 4 major categories that are 100% sent for testing and verification accounted for up to 91.62% of the 8 series of products (1.96% increase compared to 2017) and also over 80% in the past 5 years. This indicates that product safety qualification is highly emphasized by customers.

In order to ensure safety and protection of users, in addition to related quality management systems, factory qualifications, and product qualifications mentioned above, YOKE has had its products covered by liability insurance, with the insured value up to USD 5 million for more than 10 years, which offers additional protection to the users. No product safety-related events that resulted in an undermined corporate image of YOKE occurred in 2018.

Change of standards

External product standards are critical documentations that YOKE takes great pains to comply with. Presently, our 8 series products are compliant with 56 product standards; N series and SRL products conform to 21 standards along with 21 systems and testing standards. Certain policymakers would also approach YOKE's Product R&D Dept for opinions on whether the revised contents are feasible before making the actual change.

Responsible QA personnel from Quality Assurance Dept are required to review pertinent laws, regulations, and standards on a quarterly basis (or prior to external audits) to ensure that such laws/regulations/standards are up to date. In the event of a change in external standards, the Product R&D Dept is required to compile a difference analysis report that identifies and assesses risks to the quality of products manufactured. After carrying out relevant tests on the specifications that have been changed as required by the standard, the department then needs to explain to the Product Center, the Product R&D Deptt and manufacturing-related personnel about the changes involved in order to mitigate the impact of changes on the Company and its products.

YOKE is a manufacturer of industrial lifting equipment and safety protection equipment, which is why the Product Development Department always discusses with responsible departments on the technicalities of product design and manufacturing, and verifies the feasibility of proposed changes before amending product specs or proceeding with new product design/development or design changes.

Laboratory Establishment

YOKE's laboratory has been established for more than 10 years, and the Company continues to test its products and calibrate the laboratory in accordance with ISO 17025 laboratory quality management system. In order to improve the accuracy and credibility of our lab results, we have initiated our ISO 17025 certification for our laboratory in 2018 and we are scheduled to complete our certification in mid-2019. With product safety in mind, the laboratory continues to explore advanced technologies and new equipment, and performs multiple tests in accordance with international standards in order to ensure the quality and safety of products delivered to users. We are planning to introduce projection image storage equipment at the laboratory in 2019 to operate in conjunction with the product lifecycle management (PLM) that was introduced in 2018 to assist with the management of material receiving by means of quick analysis for NG items. Presently, tests we can perform at our laboratory include tension test, drop test and salt spray test.
