What Does “Compliance” Really Mean in the World of Lifting?
Every day, across mining, industrial and construction zones, tons of material hang suspended by lifting components. In this safety critical environment, “compliance” isn’t just an industry buzzword or a checkbox for safety auditors, it is the line between a seamless operation and a catastrophic failure.
To achieve true safety and legal certainty, we must look beyond the terminology and understand what compliance demands in practice.
The Legal Foundation: Driven Machinery Regulations
First and foremost, industry is guided by the requirements of the Driven Machinery Regulation 18 under the Occupational Health and Safety (OHS) Act, which mandates that:
"Every item of lifting tackle is well constructed of sound material, is strong enough and is free from patent defects and is in general constructed in accordance with a generally accepted technical standard."
When considering standards within the South African context and focussing on chain product, two primary standards apply to chain manufacturing:
SANS 189: South African National Standard – Short link Chain Medium Tolerance
SANS 251: South African National Standard – Long-link and Extra-long-link medium tolerance steel chains for general purposes
The 4 Pillars of Chain Compliance
To verify full compliance, every product must satisfy four core technical requirements established by these SANS standards:
Chain Dimensions
Mechanical Properties & Strength
Steel Chemistry
Product Markings & Traceability
A product is only truly certified and compliant when all four of these requirements are fully met. Failing even a single criterion compromises the integrity of the entire system.
Understanding the Risks of Non-Compliance
1. Chain Dimensions
Inferior or inconsistent chain dimensions directly undermine a chain’s overall strength. For instance, if a high-grade chain is manufactured using a rod diameter smaller than prescribed by the standard, manufacturers often alter heat treatment processes to meet minimum strength requirements. This creates a brittle product highly prone to sudden failure when subjected to unexpected shock loads or overloads.
2. Chain Strength & Mechanical Properties
Chains with inferior mechanical properties fail to meet the mandatory 4:1 or 5:1 factor of safety clearly stipulated in the Driven Machinery Regulations and SANS standards. Without this safety margin, catastrophic failure can occur.
3. Steel Chemistry
Chemical composition is critical when producing high-grade, safety-critical chains. Lacking the precise alloy content specified by SANS standards can severely diminishes a chain's toughness, overall tensile strength, and resistance to strain-age embrittlement over time.
4. Product Markings & Traceability
Beyond SANS requirements, ISO 9001:2015 emphasizes the vital importance of product traceability. Traceability relies on a unique batch number or code assigned to a specific manufacturing run. Compliant chains must clearly display:
A unique batch code
The grade code
The manufacturer’s name or brand
Without clear, permanent markings, end-users cannot verify whether a chain is suitable for a specific lifting application. Using untraceable equipment exposes operations to severe legal liabilities and unnecessary safety hazards.
Shared Responsibility: The Final Link
While chain manufacturers are strictly bound to technical standards, the responsibility does not stop at the factory door. End-users carry a direct obligation under Driven Machinery Regulation 18 to ensure all equipment deployed on site meets full statutory compliance.
Prioritize vendor accountability, insist on full batch documentation, and never treat compliance as an afterthought. Protecting your team, your cargo, and your business begins with choosing certified, fully traceably marked equipment every single time.
