What is a safety carabiner? Applications of safety carabiners

Safety carabiners are critical protective devices that ensure the safety of workers when operating at heights or in hazardous industrial environments. This product not only connects securely to safety harnesses but also supports efficient cargo lifting. Let’s explore safety carabiners and protective solutions from Naltako in detail through the article below.

What is a Safety Carabiner? What are its Practical Applications?

A safety carabiner is a protective accessory used to connect safety harnesses, cables, or chains, ensuring worker safety during high-altitude operations or cargo transport using cranes. This device is designed with automatic screw gates or snap hooks to prevent fall risks, complying with OSHA safety standards. Safety carabiners are widely applied in:

• Construction: Protecting workers during scaffolding operations.
• Electric Power: Supporting technicians working on utility poles.
• Rescue: Ensuring safety in mountain climbing and rescue missions.
• Manufacturing and Maintenance: Connecting harnesses when repairing machinery.
• Cargo Lifting: Supporting mini cranes or hydraulic pallet jacks.

Which Safety Carabiner Material is Best?

Safety carabiners are made from common materials such as:

• Stainless Steel (SUS 304): Superior corrosion resistance, load capacity from 60kg to 500kg, suitable for humid or chemical environments like coastal projects.
• Galvanized Steel: Affordable and good load capacity but less rust-resistant, suitable for dry environments like warehouses.
• Aluminum Alloy: Lightweight, load capacity from 60kg to 350kg, convenient for rescue or high-altitude maneuvers, but more prone to wear than stainless steel.

SUS 304 stands out due to its high durability, exceptional corrosion resistance, and surface treatment using strong oxidation technology, making it heat-resistant and suitable for harsh environments. Meanwhile, aluminum alloy carabiners are 20% lighter than stainless steel, making them ideal for rescue. Depending on the environment, Naltako suggests choosing SUS 304 for long-term durability or aluminum alloy for portability.

What is the Maximum Load Capacity of a Safety Carabiner?

Safety carabiners have diverse load capacities, ranging from 60kg to over 500kg depending on design and material:

• Snap hooks: Load capacity of 60-150kg, suitable for personal safety harnesses.
• D-ring stainless steel carabiners: Load capacity of 150-350kg, used in construction and power sectors.
• Multi-purpose carabiners: Load capacity up to 500kg, supporting cargo lifting with mini cranes.

Diameter sizes from 2mm to 10mm directly affect the load capacity. Choosing a safety carabiner that matches the load requirements is a key factor in ensuring labor safety.

How to Use Safety Carabiners Correctly to Avoid Danger?

To use safety carabiners effectively and avoid danger, the following steps should be followed:

• Pre-use Inspection: Ensure the automatic screw gate, spring gate, or snap hook is not worn or rusted.
• Proper Installation: Connect the safety carabiner to the safety harness or cable, and check for stability before starting work.
• Adhere to Load Limits: Do not exceed the rated load capacity; for example, a 200kg D-ring carabiner should only be used for one person.
• High-altitude Operation: Ensure no one stands under the load and use additional fall arrest lanyards when working on scaffolding.
• Avoid Common Errors: Do not use the wrong load capacity, do not skip gate checks, and do not use damaged products.

OSHA Safety Standards for Fall Arrest Carabiners

OSHA standards (Lockout/Tagout – LOTO) and international CE certification regulate that safety carabiners must ensure load-bearing capacity, anti-disconnection, and durability in harsh environments. FDI enterprises and large construction sites prioritize products meeting these standards due to:

• Optimal Safety: Safety carabiners with automatic screw gates, bearing loads from 60kg to 500kg.
• Maintenance Control: Multi-functional design with nine holes allowing multiple people to lock out simultaneously.
• High Durability: Strongly oxidized surfaces, corrosion-resistant and heat-resistant, suitable for chemical environments.
