Related Product
A safety chain is a type of welded chain designed to provide additional security. Typically made as a straight link chain, it serves as an auxiliary to the primary connection device, preventing accidental detachment or disconnection. Its main function is to act as an emergency connection safeguard in trailers, boats, door locks, or industrial equipment, ensuring that equipment or cargo remains secure at all times.
Tuohai offers safety chains in various materials and specifications, including options tailored for trailers, marine use, industrial applications, and door locks. For more details, please visit the Tuohai website.
While high carbon steel has high strength, it also has high brittleness, making it prone to breakage under heavy loads or impact. Additionally, its poor weldability can lead to cracks after welding, increasing potential safety hazards. Therefore, high carbon steel is unsuitable for safety chains requiring high reliability.
afety chains serve as a backup connection, taking on emergency loads if the primary connection fails.
Trailer Safety Chains: Maintain the connection between the trailer and towing vehicle in case of a hitch failure.
Boat Safety Chains: Ensure stability during transportation or mooring.
Usage Steps:
Secure one end of the chain to the fixed point on the towing vehicle or equipment.
Connect the other end to the hook of the towed vehicle or boat.
Ensure the chain length is appropriate—neither dragging on the ground nor hindering the equipment’s turning radius.
Tuohai provides various hooks and connection accessories for easy installation and use.
The length of trailer and boat safety chains should be adjusted according to the equipment size and towing distance:
Trailer Safety Chains: Should be long enough to allow maximum turning without hindrance, but not so long that they drag on the ground.
Boat Trailer Safety Chains: Should remain moderately taut during use to prevent swinging or collisions caused by slackness.
If you’re unsure about the required length, contact Tuohai, and our engineers will recommend the appropriate specifications.
The size of safety chains depends on the equipment’s gross weight, environmental conditions, and standards. Chains must also match the towing or equipment hooks to ensure secure connections.
Trailer Safety Chains: Must meet at least 1.5 times the gross trailer weight (GVWR) in working load capacity. Common grades include G30, G43, and higher-strength G70 chains.
Boat Safety Chains: Stainless steel chains with superior corrosion resistance are recommended for wet or saltwater environments.
Tuohai provides safety chains in various sizes for light to heavy-duty equipment. Contact Tuohai for more information.
Trailer safety chains can be extended using connectors or hooks, but the added section must have a strength equal to or greater than the original chain to avoid weak points. We recommend using Tuohai’s Safety Chain Hook Set and high-strength connectors to ensure the reliability and safety of the extended chain.
