How To Use Safety Chains?

Safety chains, as one of the most important parts of a trailer, are essential for safe towing of a trailer. As the name implies, a safety chain is a chain that links the trailer’s drawbar and the towing vehicle to ensure that the trailer is properly connected to the towing vehicle.

How should safety chains be used with a trailer hitch ?

1. Two safety chains are required, choose the safety chains of the correct length, cross the safety chains under the hook and coupler, and flow out enough slack to turn and tow the towing rope when the trailer is loose.
2. During connecting the trailer, make sure that the chains are connected to the emergency brake box , also the chain is shorter than the trailer safety chain. If the chain connected to the emergency brake box is longer than the safety chain, the brake box will not start.
3. Before moving the trailer, pls make sure that the safety chain is fixed to the towing vehicle. Stop and check regularly during towing.
4. Regularly check the chains and hooks for wear or damage, and replace any worn or damaged chains and hooks before towing again.
5. Check your safety chain for the correct classification for the gross vehicle weight rating (GVWR). The strength rating (minimum breaking force) of each section of safety chain or its equivalent and its attachments must equal or exceed the GVWR of the trailer.
6. Stop and check the chain regularly, replace any worn safety chains, and never drag the safety chain while driving.
