Pintle Hooks, Ring Couplings and Combination Hitches

What is a Pintle Hitch?

A pintle hitch is a corrosion resistance hook and coupling connected to a heavy-duty tow bar and used by military and trucking companies. Pintle towing hitches is robust for extreme terrains.

Now available at wholesale prices to dealers and resellers. Suppose this sounds like you, please don’t hesitate to contact us to discuss wholesale prices. Not open to the public.

The CRN on the invoice is your guarantee of compliance with D.O.T. regulations.

For example, testing equipment like 10t Gooseneck auto-lock coupling and heavy-duty 3″ tow balls is where the engineering starts.  As a result of testing, D-Values and V-Values are obtained to satisfy your engineer’s inspection requirements.

Pintle Hook Damage

Pintle hook trailer hitch undergoes rigorous testing to ensure manufacturing integrity.

As a result of extensive testing, we found that a variety of driver errors cause pintle hook damage. They include:

• Reversing into the trailer ring coupling causes the top locking mechanism to twist or break.
• Reversing a vehicle and trailer at a sharp angle, causing the bottom of the hook to jackknife.
• Towing with a coupling head weight above 7%. – This is too heavy for tandem trailers.
• Hitch ball breakage is caused when the towing vehicle tow ball hits the trailer coupling.

It is an excellent idea before installing a new trailer hitch mount to weigh your rig on a weighbridge to calculate the towing capacity.

Disconnecting the trailer hitch is necessary when obtaining an accurate trailer towing weight. You can then configure the correct head weight for connection to the vehicle tow bar.

Tow Ball Hitches and Receiver Kits

Important: We recommend offroad couplings of all brands use a solid cast receiver hitch. Hollow receivers have a welded tongue that distorts in extreme offroad conditions and under shock loading events on the highway.

Couplemate manufacturers a range of cast tow bar receivers and hitches in Australia and tested to Australian road conditions.

Vehicle Inspections

If any questions arise from your engineer or Heavy Vehicle Inspection Officer, show the officer your invoice.

Furthermore, the Inspecting Officer may need to copy your invoice to follow up on non-compliant equipment. The easiest way to copy an invoice is to take a photo with your mobile phone.

Finally, excessive tongue weight causes light steering and lifts the vehicle headlights into oncoming traffic. Clearly, the excessive tongue weight is a safety hazard.
