Couplemate™ specialises in safe and secure towing equipment. The CM501, or 5T Pintle Hook, is rated to a maximum ATM of 5,000kg, depending on the towing vehicle, and has a CTA number.
Product Specifications
This pintle hook has a yellow horn and is designed to tow 75mm trailer ring couplings.
- Maximum ATM: 5,000kg
- Maximum D-Value: 36.8kN
- Component Type Approval Number: CTA-045737
- Hole Centres: 85mm x 45mm – Bolts 1/2 inch x 2.25 inch
- Minimum grade 8.8 bolt
Important: Do not use this component in any application that exceeds the specified maximum D-Value and/or ATM (Aggregate Trailer Mass). If you need a higher ATM or D-Value, you may need PINTLEHOOK-502.
Why is the D-Value important?
Towing capacity for Pintle Hooks is critical when selecting the right pintle hook, as it varies with your truck and trailer weight.
Finally, the hitch rating is a force measurement from dynamic testing (2,000,000 cycles at full load), during which maximum pressure is applied to the pintle hitch. For the Couplemate 10t pintle hook pintle ring on the right-hand side of the image, the “D-Value” is 49 kN.
Mismatched towing components wear and break prematurely.

- Install the Pintle Hook into the 85mm x 45mm hole spacings.
- Failing to select the correct D-value for your truck/trailer combination will cause excessive component wear.
Frequently Asked Questions
Two forces are acting on a pintle hook; they are
- D-value is the horizontal towing force.
- S-Value is the downward vertical force on the trailer on the tow bar.
What is a CTA Number?
Road vehicle regulation in Australia started a new era on 1 July 2021. The CRN and SARN system was replaced by the Component Type Approval to demonstrate regulatory compliance. It’s essentially a certificate.
What spare parts are available?
Each unit includes high-tensile bolts, spring washers, and nuts.

5-Tonne Pintle Hook: Operational DO’s & DON’Ts
Heavy-duty transport demands strict safety compliance. Follow these critical guidelines to ensure your 5,000kg rated pintle hook operates safely and passes heavy vehicle road inspections.
✔️ Towing Best Practices (The DO’s)
- Match the D-Value Ratings: Ensure your towbar, mounting structure, and drawbar eyelet are all rated for a 5-tonne capacity and equivalent D-Value loads.
- Use Grade 8.8 (or higher) Bolts: Secure the pintle hook with high-tensile mounting hardware (typically four M16 Grade 8.8 or Grade 10.9 fasteners) torqued to the manufacturer’s specifications.
- Insert the Safety Linchpin: Always engage the secondary safety tether pin (linchpin) after dropping the top latch over the drawbar eye; this prevents accidental decoupling on rough terrain.
- Lubricate the Pivot Point: Apply heavy-duty chassis grease to the hook’s horn and grease nipples regularly to reduce friction and wear between the hook and the trailer ring.
- Check CRN/ADR Compliance: Do verify that the component markings (such as ADR approval or Component Registration Number tags) remain clear and legible for transport authority checks.
❌ Critical Safety Risks (The DON’Ts)
- Don’t Weld the Pintle Hook Body: Never weld, modify, or heat-treat the cast or forged pintle hook body, as this alters the metallurgy and can cause sudden structural failure under load.
- Don’t Exceed Maximum Vertical Load: Never confuse the 5t maximum towing capacity with the static vertical tongue weight limit (typically significantly lower, around 2,000kg to 4,000kg).
- Don’t Tow with Excessive Wear: Never operate the hook if the throat/horn thickness has worn down by more than 10% of its original dimension; replace the hook immediately if it fails wear-gauge tests.
- Don’t Mix Mismatched Eyelet Sizes: Avoid using small or overly oversized drawbar rings; always mate the hook with a heavy-duty 2.5-inch (63.5mm) or 3-inch (76.2mm) ADR-approved towing eye.
- Don’t Tighten Safety Chains Too Tight: Never tighten your trailer safety chains so much that they restrict the pintle hitch’s 90-degree articulation and turning-circle clearance.
