Burquip Eye Coupler Delta 3,500kg

Deliver controlled overrun braking deceleration and heavy-duty articulation for maximum-capacity commercial plant trailers, industrial equipment transporters, and heavy agricultural rigs with the Burquip Eye Coupler Delta 3,500kg. Built around the heavy-duty KNOTT mechanical overrun braking system for A-frame (Delta) drawbars, this assembly replaces a conventional ball hitch with a 40 mm DIN towing eye to couple directly with commercial pintle hooks, NATO-style towing jaws, and heavy hitch pins, providing proportional braking deceleration for trailers with a Gross Vehicle Mass (GVM) ranging from 2,700 kg up to 3,500 kg.

Key Features & Benefits:

• 40 mm DIN Heavy-Duty Towing Eye: Fitted with a solid forged 40 mm DIN standard towing ring engineered for secure commercial towing connections with pintle hooks, NATO jaws, and pin-and-ball hitches.

• 2,700 kg to 3,500 kg Overrun Braking Capacity: Calibrated specifically for high-capacity braked trailers operating up to the maximum 3,500 kg GVM limit, delivering smooth, proportional overrun brake actuation without surging or shoving the towing vehicle.

• Delta (A-Frame) Chassis Geometry: Features an engineered Delta housing profile designed to bolt across converging A-frame drawbar beams, ensuring maximum lateral rigidity and balanced distribution of towing and dynamic braking loads into the chassis rails.

• Superior Rough-Site & Off-Road Articulation: The ring-and-pin interface provides wide angular deflection and rotational freedom around the towing pin, eliminating coupler binding and drawbar fatigue over severe job-site undulations, trenches, and unpaved terrain.

• Internal Overrun Hydraulic Damper: Houses a heavy-duty hydraulic shock absorber within the sliding drawshaft that cushions push-pull transitions during stopping and accelerating, eliminating harsh jerking and brake snatch.

• Spring-Assisted Over-Centre Handbrake: Features an over-centre parking brake lever with a heavy-duty ratchet mechanism to mechanically lock trailer brakes when parked on steep inclines or stored unhitched.

• Emergency Breakaway Protection: Pre-fitted with attachment points for an emergency breakaway cable, ensuring immediate, fail-safe brake engagement if the trailer separates from the towing vehicle.

• High-Speed & Heavy Commercial Rating: Certified under Burquip’s braked high-speed coupling category, designed to withstand continuous road travel as well as demanding off-highway industrial use.
