Burquip Ball Coupler Delta 3,500kg

Deliver controlled overrun braking deceleration and heavy-duty towing stability for maximum-capacity commercial transporters, plant equipment haulers, and large multi-axle trailers with the Burquip Ball Coupler Delta 3,500kg. Built around the heavy-duty KNOTT mechanical overrun braking system for A-frame (Delta) drawbars, this robust assembly integrates an internal hydraulic shock damper, handbrake lever, and heavy-duty 50 mm cast ball hitch head to manage gross vehicle masses from 3,000 kg up to 3,500 kg under rigorous commercial towing conditions.

Key Features & Benefits:

• 3,000 kg to 3,500 kg Overrun Braking Capacity: Calibrated specifically for high-capacity braked trailers operating up to the maximum 3,500 kg Gross Vehicle Mass (GVM) limit, delivering smooth, proportional overrun brake actuation without surging or shoving the towing vehicle.

• Delta (A-Frame) Chassis Geometry: Features a heavy-gauge Delta housing profile engineered to bolt directly across converging A-frame drawbar members, ensuring maximum lateral rigidity and balanced distribution of towing and dynamic braking loads.

• Heavy-Duty 50 mm Ball Coupling Head: Equipped with a high-capacity cast-steel ball socket (Socket Code: CBKBALL60) compatible with standard 50 mm tow balls, featuring an ergonomic latching handle with a positive safety catch to eliminate accidental decoupling.

• 150 kg Static Nose Weight Rating: Engineered with a maximum static vertical nose load capacity of 150 kg, accommodating the heavier tongue weights common to loaded plant, machinery, and equipment trailers.

• Internal Overrun Hydraulic Damper: Houses a calibrated heavy-duty hydraulic shock absorber within the sliding shaft 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 detaches from the towing vehicle.

• Rugged Heavy-Duty Construction: High-tensile steel housing and precision-machined sliding components treated with a protective anti-corrosion coating to withstand rough site environments, mud, stone chipping, and continuous outdoor use.
