Burquip Ball Coupler Mono 80x80 3,000kg

Deliver controlled overrun braking deceleration and heavy-duty towing stability for heavy commercial trailers, plant transporters, and large touring caravans with the Burquip Ball Coupler Mono 3,000kg. Engineered around the proven KNOTT mechanical overrun braking system for straight central drawbars (Mono / single-pole chassis configurations), this heavy-duty assembly sleeves directly over 80 × 80 mm square hollow sections (SHS). It integrates a hydraulic damper, handbrake lever, and positive-locking 50 mm ball coupling head to provide proportional braking deceleration for trailers with a gross vehicle weight ranging from 1,600 kg up to 3,000 kg.

Key Features & Benefits:

• 1,600 kg to 3,000 kg Braked Capacity: Calibrated for medium-to-heavy single- and tandem-axle trailers with a Gross Vehicle Mass (GVM) up to 3,000 kg, actuating mechanical brakes proportionally to tow-vehicle deceleration without surging or shoving the tow vehicle.

• Mono 80 × 80 mm Chassis Mount: Engineered to sleeve directly over 80 × 80 mm square central drawbars, ensuring rigid mechanical alignment and high beam strength for single-pole drawbar architectures.

• Standard 50 mm Ball Coupling Head: Equipped with a precision-cast 50 mm ball hitch head compatible with standard tow balls, complete with an ergonomic safety latch handle to prevent accidental decoupling in transit.

• Internal Overrun Hydraulic Damper: Houses an internal hydraulic shock absorber within the sliding drawshaft that cushions push-pull transitions during stop-start driving, 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.

• Heavy-Duty Construction: High-tensile cast and fabricated steel housing treated with a protective anti-corrosion finish to withstand rough gravel road vibrations, road spray, mud, and harsh outdoor environments.
