Burquip Ball Coupler Delta 1,300kg

Deliver controlled overrun braking performance and towing stability for light-to-medium trailers, camp haulers, and compact touring caravans with the Burquip Ball Coupler Delta 1,300kg. Built around the KNOTT mechanical overrun braking system for A-frame (Delta) chassis designs, this pressed-steel overrun assembly combines an internal hydraulic shock damper, an over-centre parking handbrake, and a positive-locking 50 mm ball hitch head to provide proportional braking deceleration for trailers with an operational gross weight rating spanning 750 kg to 1,400 kg (nominally designated at 1,300 kg).

Key Features & Benefits:

• 750 kg to 1,400 kg Braked Operating Range: Calibrated specifically for light-to-medium single-axle braked trailers (nominal 1,300 kg GVM), actuating mechanical drum or disc brakes proportionally to tow-vehicle deceleration to eliminate trailer pushing and nose dive.

• Delta (A-Frame) Chassis Mount: Engineered with a pressed-steel Delta housing profile designed to bolt across converging A-frame drawbar beams, ensuring optimal structural distribution of dynamic pull forces and nose loads into the chassis rails.

• Standard 50 mm Ball Coupling Head: Equipped with a precision ball socket head (Socket Code: CBKBALL45A) matching standard 50 mm tow balls, featuring an ergonomic latching handle with a built-in safety catch to eliminate accidental disconnection.

• Internal Overrun Hydraulic Damper: Houses a calibrated internal hydraulic shock absorber that softens stop-start transitions, preventing harsh jolting, jerking, and brake snatch during sudden deceleration.

• Spring-Assisted Over-Centre Handbrake: Fitted with an over-centre parking brake lever with a ratchet mechanism to mechanically lock trailer brakes securely when parked on 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.

• 100 kg Static Vertical Load Rating: Certified to carry a maximum static nose weight of up to 100 kg at the coupling point.

• High-Speed Classification: Certified under Burquip’s braked high-speed coupling category, designed to handle sustained highway towing speeds with stable tracking.
