AL-KO Kober Ball Coupler Delta 3,000kg

Provide heavy-duty overrun braking control and structural towing integrity for commercial transporters, large livestock trailers, and heavy tandem-axle caravans with the AL-KO Kober Ball Coupler Delta 3,000kg, distributed by Burquip. Engineered by AL-KO Kober (Model 251G series fitted with the AK 301 cast coupling head) for A-frame (Delta) drawbars, this mechanical overrun assembly combines a hydraulic shock damper, handbrake lever, and positive-locking 50 mm ball hitch head to manage gross trailer masses from 1,550 kg up to 3,000 kg under intensive commercial duty cycles.

Key Features & Benefits:

• 1,550 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, providing proportional overrun braking action without surging or shoving the towing vehicle.

• Delta (A-Frame) Chassis Geometry: Features an engineered Delta housing profile designed to mount directly over converging A-frame drawbar beams, distributing longitudinal pull and vertical tongue loads evenly into the trailer frame.

• AK 301 Cast Ball Coupling Head: Equipped with AL-KO's heavy-duty AK 301 cast-steel coupling head compatible with standard 50 mm tow balls, featuring an ergonomic handle with an integrated safety lock and visual wear/coupling indicator.

• Integrated Hydraulic Overrun Damper: Houses a calibrated internal hydraulic shock absorber that softens push-pull transitions during stopping and accelerating, eliminating harsh jerking and brake snatch.

• Spring-Assisted Over-Centre Handbrake: Fitted with an over-centre parking brake lever with a ratchet mechanism to reliably hold the 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 should the trailer detach from the towing vehicle.

• Corrosion-Resistant Heavy-Gauge Construction: Fabricated from high-tensile cast and pressed steel treated with protective zinc galvanising to withstand continuous road spray, mud immersion, and stone chipping.
