Description
Overview:
This Overrun Brake Coupling Assembly, Pressed Delta, 2700 kg (MPN 764 174) is a complete AL-KO overrun device for braked A-frame (delta) trailers. Built around the AL-KO 251S overrun unit with a pressed steel body, it manages the trailer's braking automatically under deceleration, helping to reduce snatch and improve stability. Supplied with an AL-KO AK301 50 mm ball coupling head pre-fitted, it is suitable for standard 50 mm towballs used across the UK and Europe. The 2,700 kg gross trailer weight rating (approximately 2.7 tonnes / 5,950 lb) makes it appropriate for a wide range of braked trailers within this capacity. Designed for durability in fleet and site use, the assembly provides a robust connection between the tow vehicle and trailer while transmitting overrun forces to the trailer brake linkage. It is intended for bolt-on installation to a delta (A-frame) drawbar where an AL-KO 251S pattern overrun device is specified.
Key Features:
- Rated for 2,700 kg gross trailer weight (approx. 5,950 lb)
- Pressed steel delta (A-frame) overrun brake coupling construction
- Supplied with AL-KO AK301 50 mm ball coupling head, pre-fitted
- AL-KO 251S overrun device for braked trailer applications
- Integrated overrun damper for smoother, progressive braking response
- Compatible with standard 50 mm towballs used in the UK/EU
- Pre-assembled coupling and head to simplify installation
Typical Applications:
For use on braked A-frame (delta) trailers up to 2,700 kg GVW, including general duty, plant and equipment transport, car transporters, box and utility trailers. Suitable where an AL-KO 251S style overrun device with a 50 mm ball head is required. Commonly used by fleet operators and trailer builders needing an overrun coupling assembly matched to AL-KO brake linkages.
