Description
Overview:
This overrun coupling handbrake lever (MPN 764 139) is a replacement control handle for AL-KO 90S/R, 120SR and 121SR braked trailer couplings. It is designed to apply and hold the trailer's parking brake via the coupling's ratchet mechanism, restoring positive handbrake action when the original lever is worn, bent or damaged. The lever mounts on the coupling body at the standard pivot and works with the existing ratchet quadrant and brake linkage to engage the trailer brakes for parking and maintenance checks. Manufactured in robust steel for workshop and fleet use, it is suitable for a wide range of light commercial trailers, plant and equipment transporters, goods trailers and caravans that are fitted with the listed AL-KO overrun couplings. Replacing a tired lever helps ensure reliable parking brake performance and safe trailer holding on level ground and ramps.
Key Features:
- Compatible with AL-KO 90S/R, 120SR and 121SR overrun couplings
- Replacement handbrake lever to restore positive parking brake operation
- Steel construction for durability in fleet and site environments
- Interfaces with the coupling's existing ratchet and brake linkage
- Direct-fit to standard coupling mounting points (no modification to the coupling body)
- Trade-quality service part for trailer maintenance and refurbishment
- Suitable for braked trailers using the listed AL-KO coupling families
- Helps maintain safe trailer parking and brake check procedures
Typical Applications:
Used on the overrun coupling assembly of braked trailers to manually apply and hold the parking brake. Typical installations include plant and machinery transporters, general-purpose goods trailers, car and equipment carriers, box trailers and caravans fitted with AL-KO 90S/R, 120SR or 121SR couplings. Commonly fitted during coupling overhauls or when the original lever has excessive play or damage affecting ratchet engagement.
