Mechanical quick couplers

We offer two mechanical couplers, Pro-Lok (generic) or Safelock (dedicated).  Both are available for 3/4 to 8 tonne machines.  If you need help deciding which is the best option for you, please call (01603) 403099 and speak to a member of our team who will be happy to advise you. Both Pro-Lok and Safelock are available as Tilt Couplers.

Hydraulic Couplers

A lot of time and research went into making our Uni-Lok® hydraulic quick hitch, the best coupler on the market. We offer a full fitting service or can provide you with a comprehensive kit for you to self-fit. Uni-Lok is also available as a Tilt Hitch.

“We have just added a Harford Pro-lok hitch to our Volvo E27. We have also run a wedgelock on the Takeuchi TB016 for 2 years – Harford Quickhitches are clearly best on the market”
