About hydraulics

Hydraulic excavator couplers are designed to replace mechanical quick hitches on your excavators, making it quicker, easier and safer to swap attachments.

They are simply another way to couple attachments, like buckets, with excavators and earthmovers. A hydraulic coupler uses a hydraulic mechanism to couple with the attachment which can be operated from the excavator cab automatically.

Uni-Lok® is Harford’s hydraulic coupler solution. The innovative design incorporates a number of key unique safety features including a double-locking mechanism.  When combined with the Harford premium build-quality the result is a highly durable, long-lasting hydraulic coupler which is easy to install, operate and maintain.

Machine downtime is significantly reduced as attachments are changed quickly from the convenience of the cab using a simple switch operation.  Two highly visible indicators give the operator complete confidence that the Uni-Lok® is fully engaged with the attachment and safe to work.
