The new Doherty dualock mechanical coupler is the most advanced yet simplistic mechanical coupler on the market today. Designed for mini excavators from 0.9 – 3.5 tonne weight class, the patented dualock mechanical is world leading in regards to safety and features and it has been accomplished with minimal parts ensuring many hours of trouble free operation.
