Excavator quick coupler PosiGrab™

The ESCO PosiGrab hydraulic quick coupler was designed and developed to provide simplified use for the machine operator and to optimize site safety. ESCO attachments are known for productivity and safety, and the PosiGrab coupler continues that tradition. The PosiGrab hydraulic coupler features: Front and rear attachment pins that are mechanically locked independently through the full working cycle and are independently released with hydraulics The natural position of the coupler is locked and only opens using forced hydraulic pressure All operations to pick-up or release attachments are done without leaving the safety of the cab, including visual confirmation that the front and rear locking mechanisms are properly engaged
