The PowerWedge Coupler for excavators comes in both hydraulic and manual models. The hydraulic model requires only 30 seconds to change attachments from the cab. With the manual version, it takes 10 minutes to change attachments. The coupler does not significantly increase tip radius, according to the company. Safety hooks prevent accidental loss of attachments.
