Abstract

See full text

A thumb body is pivotally connected to a first mount, and a stiff-arm anchor is connected to and extends between the first mount and a second mount. The stiff-arm anchor is selectively removable from the first and second mounts. A stiff-arm support link includes a first end connected to the thumb body and a second end connected to the stiff-arm anchor. The thumb can be converted from a hydraulic mode to a stiff-arm or fixed mode by disconnecting the first end of a hydraulic cylinder actuator from the thumb body and disconnecting the second end of the hydraulic cylinder actuator from the second mount, and by installing the stiff-arm anchor and stiff-arm support link.
