Abstract:
A fluid-powered tool assembly, usable with a support platform having an arm, the tool assembly comprising:a first tool member pivotally connectable to the arm for rotation about a first axis; a second tool member positioned to cooperate with said first tool member; a body having a longitudinal axis and an end portion, said end portion having one of said first and second tool members attached thereto for movement with said body, one of said first and second tool members further including a support housing sized to receive at least a portion of said body therein and support said body, said support housing being a support tube; an output shaft rotatably disposed within said body in general alignment with said body axis for rotation about a second axis spaced apart from said first axis, said shaft having a shaft end portion, with the other of said first and second tool members attached thereto for movement with said shaft; and a linear-to-rotary force transmitting member mounted for longitudinal movement within said body in response to selective application of pressurized fluid thereto, said force transmitting member engaging said body and said shaft to translate longitudinal movement of said force transmitting member into rotational movement of said shaft relative to said body, said first and second tool members being rotatable relative to each other about said second axis by operation of said force transmitting member and said first tool member pivotal connection to the arm allowing rotation of the tool assembly as a unit about said first axis, said force transmitting member being operable to rotate said first and second tool members about said second axis independent of rotation of said first tool member about said first axis.
