Classification: CPC B | IPC B

Claim 0:
1. A hydraulic tool comprising:
a working head interchangeable with a plurality of types of working heads capable of performing different tasks, the working head comprising an impactor and head indicia that identify the type of the working head;
a tool frame having a piston;
a hydraulic system coupled to the piston, wherein the piston moves in a distal direction when the hydraulic system is actuated;
a coupling mechanism comprising a first interlocking structure on the tool frame including a T-shaped slot and a second interlocking structure on the working head including two arms connected with the head and extending in a proximal direction, wherein the arms form a T-shaped cross section sized to slide into the T-shaped slot, wherein the arms extend from the working head separated from one another by a gap between the arms extending a full width of the arms in a first direction perpendicular to the distal direction, wherein the head indicia are disposed on a surface of the working head adjacent to the gap, wherein the coupling mechanism releasably couples the working head to the tool frame and releasably couples the piston to a working surface of the working head, wherein engagement of the first structure with the second structure removably connects the working head with the tool frame and engages the piston with the impactor, wherein the first and second structures engage with one another by sliding the arms into the slot in the first direction;
a head sensor, the head sensor being adapted to detect the head indicia, wherein the head sensor is disposed on a surface of the tool frame adjacent to the T-shaped slot; and
a controller connected with the head sensor and the hydraulic system, wherein, when the working head is engaged with the tool frame, the head sensor detects the head indicia,
wherein the controller receives a signal generated by the head sensor in response to the head indicia, determines the type of the head, determines a maximum force to apply to the working surface based at least in part on the determined head type, and controls the hydraulic system to apply the maximum force.
