Patent ID: 8333102

Claim:
An assembly for actuating a pipe expander, the assembly comprising: a first actuator selectively engaging a pipe expander head and selectively actuating the pipe expander head; and a second actuator, spaced apart from the first actuator and operatively engaged with said first actuator, such that operation of the second actuator effects operation of the first actuator to actuate the pipe expander head, the first actuator having a first piston located within a first cylinder, a movement of the first piston with respect to the first cylinder actuating the pipe expander head, and the second actuator having a second piston located within a second cylinder, wherein the first actuator and second actuator are operatively engaged such that movement of the second piston with respect to the second cylinder effects movement of the first piston with respect to the first cylinder; wherein the second actuator operatively engages the pipe expander and actuation of the pipe expander causes movement of the second piston with respect to the second cylinder.
