    摘要： A hydraulic cylinder may include a cylindrical body, a first piston rod coupled with a first end of the body, and a second piston rod coupled with a second end of the body. The first piston rod may include a cavity with an inner diameter, and the second piston rod may have an outer diameter that is smaller than the inner diameter of the cavity. The hydraulic cylinder is adjustable from a closed position, in which a length of the first piston rod is housed inside the body and a length of the second piston rod is housed inside the cavity of the first piston rod, to an extended position, in which the first piston rod extends through the first end of the body and the second piston rod extends through the second end of the body.

    摘要： Reciprocally moving an output rod mounted to a force transfer member includes applying hydraulic pressure to a first piston and cylinder device to operate the first piston and cylinder device in compression to move the force transfer member in a first direction; applying hydraulic pressure to a second piston and cylinder device to operate the second piston and cylinder device in compression to move the force transfer member in an opposite second direction; refraining from applying tension to the second piston and cylinder device while applying hydraulic pressure to the first piston and cylinder device; and refraining from applying tension to the first piston and cylinder device while applying hydraulic pressure to the second piston and cylinder device.
