Abstract
A fastener installation tool includes a nose assembly, first and second cylinders, first and second pistons, and a yoke. The nose assembly is adapted to apply an axial load to a fastener along a longitudinal axis of the nose assembly. The first and second cylinders are diametrically opposed to one another with respect to the longitudinal axis of the nose assembly. The first piston is disposed within the first cylinder and is movable along a longitudinal axis thereof. The second piston is disposed within the second cylinder and is movable along a longitudinal axis thereof. The yoke connects the first piston, the second piston, and the nose assembly such that motion of one of the pistons along its corresponding longitudinal axis causes motion of the other one of the pistons along its corresponding longitudinal axis and motion of at least a portion of the nose assembly along its longitudinal axis.
