Abstract
An apparatus for manipulating horizontal impactor hammers includes a crossbeam and a pair of depending lift arms, each lift arm having a corresponding pivot arm configured to be secured to respective ends of the hammer and to pivot about the lift arm. Once the pivot arms are attached to the ends of the hammer, the crossbeam is elevated, withdrawing the hammer from the rotor and causing the hammer to invert about the pivot axis for reinsertion into the rotor. Provisions are also made for rotating the withdrawn hammer about a vertical axis.
