Abstract

An apparatus for removing a wheelset from a railroad vehicle includes a frame configured for motion with respect to the railroad vehicle. The apparatus also includes a lifting yoke cooperatively associated with the frame. The yoke is configured to engage flanges of the wheelset. The apparatus further includes at least one lifting screw interposed between the frame and the lifting yoke, such that upon rotation of the at least one lifting screw, the yoke may be raised and lowered to selectively engage the flanges of the wheelset. A “universal” lifting yoke can include a first portion which engages the at least one lifting screw, a set of extendable transverse members having outward ends, and flange-engaging blocks secured to the outward ends of the extendable transverse members and configured to engage the flanges of the wheelset. The extendable transverse members and the flange-engaging blocks can be cooperatively configured and dimensioned to engage substantially all anticipated wheelsets expected to be encountered in a given application. The “universal yoke” can be employed with screw-actuation, or with other types of actuating members.
