Split rail trolley system

An apparatus for removing a wheelset from a railroad vehicle, said apparatus comprising:

• a frame configured for motion with respect to the railroad vehicle;
• a lifting yoke cooperatively associated with said frame, said yoke being configured to engage flanges of the wheelset;
• and
• at least one lifting member interposed between said frame and said lifting yoke, such that upon actuation of said at least one lifting member, said yoke may be raised and lowered to selectively engage the flanges of the wheelset;
• wherein:
• said lifting yoke in turn comprises:
• a first portion which engages said at least one lifting member;
• a set of extendable transverse members, associated with said first portion, and having outward ends;
• and
• flange-engaging blocks secured to said outward ends of said extendable transverse members and configured to engage the flanges of the wheelset;
• and
• said extendable transverse members and said flange-engaging blocks are cooperatively configured and dimensioned to engage substantially all anticipated wheelsets expected to be encountered in a given application.

• a frame configured for motion with respect to the railroad vehicle;
• a lifting yoke cooperatively associated with said frame, said yoke being configured to engage flanges of the wheelset;
• and
• at least one lifting screw interposed between said frame and said lifting yoke, such that upon rotation of said at least one lifting screw, said yoke may be raised and lowered to selectively engage the flanges of the wheelset;
• wherein said lifting yoke comprises a set of extendable transverse members with outward ends configured and dimensioned to engage the flanges of the wheelset.

An apparatus for removing a wheelset from a railroad vehicle, said apparatus comprising:

• a frame configured for motion with respect to the railroad vehicle;
• a lifting yoke cooperatively associated with said frame, said lifting yoke having first and second sides, each with two opposed wheel engaging members configured and dimensioned to engage a corresponding wheel of the wheelset away from a rail point of contact;
• and
• at least one lifting member interposed between said frame and said lifting yoke, such that upon actuation of said at least one lifting member, said yoke may be raised and lowered to selectively engage the wheels of the wheelset;
• wherein said lifting yoke further comprises:
• a first portion which engages said at least one lifting member;
• and
• a set of extendable transverse members, associated with said first portion, and having outward ends, said wheel engaging members being secured to said outward ends of said extendable transverse members.
