Abstract
A railway wheel lifting device is provided wherein a railway wheel can be readily and positively affixed to a lifting device. Upon such affixing and lifting, the wheel can be moved as necessary with the lifting device. Positive locking mechanisms are provided whereby the rim section of the wheel is held between depending legs of a frame support. When it is desired to release the wheel, an operating cylinder is operatively connected to operating rods which in turn can move cam assemblies out of contact with the wheel to thereby permit the wheel to be released from the lifting device.
