Abstract: A wheel locking device comprising a number of interlocking components that are adapted to receive a wheel (or a wheeled apparatus), and said components can be adjusted to accommodate a variety of wheels of different diameters. The wheel locking device further comprises a rotatable and adjustable bar that is utilized to secure the wheel in place. In further embodiments, the device comprises a lock receiving bore which is adapted to receive a lock.

Abstract: A lifting device having an axle and a pair of wheels attached to the axle, a support element secured to the axle, a vertical element secured to the axle at an angle relative to the support element, and a handle secured to the distal end of the vertical element. In some embodiments, a safety arm is rotatably connected to the support element and the safety arm is moved from a closed position to an extended position, and vice versa, by simply rotating a handle grip which actuates a lever thereby moving a release pin from an engaged position to a dis-engaged position. The release pin secures the safety arm in the closed and extended positions. In further embodiments, a tooth is rotatably connected to the distal end of the support element and the tooth is biased inwards towards the lifting device by at least one spring.
