ABSTRACT:
A hydraulic wheel lift device is adapted to be used with tow vehicles. The device is attached to a tow truck by means of a main boom pivotally secured to a wheel boom, which abuts against the tread portions of tires that the device will lift. A pair of L-shaped arms pivotally secured to the wheel boom are actuated to swing so that they frame the underside of the tires. As a result, each tire is framed by a U-shaped bracket consisting of the wheel boom and the L-shaped arms. The main boom is lifted and in turn lifts the tires and the vehicle being towed.
