  • Patent number: 4534579
    Abstract: A mechanical wheel lift for engaging and lifting the wheels of a car for use on a tow truck having a winch and a cable thereon. The wheel lift comprises a support coupled vertically to the rear of the truck, a pair of vertical tracks coupled to the support, a trolley vertically movable along the tracks, a pair of cam follower rollers coupled to the support, a pivot member pivotally coupled to the trolley and having a planar cam surface thereon slidably engaging and inclined to the cam follower rollers, and a pair of wheel-engaging forks coupled to the pivot member. The winch and cable vertically reciprocate the trolley to thereby vertically reciprocate the forks. During this movement, the pivot member pivots the forks towards or away from the truck. The wheel lift is stowable, can be used without removal of tow slings and avoids the use of hydraulics.
