  • Patent number: 5915500
    Abstract: The lifting apparatus can be used to lift various types of vehicles. In one embodiment, the apparatus has two posts that are spaced apart from each other. Each post has a lifting member that is capable of traversing up and down along the post. Each lifting member has two lifting arms that extend therefrom. Each lifting arm includes an inner end portion and an outer end portion. The lifting arm is pivotally coupled to the lifting member. The inner end portion and outer end portion of each lifting arm are telescopically coupled so that the lifting arm length can be extended or shortened as necessary. One version of the lifting arm has a pad at the outer end thereof, which pad contacts the vehicle chassis. Another version of the lifting arm has a tire fork adapter coupled to the outer end thereof. The tire fork adapter engages the tires of a nonroadworthy vehicle, such as turf equipment. The tire fork is provided with prongs that are located underneath the vehicle tire.
