A hoist and dolly apparatus is disclosed which is adapted to straddle, raise, and transport an object relative to a horizontal surface. The apparatus is characterized by the provision of a horizontal center bar member, and a pair of generally U-shaped leg means pivotally connected with each end of the center bar member, respectively, for pivotal movement about vertical pivot axes toward positions affording increased stability to the apparatus during lifting and transport of the object. Lifting means including boom and cable winch means are connected with the central portion of the horizontal center bar member for raising the object and suspending it at an elevated position for transport relative to the horizontal surface. Locking means are provided for locking the wheels, the leg means, and the lifting means in selected positions relative to the center bar member for maximum stability and ease of transport.
