ABSTRACT:
Apparatus for loading and unloading objects such as boats to and from elevated surfaces such as the tops of vehicles. Spring biased structures provide for allowing the object to lie substantially horizontally on top of a vehicle and for causing one end of the object to be elevated for unloading purposes when desired. The spring biased structure also prevents the object from pivoting too quickly during the loading process and thereby causing an undesirable impact between the vehicle top and the object during this loading process. A winch is provided for pulling the object onto the vehicle top or for allowing a controlled unloading by utilizing a gravity force limited by the winch. Rollers are clamped on one end of the object and a rod pivotally attached to the vehicle causes the roller end of the object to be spaced sufficiently from the vehicle when the rollers are near the ground to thereby aid in the controlled handling of the object.
