Roof-mounted pulley mechanism

A vehicle-mounted lifting device, comprising:

• a round base frame utilizing a plurality of connecting arms to attach to a rotating bearing;
• a main boom attached to the rotating bearing at a right angle;
• a first brace and a second brace providing structural stability of a main mast in relation to the main boom;
• an auxiliary boom fitting within the main boom, the auxiliary boom moves along a deployment path provided by a pivot point;
• a first pulley provided on the main boom and the auxiliary boom;
• a second pulley equipped with a lifting hook attached to the first pulley by a cable;
• a crank apparatus moving the cable to lift the second pulley and the lifting hook along a lifting travel path, the crank apparatus includes a mounting plate;
• a strap attaching the vehicle-mounted lifting device to a structural element for stability;
• and
• an engagement lever pivoting upon a bearing pin allowing for one-way locking of a geared wheel and thus a reel and,
• wherein the rotating bearing allows one or more parcels to be loaded into one or more openings of a vehicle;
• wherein the one or more parcels are loaded into a trunk of the vehicle;
• wherein the round base frame is securely fastened to a roof area of the vehicle by a series of fasteners;
• wherein a plurality of fasteners are selected from the group consisting of a plurality of additional ratcheting straps, a plurality of clamps, a plurality of bolts, and a plurality of cargo rack attachments;
• wherein excess cable from the cable is wound upon the reel provided with a hand crank and a ratcheting locking mechanism;
• wherein the ratcheting locking mechanism includes the geared wheel mounted on a shaft wherein the reel, housing the cable, is mounted along the shaft which terminates at a nut and is held captive with the nut;
• wherein the rotating bearing allows for a 360-degree travel path of the main mast and the main boom;
• wherein the second pulley and the lifting hook are positioned at the first pulley of the auxiliary boom;
• wherein the vehicle-mounted lifting device provides for lifting the one or more parcels into and out of a vehicle;
• wherein the vehicle is a motor vehicle selected from the group consisting of a sedan, an SUV, a pick-up truck, a box truck, and a van;
• wherein the vehicle-mounted lifting device is installed for each lifting process while the vehicle is in process;
• wherein the second pulley and the first pulley allow both to lift the one or more parcels as generated by the crank apparatus;
• wherein the vehicle-mounted lifting device is left in place while the vehicle is in process;
• wherein a spreader bar used with a sling is used to facilitate the lifting of the one or more parcels;
• and,
• wherein the vehicle-mounted lifting device is made of steel.
