Roof-Mounted Pulley Mechanism

Story Behind the Invention

Inventor Mark Koring of Greensburg, PA has created a device to lift heavy objects in and out of various types of vehicles without the use of portable hydraulic lifts, tow trucks, or cranes.

There are many times when a heavy object must be lifted in and out of a vehicle. However, enlisting the help of friends, neighbors, or family is not always possible.

Loading a 90-pound lawnmower into his car trunk by himself was hard on Marks back. He would always struggle getting it into his vehicle without damaging his car or the lawnmower itself. Eventually, he just knew there had to be a better way. The Roof-Mounted Pulley Mechanism is his solution.

But how does it work? The invention would be made in three different sizes, with the smallest version for the trunk area of a car or SUV, a medium-sized version for a pickup truck, and a large version for delivery trucks. In all cases, the design is the same with a rotating base that supports a center shaft and a horizontal extension arm. One end of the extension arm has a ratcheting crank with a reel of high strength cable. The cable is wound through a lower pulley with a lifting hook to double the lifting power of the ratcheting crank. The device lifts items in and out of the cargo area by lifting the object, swinging it in or out of the cargo area, and lowering it into position. As the invention is attached to the body/frame of the vehicle, the vehicle acts as a counterweight to ensure stability. This will be perfect for lifting loads when other people or equipment are not available.
