Abstract
An embodiment of an object lifting device includes compression straps to which gathering loops and handles are secured. In use, the straps and gathering loops encircle an object to be lifted. A pulling force applied to the handles causes the gathering loops to draw the ends of the straps toward each other, which results in the straps bearing upon the object to be lifted. While the object is held suspended, the weight of the object helps maintain the pulling pressure on the gathering loops and the consequent girthing action by the straps. The object is thus firmly secured by the device allowing it to be safely and easily lifted and transported.
