Abstract
A lifting device for lifting and moving objects with minimal effort and a method for using the same is provided. The lifting device has a cable attachable to an object and a handle on the cable. Sensors in the handle may sense vertical pressure exerted on the handle and may put out a current to a variable-speed motor in a housing of the lifting device. The motor may release or may retrieve the cable at a speed dependent upon the amount of pressure applied, thereby raising or lowering the object. Pressure of three to five pounds is sufficient to lift any object. The operator may move the object in any direction up to a radius determined by the length of the cable from the object to the housing. The housing may have an upper portion that may slide forward relative to a lower portion. Consequently, this lengthens the radius of movement allowed to the operator.
