Abstract:
A system and method for lifting heavy bags is presented. A heavy bag lifting apparatus includes a handle, a first grabber device, a second grabber device and a plurality of cross-member devices. Each of the first and second grabber devices has a plurality of pin structures. The first grabber device is pivotally connected to the second grabber device. The cross-member devices pivotally connect the first grabber device and second grabber device together. The plurality of cross-member devices are also pivotally connected to the handle. The first grabber device, the second grabber device and plurality of cross-member device are arranged so that pin structures on the first grabber device and the pin structures on the second grabber device are pushed together in proportion to an amount of weight being lifted by the heavy bag lifter apparatus.
