LIFTING APPARATUS

TECHNICAL FIELD OF THE INVENTION The invention disclosed herein generally relates to system comprising a lifting apparatus and a number of objects to be lifted by the lifting apparatus. More particularly, the present invention relates to a lifting apparatus used for raising, transporting, lowering and safely placing an object or stacked objects, for example, boxes.

BACKGROUND Material lifting equipment is probably required in many industries for handling objects, for example, boxes. The boxes are used for storing and transporting materials from one place to another using lifting equipment. Handling a large number of boxes is too heavy for personnel to carry and maneuver around by hand. Currently, many industries use different types of lifting or logistic equipment such as, lifting gears, cranes, and lift trucks. The existing lifting equipment, cranes, and lift trucks have long been used in industries for handling stacked boxes and containers. The cranes and lift trucks are manually operated by one or more operators to raise, transport, and lower the stacked objects, for example, boxes.

However, handling stacked boxes using the existing lifting equipment, cranes, and lift trucks is difficult and cumbersome. If the lift truck is used for handling the stacked boxes, then the jaws or claws of the lift truck could damage the side portions of — the boxes due to tightness. The lift truck frequently cannot gain access to the bottom portion of the stacked boxes, thereby additional equipment and workers are required. The existing lifting equipment and the lift trucks are in need of regular maintenance, which incurs additional cost.

, DK 180335 B1 A prior art, US 7080824 B1 of George David W et al., discloses a chain motor drive controller for a chain hoist. The system employs a position encoder including a position sensor located within the casing of the chain hoist to producing encoded electrical position signals. Another prior art, CN 206985639 U of Wuxi Aiyili Machinery Co Ltd, discloses a pallet fork with two lances for carrying turnover box. However, the prior arts lack to describe a lifting apparatus with entire gripping means and lifting gear enabling it to be self-hoisting, for securely handling box-shaped loads. In the light of above-mentioned problems, there is a need for an efficient lifting apparatus for raising, transporting, and lowering objects. Further, there is also a need for providing an inexpensive and simple lifting apparatus for handling the stacked objects, for example, boxes.
