LIFTING APPARATUS

TECHNICAL FIELD OF THE INVENTION The invention disclosed herein generally relates to a lifting apparatus. More particularly, the present invention relates to a lifting apparatus for easily and safely lifting objects, for example, damaged stones or tiles having both regular and irregular shapes from an interlocking pavement.

BACKGROUND One of the most common injuries sustained by construction workers, maintenance crews and those engaged in similar work involves the back due to stresses placed on it by lifting and carrying heavy and awkward objects. Injuries to the hands and feet are also relatively common as workers are frequently required to lift and move heavy objects, for example, stones or tiles and consequently are difficult to grasp.

For example, pavements are made of stones, which are solidly anchored to the adjacent stones. In particular, it is difficult to lift or pull out individual, e.g., damaged or sunken stones from existing interlocking pavements, which may consist of composite stone, tiles, clinker brick, natural stones, and slabs of various shapes, and to replace said stones with corresponding new ones. Currently, workers using different tools and devices, for example, hammer and chisel, and the like for pulling out the damaged stones from existing interlocking pavements. However, the process is relatively cumbersome, — difficult, and time-consuming.

One such a prior art device is described in EP0551828 to Maryan et al, discloses a device for lifting individual laid paving stones out of their interlocking arrangement, two thin lamellas in each case being guided movably up and down in a rigid C-shaped guide and being provided at least in the region of the lower end with resilient

, DK 180497 B1 abutment knobs which in the normal state project at least at one end beyond one plane of the lamella, each lamella being connected to a tappet with the aid of which the lamella is movable up and down. However, the operation of the device is difficult and the worker may feel difficult to operate for lifting the stones.

Another prior art, US 2005/0224773 of O'Neill, discloses a lift mechanism for use in raising ground trench covers includes an axially extending housing, a cam located at one end of the housing, and a latch located at the other end of the housing. Rotational cam movement drives movement of the latch between retracted and actuated positions.

The cam is connected to a latch driving mechanism, which may include springs and/or cables of unequal strength and/or unequal length. However, above-mentioned prior art fails to disclose an alternative design to obtain a lifting apparatus to support lifting beneath the surface for lifting an object, configured with an elongated member is separated by at least one wedge section at the bottom portion, and the intermediate member is bisected at its middle portion into two members with each barb at a distal end, wherein the intermediate member is configured to dispose within the recess of the elongated member by applying force, whereby the force applied on the intermediate member causes the barbs to expand outwards via the pair of slots for securing the object, and the locking rod enabling a user to lift at least one object by using a chain sling, In the light of above-mentioned problems, there is a need for a lifting apparatus for easily and safely lifting objects, for example, stones or tiles having both regular and irregular shapes. Further, there is also need for a lifting apparatus that permits the workman to handle them more conveniently and rapidly and to lift at least one object, for example, stone or tile at once with greater safety and with the expenditure of less effort to himself than would be were lifted by hand.
