By way of example and without implying any limitation to the scope of this invention, the loading device may be employed for loading of packed refrigerators. BACKGROUND OF INVENTION The loading of packed refrigerators has hitherto been manually effected onto vehicles for transportation of packed refrigerators from the manufacturing location to a distal location. As such refrigerators were loaded manually onto a vehicle and whereby the efficiency of such an operation was reduced considerable. Further, a manual loading of such refrigerators often resulted in a damage to the refrigerators. Yet another disadvantage by the known manual operation of loading was that by tilting of the packed refrigerator, and whereby oil and refrigerant enters the system. Instead of a manual operation, a fork lift could be employed, but which is not a continuous operation. OBJECTS OF THE INVENTION An object of this invention is to propose a device for loading and unloading of products such as a refrigerator, from a lower to an elevated location and vice versa. Another object of this invention is to propose a device for loading and unloading of products such as refrigerator, from a lower to an elevated location and vice versa and which can be effected as a continuous operation. Still another object of this invention is to purpose a device for loading and unloading of products such a a refrigerator, from a lower to an elevated location and vice versa which is efficient. Yet another object of this invention is to propose a device for loading and unloading of products such as a refrigerator, from a lower to an elevated location and vice versa without causing any damage to the refrigerator. A further objet of this invention is to propose a device for loading and unloading of products such as a refrigerator, from a lower to an elevated location and vice versa which can be transported to any location. STATEMENT OF THE INVENTION According to this invention there is provided A device for the loading and unloading of products from a lower to an elevated location and vice-versa particularly loading/ unloading of refrigerator on to a vehicle wherein the device comprises of:- (i) a first platform (P1) and a second platform (P2) connected to a sprocket chain (SC) driven by sprocket (SP) in such a way that when platform (P1) is in elevated position, the platform P2is in a lowered position and vice-versa; (ii) a motive means (M) comprising a motor coupled to a reduction gear (RG) which is adapted to drive sprocket (SP) through a clutch (CL); (iii) a delivery means comprising a plurality of rotatable housings or tubular members ( TM ) each disposed on its fixed shaft (FS) with bearings (B1) being provided at either end; (iv) a frame (F) having two pillars (F1) and (F2) to rotatably support set of rollers (NR); (v) a control member (CM) adapted to control the functions of drive means; (vi) a trolley (TR), to support the device.

Referring to the drawings, the apparatus comprises a first platform P1 and a second platform P2 and such that when platform PI is in an elevated position platform P2 is in a lowered position and vice versa. Thus, in a lowered position of either of platforms P1 or P2, the article or the refrigerator is loaded onto said platform. When the platform P1 or P2 is in a raised or elevated position, the refrigerator is discharged onto a vehicle through the delivery means as particularly illustrated in Fig. 3.
