Material handling system and method and load carrying vehicle thereof

A method for handling of load, for moving the load using a load carrying vehicle from a first location to a second location, the load carrying vehicle comprising a body having a platform defining an upper surface, a wheel arrangement attached to lower section of the platform, and a tray being releasably attached to the upper surface of the platform, the method comprises the steps:

• a. loading, at the first location, the load onto a first tray while mounted on the platform of the load carrying vehicle;
• b. moving the load carrying vehicle comprising the tray mounted thereon to the second location comprising at least one unloading apparatus for unloading a load contained in a tray of a load carrying vehicle having a platform defining an upper surface adapted to releasably receive the tray, the unloading apparatus comprising
• a rotator having a support surface for parking of the load carrying vehicle comprising a body having
• a platform defining an upper surface and a wheel arrangement attached to lower section of the platform, the tray being releasably attached to the upper surface of the platform, and
• a plurality of frames arranged in a spaced apart relationship with respect to each other along the support surface, the frames being adapted to secure the tray to the rotator and lifting the tray from the platform, and means for rotating the rotator about a longitudinal axis of the tray for unloading of the load;
• and
• c. removing the tray from the platform of the load carrying vehicle and unloading the tray via the rotator.

A tray when being unloaded using an unloading apparatus, the tray being adapted for attachment to a platform of a load carrying vehicle having hook members pivotally attached to sides of the platform, the tray comprising

• the tray having
• side walls having upper ends comprising side beams and end walls having a plurality of pin members on each of the side wall of each tray, the pin members are adapted to receive the hook members for releasably attaching the tray to the platform wherein the walls end, having upper ends comprising end beams, the side and end beams being joined together defining an open upper end for receiving a load for storage in the tray, the open end comprising front and rear corners adapted to receive jaws of a lifting mechanism for lifting the tray from the platform and tilting the tray, wherein
• the side beams extend beyond the corners defining beam extensions to receive the jaws of the lifting mechanism such that the beam extensions are sandwiched between the jaws and particular arc sections of frames of the rotator, wherein
• the unloading apparatus is for unloading a load contained in a tray of a load carrying vehicle having a platform defining an upper surface adapted to releasably receive the tray, the unloading apparatus comprising
• a rotator having a support surface for parking of the load carrying vehicle comprising a body having a platform defining an upper surface and a wheel arrangement attached to lower section of the platform, the tray being releasably attached to the upper surface of the platform,
• a plurality of frames arranged in a spaced apart relationship with respect to each other along the support surface, the frames being adapted to secure the tray to the rotator and lifting the tray from the platform, and
• means for rotating the rotator about a longitudinal axis of the tray for unloading of the load.
