Assembly and method for lowering and raising a transport trailer bed for loading and unloading a trailer

A transport trailer and mechanical assembly for raising and lowering the bed of the trailer to ground level to facilitate loading and unloading, the transport trailer assembly and mechanical assembly comprising:

• a transport trailer having a trailer bed, having a rear loading end, and a front hitching end, and longitudinal side walls, said front hitching end having a V-shaped yoke member removably securable to a trailer hitch of a vehicle, said transport trailer further having at least one transverse axle, said transverse axle having a wheel attached to opposing ends thereof;
• a mechanical assembly for raising and lowering said transport trailer, said raising and lowering mechanism comprising said V-shaped yoke member pivotally secured to said front end of said trailer by means of a transport pinion, said transport pinion having further mounted thereon a one quarter bevel gear and locking pin;
• said at least one transverse axle having mounted at opposing ends thereof, a one quarter bevel gear with locking pin and a rigid swing arm having a first end secured to said transverse axle, said rigid swing arm having a wheel attached to a second end thereof;
• a gearing shaft mounted to said side wall of said transport trailer by means of a plurality of journaled brackets, said gearing shaft having a left hand worm drive gear in communication with said quarter bevel gear on said front of said transport trailer and a right hand worm drive gear in communication with said quarter bevel gear mounted to said transverse axle;
• said gearing shaft in communication with a power source so as to rotate said gearing shaft and said respective left hand and right hand worm drive gears to cause rotation to said quarter bevel gears so as to cause said swing arms and said wheels mounted thereon to move upwardly and simultaneously causing said transport pinion to move downwardly, to lower said bed of said trailer to said ground level and facilitate loading and unloading of said transport trailer;
• said gearing shaft rotating in an opposite direction so as to cause said respective quarter bevel gears to rotate causing said swing arm and said wheel member to rotate downwardly while simultaneously causing said transport pinion and said front end of said trailer to move upwardly raising said trailer bed to the desired height for transport.
