1. A tiltable hand truck comprising:a substantially U-shaped frame, having two side members fixedly joined with a rear member forming a rigid structure, wherein the space between said side members furthest from said rear member defines an open front; a stop shaft fixedly attached to said two side members near said rear member; at least one pair of wheels, each wheel axially attached to each of said two side members; a tiltable platform pivotally attached at an intermediate point between said two side members, wherein said tiltable platform is capable of swinging downward to the ground at said open front, and wherein said stop shaft keeps said tiltable platform leveled and does not allow said tiltable platform to swing downward to the ground in the opposite direction; a connecting member fixedly attached to said rear member; a steering assembly comprising at least one wheel axially attached to a steering shaft, said steering shaft being fixedly attached to said connecting member. 2. The tiltable hand truck of claim 1, further comprising a handle connected to said steering assembly.3. The tiltable hand truck of claim 1, further comprising a handle connected to said substantially U-shaped frame.4. The tiltable hand truck of claim 2, wherein said handle further comprises a multidirectional movable joint.5. The tiltable hand truck of claim 1, wherein said at least one pair of wheels are each axially attached to each of said side members near said open front.6. The tiltable hand truck of claim 1, wherein two wheels are axially attached to said steering shaft.7. The tiltable hand truck of claim 1, wherein said two side members are substantially parallel.8. The tiltable hand truck of claim 1, wherein said connecting member is fixedly attached to said right side member.9. The tiltable hand truck of claim 1, wherein said connecting member is fixedly attached to said left side member.10. The tiltable hand truck of claim 1, wherein said steering shaft is releasably and rotatably connected to said connecting member.11. The tiltable hand truck of claim 1, wherein said connecting member is releasably and rotatably connected to said rear member.12. The tiltable hand truck of claim 1, wherein said connecting member is releasably and rotatably connected to both said rear member and said steering assembly.13. The tiltable band truck of claim 1, wherein said steering assembly and said shaft are connected by means of a pin and a socket.14. The tiltable band truck of claim 1, wherein said connecting member and said rear member are connected by means of a pin and a socket.15. The tiltable hand truck of claim 1, where in said connecting member is connected to both said rear member and said steering assembly by means of a pin and a socket.16. The tiltable hand truck of claim 1, wherein said each wheel of said pair of wheels is axially attached outwardly to each of said two side members near said open front.17. The tiltable hand truck of claim 1, further comprising a latch attached to said rear member, wherein said tiltable platform is releasably latched to said rear member.18. The tiltable hand truck of claim 1, further comprising a latch attached to said connecting member, wherein said tiltable platform is releasably latched to said connecting member.19. A transport device comprising:a means for carrying a load, tiltable attached to a means for support; a means for halting the tilt of said carrying means attached to said support means; a means for moving said support means attached to said support means; a means for latching said carrying means attached to said support means; whereby said transport device can be moved in close proximity to said load, said carrying means tilted to the base of said load, said load tilted such that the carrying means can access the bottom side of said load, said carrying means tilted back into position, whereby said halting means impedes further motion and stabilizes said carrying means, said means for latching applied to said carrying means to impede further tilting, said transport device with said load can be moved to a new location, said carrying means tilted to the ground and said load offloaded into a desired position.
