Abstract:
A hand truck that weighs less than twenty-three kilograms (23 kg) when unloaded. The hand truck has a platform with wheels, which permits the platform to travel along a beam while reducing the chances of seizing as objects are loaded on or unloaded from the hand truck. The hand truck also has a strut pulley sub-assembly that controls the rate of travel of the platform along the beam.

Claim (Index 1):
A hand truck comprising:\n (a) an H-beam having a length, the beam comprising:\n (a1) an H-beam top; and \n (a2) an H-beam bottom; \n (b) a platform body sub-assembly comprising platform rollers, the platform rollers engaging the H-beam to permit the platform body sub-assembly to travel along a portion of the length of the H-beam; (c) a plate affixed to the platform body sub-assembly to permit the plate to travel concurrently with the platform body sub-assembly, the plate being arranged substantially perpendicular to the H-beam; (d) a strut pulley sub-assembly arranged substantially parallel to the beam, the strut pulley sub-assembly comprising:\n (d1) an upper end; \n (d2) a lower end; \n (d3) a dampener strut comprising:\n (d1A) a strut top; and \n (d1B) a strut bottom; \n \n (d4) a spring arranged substantially parallel to the dampener strut, the spring comprising:\n (d4A) a spring top; and \n (d4B) a spring bottom; \n \n (d5) a strut mount mechanically connecting the strut bottom to the spring bottom; and \n (d6) a pulley mount mechanically connecting the strut top to the spring top; \n (e) a head sub-assembly connecting the upper end of the strut pulley sub-assembly to the beam top; (f) a rope extending from the platform body sub-assembly to the pulley mount through the head sub-assembly, the rope connecting the platform body sub-assembly to the pulley mount; and (g) a total unloaded weight of less than twenty-three kilograms (23 kg).
