A dual ergonomic platform truck includes a frame assembly having a pair of first and second segments, a pair of guide rods each having a first end connected to one of the first segments and a second end connected to one of the second segments. A pair of platform assemblies are moveable along the pair of guide rods respectively. Each platform assembly includes a deck guide that receives the guide rod and a platform that is connected to the deck guide and is constructed to hold items. Each platform assembly also includes a first linear bearing that is received within the deck guide and a spring support bracket connected to the deck guide. A pair of springs are used to lift the pair of platform assemblies respectively. Each spring is connected to the first and second segments of the frame assembly. The platform truck may also include a self-aligning platform assembly. A handtruck includes a frame assembly, at pair of wheels, a guide rod, a platform assembly that is moveable along the guide rod, and a spring that provides a lifting force to the platform assembly. The handtruck may also include a latch system for use in preventing the platform assembly from moving along the guide rod and a hydraulic cylinder or frictional dampers for use in damping (slowing) the spring force as it is applied to the platform assembly. |
