Pallet and handtruck

A material transport system, comprising:

• a pallet having front and rear ends, and wherein the rear end of the pallet includes a mechanical coupling;
• a handtruck with a set of ground-contacting wheels and a front end with a lift bar adapted for removeable attachment to the mechanical coupling on the rear end of the pallet;
• wherein the pallet includes a set of front wheels and a conveyor belt disposed on front and rear rollers;
• and
• wherein the lift bar on the handtruck has a lower position wherein the handtruck is used to transport the pallet on a ground surface, and an upper position wherein the rear end of the pallet lifted to unload material from the conveyor belt to a ground surface;
• and
• further including a drive wheel retraction mechanism to prevent movement of the conveyor belt regardless of the position of the lift bar.

A material transport system, comprising:

• a pallet having front and rear ends, a set of front wheels at the front end, a mechanical coupling at the rear end, front and rear rollers, a conveyor belt disposed on the front and rear rollers, and a drive wheel coupled to the front roller;
• and
• a handtruck having a set of ground-contacting wheels, a front end, and a lift bar at the front end, wherein the lift bar is adapted for removeable attachment to the mechanical coupling at the rear end of the pallet;
• wherein the lift bar on the handtruck has a lower position and an upper position, wherein when the lift bar on the handtruck is in the lower position the handtruck is used to transport the pallet in a rolling motion on the front wheels of the pallet on a ground surface, wherein in the lower position the pallet is level and the drive wheel of the pallet does not contact the ground surface, and
• wherein when the lift bar on the handtruck is in the upper position, the rear end of the pallet is lifted to unload material from the conveyor belt to the ground surface, wherein in the upper position the drive wheel of the pallet contacts the ground surface and the conveyor belt disposed on the front and rear rollers moves forward when the drive wheel coupled to the front roller moves rearward, causing the conveyor belt to move and unload the material onto the ground surface when the handtruck and pallet are moved rearwardly.
