The hand truck includes a frame having a first section for being gripped by a user to manipulate and push the hand truck. The second section defines a carriage extending outwardly from the first section. The carriage serves as a loading platform for holding and supporting material such as a log loaded thereon. A pair of wheels are provided to enable ready movement of the hand truck over a supported surface such as the ground. To facilitate loading and storing a log during transportation, a loading strap is provided upon which a log can be rolled. The outermost end portion of the strap can then be gripped and moved towards the hand truck to enable movement of the log along the strap as it is advanced towards the carriage for storage and transportation. | 07-24-2014 |
