A log hauling hand truck that acts as a log transporter and lifter has a generally planar height adjustable platform in combination with a retained and adjustable hook. A hand brake has a releasing actuator and an alternative locking actuator for selective braking by an operator. When the load platform is parallel to the ground, the log hauling hand truck is stabilized by locked wheels, a fixed stand, and handle guards, each which independently contact the ground. Roll-off preventing guards may be provided adjacent to the load surface of the adjustable height platform. The platform is preferably open and comprises an expanded metal load surface.
