    Abstract: An apparatus for traversing loose, granular material includes a frame and a rotatable traction device connected to the frame. The outer surface of the rotatable traction device includes spaced apart curvilinear or angular traction ridges and spaced apart curved or angular valleys, each valley being between a pair of adjacent traction ridges, thereby forming curved or angular shovel-like elements. Each shovel-like element has a leading curved or angular surface and a confining curved or angular surface. Rotation of the rotatable traction device results in rotation of the shovel-like elements through the loose, granular material. Each shovel-like element enfolds a portion of the loose, granular material bordering the leading curved or angular surface of the shovel-like element, and the confining curved or angular surface of the shovel-like element confines at least part of the enfolded portion of the material, thereby confining and restricting displacement of the enfolded portion of the material.

    Abstract: The hand truck is configured for the carriage of large, heavy, generally cylindrical buckets of wallboard compound, paint, etc. The handlebars include one or more latch bars extending therebetween, with each latch bar having a fixed bale latch. The latch bars and bale latches are configured so that when a standard material bucket is placed on the platform when the platform is resting on the surface, the bale of the bucket will clear the bale latch when the bale is swung rearwardly toward the handlebars. However, when the truck is tilted rearwardly for transport, the bucket tilts forwardly and the bale catches on the bale latch, thereby securing the bucket on the truck. When the truck is repositioned with the platform resting on the surface, the handlebars swing toward the upper edge of the bucket to provide sufficient slack to allow the bale to be removed from the bale latch.
