ABSTRACT:
A novel log-hauling carriage which features a band brake assembly for controlling rotation of a drum in the carriage. The carriage includes a rotatably mounted drum containing three sections on which are wound the main and slackpulling lines, and a drop line which is utilized in raising and dropping the logs. The band brake assembly includes a unique crank and lever system for actuating the brake band, whereby the brake band tightly grips the brake drum surface of the brake assembly, thus to prevent drum rotation, with the slackpulling line loose. The brake assembly is controllably released with tensing of the slackpulling line, differing degrees of tensing producing differing degrees of release of the brake assembly.
