Abstract: Two independently operable log delivery systems including a first carriage (A) and a second carriage (B), each carriage the mirror image of the other, each carriage including an upper pair of rollers (80,82) and a lower pair of rollers (84,86), the rollers oriented at ninety degree angles to each other. A main carriage support beam (60) carries each conveyor on pairs of upper rails (70,72) and lower rails (74,76). Upper rollers (80,82) are biased against upper rails (70,72) by means of a torque shaft (108). A dog (32) is mounted at an angle on a dog shaft so that the dogs of each carriage do not intercept one another should the carriages move past each other.
