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.

Abstract: A log carriage system including a pair of carriages (10, 12) mounted for linear movement along a conveyor track. A pair of linear hydraulic motors (32, 44) each include a piston rod (30, 42) for both clamping and linear transfer of a log. A reversible hydraulic pump (62) transfers oil between working chambers (40, 52) of motors (32, 44) to move the log along a linear path past a cutting station. A three-way, two-position valve (120) connects line (68) to tank (T), and disconnects line (70) from system pump (SP), when pump (62) is operated to move oil from motor (32) to motor (44). Alternatively, linear hydraulic motors (32, 44) can be replaced by rotary hydraulic motors and a cable drive system for both clamping the log and moving the log along the linear path.
