Abstract
A carriage assembly has a frame and a carrier movably connected to the frame. First and a second forks are slidably mounted on the frame and movable in transverse directions along the frame. First and a second jacks are connected to and between the first and second forks, respectively, and the carrier. A third jack is connected to and between the carrier and the frame. The carrier and jacks are disposed between a surface of the carriage frame and a rear surface of the forks. The first and second jacks are selectively actuatable to independently move the forks and adjust the spacing between the forks, and the third jack is selectively actuatable to move the carrier and side shift the forks in unison. The carriage assembly is particularly suited for use on a lift mast.
