Abstract
A machine for stacking articles such as wooden pallets comprises a frame for supporting a carriage assembly that can be raised and lowered under control of a motor and where the carriage assembly supports an article grasping machine that is slidably mounted on the carriage assembly allowing horizontal movement of the article grasping assembly relative to the carriage. When using the machine to stack wooden pallets, a pallet may be picked up at a first location and elevated and translated so as to overlay a top pallet on a stack of pallets before the one being carried is released.
