Реферат: Load Lifting Carriage and Mast Assembly Abstract A carriage and mast assembly including a mast having outer sides and a first pair of movable inner uprights and a second pair of fixed outer uprights, a load lifting carriage, a pair of free lift cylinders being directly connected to the first pair of uprights and to the load lifting carriage, a pair of mast lift cylinders being connected to the first pair of uprights and to the second of uprights, each pair of cylinders being disposed at the outer sides, and a pair of means for communicating fluid between one of the free lift cylinders and one of the mast lift cylinders, respectively. The problems of using lift chains and sheaves to free lift the carriage and operator visibility through the mast are avoided by directly connecting the free lift cylinders to the carriage and mast and disposing these cylinders outside the mast.
