发明名称 Mast construction for a lift truck
摘要 A mast includes a base section, an outer telescopic section and an inner telescopic section which are raised and lowered by a pair of main lift cylinders. A fork carriage is slidably mounted to the inner telescopic section and is raised and lowered thereon by a pair of free lift cylinders. The mast elements are arranged to form two mast columns which produce minimum obstruction to the truck operator's field of view when looking forward through the mast.
