THREE-STAGE MAST ELECTROMOTIVE FORKLIFT TO HAVE THE RELATIVELY WIDE SPACE IN THE MIDDLE AREA OF AN INTERNAL MAST

摘要

PURPOSE: A three-stage mast electromotive forklift is provided to secure front field of vision of operators by installing a couple of internal hydraulic cylinders, thereby relatively having a wide space in the middle area of internal mast. CONSTITUTION: A capacity of two internal hydraulic cylinders(60) is set by halving an output corresponding to a limit load of a fork. The internal hydraulic cylinders are respectively located to close to the both insides of an internal mast(40). The lower parts of the internal hydraulic cylinder is combined with a lower connection bar(44) of the internal mast to be fixed in the lower area of the internal mast. The upper parts of the internal hydraulic cylinders are combined with a middle connection bar(42) of the internal mast to be fixed in the middle area of the internal mast. Thereby, the middle area of the internal mast has the relatively wide space to widely secure front field of vision of the operator.
