Title:
HYDRAULICALLY OPERATED WORKING MACHINE
Document Type and Number:
Japanese Patent JP3008277
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a revolutionary hydraulically operated working machine excellent in operatability by changing a fixed idea that a main body part is integrated longitudinally long and substantially/significantly reducing a height of the main body part without impairing the function of the machine based on a revolutionary idea separating a piston moving working part and a pressure oil feed part, for example, in the case angle bars are arranged at short intervals to a wall face, the working is made possible.
SOLUTION: The hydraulically operated working machine is constructed so that above a piston moving working part A, in which a piston 2 is moved as pressurized by a pressure oil fed to a cylinder, a working part 4 for piercing, cutting, bending a material to be worked by moving the piston 2 is arranged, an oil pressure feed part B arranged with a pressurizing feed mechanism having an electric motor 5 to feed a pressure oil to the piston is arranged. The oil pressure feed part B is protruded at the state roughly at right angle or inclined at an prescribed angle to sideward for the piston moving working part A at lower side.
