Abstract
PURPOSE: To provide a hydraulic cylinder wherein the stroke can be suitably varied so that it can be still used without being exchanged even if an attachment is exchanged for another and the stroke thereof can be increased for transportation thereof to optimize the folding of a working equipment containing the cylinder.
CONSTITUTION: A piston 2 having a piston rod 1 integrally connectd thereto is fitted in a cylinder body 8 having a cylinder head 8' in which a grease cylinder chamber 6 is formed for receiving therein a foot section 3' of a limiting piston 3. An end wall 9 of the cylinder body 8 adjacent to the piston rod 1 also has a grease cylinder chamber 5 in which another limiting piston 4 is fitted in a similar manner. In case such hydraulic cylinder is applied to a power shovel P, a stroke of the cylinder appropriate for an associated attachment can be easily obtained by feeding grease into or discharging grease from the grease cylinder chamber 6 to move the limiting piston 3 or 4 forwardly or rearwardly.
