Abstract
PURPOSE: To reduce a weight and a size of a rope reeling out and hoisting tool tilting device of an object lifting machine by providing a cylinder for inclination on the outside of a cylinder for reeling out to realize a double cylinder structure, making an inside diameter of a cylinder tube of the cylinder for reeling out larger than an outside diameter of a piston, and providing a piston storage chamber. CONSTITUTION: When a hoisting tool hoists up an overload and a pressure in a hydraulic chamber 34 exceeds a set pressure of a relief valve 35, hydraulic fluid in the hydraulic chamber 34 flows out, and a piston 28 for reeling out or the like moves initially. Next, it can move with less resistance, a piston rod 29 moves instantaneously because it is pulled by a hoist rope R, and the rope R is reeled out by an amount of winding due to a difference in time. Moreover, a piston rod 30 for guide is moved by a jack or the like to return the piston 28 to A position, and then hydraulic fluid is supplied into the hydraulic chamber 34 to return the piston 28 or the like after the operation. A cylinder 26 for reeling out is moved and four hoist ropes R are pulled in and out to tilt the hoisting tool, That is, a rope reeling out device can be integrated with a hoisting tool tilting device.
