荷防止装置。[Claims for Utility Model Registration] 1. An overload prevention device that regulates the operation of a boom in order to prevent overload operation of a working device equipped with a boom, the overload prevention device acting in a direction that causes the working device to overturn. Actual load calculation means for calculating a lateral moment; and Standard rating calculation means for calculating a standard rated overturning moment when the working equipment is installed horizontally based on work conditions such as a tension width of an outrigger supporting the working equipment. and an inclination detection means for detecting an inclination of the working device; correcting the reference rated overturning moment based on the inclination detected by the inclination detection means;
The boom is characterized by comprising: an effective rating calculation means for calculating an effective rated overturning moment; and a controller that outputs an operation regulation signal for the boom when the actual overturning moment reaches the effective rated overturning moment. Overload prevention device for working equipment. 2. An overload prevention device that regulates the operation of the boom in order to prevent overload operation of a working device equipped with a boom, and an actual load calculation that calculates the actual axial force acting on a hoisting cylinder that operates the boom to hoist. means for calculating a standard rated axial force in a state where the working device is installed horizontally based on work conditions such as tension width and working radius of an outrigger supporting the working device; inclination detection means for detecting an inclination; effective rated calculation means for correcting the reference rated axial force and calculating an effective rated axial force based on the inclination detected by the inclination detection means; An overload prevention device for a working device, comprising a controller that outputs an operation regulation signal for the boom when the effective rated axial force is reached.
