の安全装置。[Scope of claim for utility model registration] A boom is provided on the vehicle so that it can be rotated and raised freely,
A swing drive means for driving the boom to swing and a hoisting drive means for driving the boom to raise and lower, and a swing operation means and a hoisting operation means for respectively controlling the swing drive means and the hoisting drive means to drive the boom to raise and lower and swing. A safety device for a work machine having a boom, which is equipped with a safety device that prevents the boom from interfering with obstacles existing in the area where the boom is located, and in particular, a swing angle that detects the swing angle of the boom. a detection means, a heave angle detection means for detecting a heave angle of the boom, and a means for regulating the lodging motion of the boom, which is set in front of a dangerous lodging area where there is a risk of the boom coming into contact with the obstacle when the boom is driven to lie down. lodging restriction determining means for determining whether the boom has reached an area where the boom starts to move when the boom reaches the obstacle when the boom is rotated to the right; The turning angle detecting means and the luffing angle detecting means determine whether the boom has reached an area set in front of the dangerous right turning area where there is a risk of the boom coming into contact with the boom and starting to restrict the right turning movement of the boom. and a right-turn restriction determining means that determines the right-hand rotation restriction by receiving a signal from the left-hand turn control means, which is set in front of a dangerous left-hand turn area in which there is a risk of the boom coming into contact with the obstacle when the boom is driven to turn left. a left-turn restriction determining means that determines whether the boom has reached a region where restriction is to be started in response to signals from the turning angle detection means and the heave angle detection means; and a lodging operation that detects a lodging operation of the hoisting operation means. a detection means, a right turning operation detection means for detecting a right turning operation of the turning operation means, a left turning operation detecting means for detecting a left turning operation of the turning operation means, and a lodging drive regulation for regulating the lodging drive of the boom. a right-turning drive regulating means for regulating the right-handed turning drive of the boom; a left-handed turning drive regulating means for regulating the left-turning drive of the boom; and both the lodging operation detection means and the lodging regulation determining means are activated. a lodging drive stop signal generating means that outputs a signal to the lodging drive regulating means when the lodging drive regulating means is actuated; a right-turn drive stop signal generation means for outputting a signal to the left-turn drive stop signal, and a left-turn drive stop signal for outputting a signal to the left-turn drive restriction means when both the left-turn operation detection means and the left-turn restriction determination means are activated. A safety device for a work machine having a boom, characterized in that it is equipped with a signal generating means.
