徴とするクレーンの位置決め制御装置。 In a crane that moves by driving wheels provided at both ends of the girder,
Deceleration position detection pieces are placed at a predetermined interval on the travel reference position side of the crane's target stop position, and deceleration position sensors are placed on the girder to detect this. A plurality of position control sensors are arranged at predetermined intervals in the longitudinal direction of the girder so that each of the position control sensors can separately detect the position near the target stop position and while the girder is running. A girder in which a plurality of position control detection pieces are arranged at predetermined intervals in the longitudinal direction of the girder, and it is determined whether the inclination angle of the girder is at one of a plurality of inclination stages based on the detection signal of the position control sensor. A lateral position measuring device that measures the distance from a lateral reference position of the center of a hoisting machine, which includes a tilt stage determining means disposed on a girder and is movable in a lateral direction perpendicular to the traveling direction of the girder. is installed on the girder, and when the girder travels from the travel reference position and the deceleration position sensor detects the deceleration position detection piece, the traveling speed of the girder is reduced, and then the position control sensor detects the deceleration position detection piece. Based on the signal, the girder inclination stage determination means determines which inclination stage the girder is at, and based on this determination result and the output from the lateral position measuring device, the girder has reached the target stop position. A crane positioning control device characterized in that a girder is provided with a girder position control means that applies a brake to the girder to stop the girder at the time of determination.
