Swinging angle measuring apparatus for anti-swing operation of crane

摘要

The invention discloses a device for measuring the angle of swing deflection for crane operation free of swing deflection. The two-dimensional measuring device is an industrial high-performance device and on the whole comprises a rope 1 as fixed part, two laser sensors 2 and 2', and rectangular laser-reflection plates 3 and 3'. The rectangular laser-reflection plates (made of steel) 3 and 3' are fitted in right-angled relationship on one side of the rope 1. The two laser sensors 2 and 2' are fitted at right angles to one another on the opposite sides of the laser-reflection plates 3 and 3'. The position of the laser-reflection plates lies at the zero-condition point, and the swing-out angle of the rope is determined by the distance between the laser sensors and the reflection plates.
