DEVICE FOR INSPECTION OF HORIZONTALITY OF CRANE

摘要

The invention relates to the crane building. A device for inspection of the horizontality of crane contains a housing, in which an airtight cavity with transparent cover with scale is located, and liquid in the cavity with air bubble. Housing is motionlessly fastened to the clamp with lateral laths,one of which is hingedly connected to the clamp. Lateral laths at the ends are equipped with contact jaws. The distance between the ends of laths is proportional to the diameter of support-rotating circle of crane. The increase of accuracy of the measurements of inclination of crane is a technical result.
