DEVICE FOR DETERMINATION OF GEOMETRIC PARAMETERS OF RAILS OF CRANE RUNWAYS

摘要

A device for determination of geometric parameters of rails of crane runways comprises laser emitter mounted on the inner cup stage. The stage is arranged with possibility of self-leveling with respect to horizontal plane and one straight line that belongs to that plane, with possibility of control of direction of the line. The inner cup is fixed to the outer cup fixed to the body fixed in the cramp installed on the rail.
