FIELD: materials handling facilities; tower cranes.
SUBSTANCE: according to production plan, zones with different types of crane movement limits related to concrete objects are defined. Said zones are introduced into personal computer, not included into instrument complex of coordinate protection, under laboratory conditions. Using special software, array of data is formed in computer, each element of which corresponds to building site member and contains information of prohibited movement of crane in corresponding point. Said array is recorded in reprogrammable read-only memory of coordinate protection system which, basing on signals from transmitters, defining position of crane and its members and by signals from reprogrammable read-only memory forms drive locking signals if crane or its working members get into restricted zone.
EFFECT: provision of crane coordinate protection of high efficiency using simple devices.
