FIELD: transport.SUBSTANCE: invention relates to handling hardware, particularly, to devices for handling of piece cargoes with indefinite centre of gravity. Crossbar comprises load-bearing beam to support the carriage provided with rollers and hook suspension, carriage drive and cargo grippers. Lower rollers are actuated by gears reduction gearbox shaft and motor controlled by pickup data processing device for automatic control over carriage position. Electromagnet rigidly locks the carriage to said beam while in carriage motion it goes slightly up driven by lever and torsion spring.EFFECT: accelerated handling and mounting operations with cargoes that feature indefinite centre of gravity.4 dwg |
