FIELD: atomic mechanical engineering, nuclear reactor refueling equipment.
SUBSTANCE: proposed refueling device has bridge crane with twin cable pulley. Movable block of pulley is provided with additional mass affording strictly vertical displacement of fuel elements. Pulley cables are passed through guide holes in supports of fixed top blocks. Guide holes are aligned with axes of cables running onto movable twin block. Additional mass provides for desired precision of guiding movable block and gripping fuel elements being handled.
EFFECT: simplified mechanical design.
