The invention relates to a handling equipment, which is used in construction and industry, and occupies an important place among the facilities intended for servicing of complex industrial and building complexes, quarries and large warehouses, as the main handling facility. A cable crane consists of two supports, between which a bearing rope is pulled for displacement of a crane trolley with a gripping body, motors and gears mounted on the supports. Each support has an actuating screw, which has a possibility of bringing into rotary motion by a motor and a reducer of a guide, and a slide, which is mounted with possibility of movement in the guide and interacting with a screw, wherein to the slides of supports by means of couplings ends of a bearing rope are secured to move the crane trolley under its own weight by placing the slides in the supports at various heights. The technical result: reduction in energy and resource consumption, as well as reduction of the cost of the crane by eliminating the mechanism of the trolley movement (traction rope is not used), elimination of supports and load lifting mechanism. Movement of goods is carried out by the force of gravity. |
