Description

technical field [0001] The present application relates to the field of cranes, in particular to a crane with a hoisting trolley, a suspension trolley and a sector gear transmission. Background technique [0002] Existing bridge cranes are used in enterprise workshops. Some workshops are equipped with many machine tools for processing and production. Products and raw materials need to be transported to the next workshop or other departments in real time; the hooks of the cranes in the workshop are hung from the trolley. For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pulle...

For hoisting goods, the trolley can only run back and forth along the double girders of the crane, and the crane can only run back and forth along the cart rails on the cross columns on both sides of the workshop, so that the range of goods that the crane hook can lift is within the distance between the two cart rails in the workshop. Within the plane surrounded by the two ends, when the goods at the edge of the plane need to be hoisted, the hook will be pulled obliquely, and the items farther away from this plane (such as o
