Introduction： HC trolley integrated electric wire rope hoist has beautiful appearance, compact structure, high transmission efficiency, low overall noise and large lifting area; The trolley shaft adopts eccentric shaft structure, which makes the whole machine more stable; Each bearing position and overall structure are simple, and inspection and maintenance are convenient. At the same time, the electrical part and the trolley transmission part are integrated and can be used after connecting the power supply. The height of the trolley is 400mm lower than that of the conventional double-beam trolley, which can effectively reduce the upper headroom of the double-beam crane and greatly improve the space utilization rate.
