Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, and in particular to an ultra-deep shaft lifting device. Background Art

[0002] In ultra-deep vertical shaft construction, as an auxiliary tunnel, rapid removal of slag is crucial. The appropriate selection of hoisting equipment significantly impacts the progress of the main tunnel excavation. Furthermore, the selection of hoisting equipment requires comprehensive considerations, including the rate of slag lifting, the lowering of large machinery and equipment into the shaft, and the lowering of construction materials. The hoisting system is crucial for lifting and transporting slag, ore, personnel, materials, and equipment. Its lifting capacity directly determines the efficiency of vertical shaft excavation.

[0003] During the construction of ultra-deep shafts, a single-rope hoisting system is often used. This traditional method significantly reduces the efficiency of transport operations during the hoisting process for ultra-deep shafts, such as those exceeding 200 meters. Furthermore, working in ultra-deep shafts places significant pressure on the wire rope, making operations on the platform extremely unstable and unsafe. Utility Model Content
