[0001] The utility model relates to the technical field of hoisting equipment, in particular to a hoisting device for gob-side tunnel retaining operations. Background Art

[0002] When working on a tunnel-retaining working face along the goaf, it is necessary to temporarily lift heavier equipment, materials, parts, etc., but it is often difficult to find a suitable lifting point, or to use an anchor cable lock to lift it through a drilling rig, which is inconvenient to use. At the same time, when temporarily lifting a water pump, there is a great safety hazard if the lifting point is hung on the gangway, and using a drilling rig to install an anchor cable to lift the water pump is time-consuming, labor-intensive, and has low lifting efficiency. Therefore, a lifting device for working on a tunnel-retaining working face along the goaf is proposed to address the above problems. Utility Model Content
