[0001] The invention belongs to the field of mechanical equipment maintenance, and specifically refers to an easy-to-operate hoisting device for mechanical equipment failure maintenance. Background Art

[0002] At present, in the field of mechanical equipment failure maintenance, lifting devices have been widely used in heavy object handling, installation and commissioning, etc. Although traditional lifting devices can meet basic lifting needs, their fixed structure and inconvenient operation have gradually become prominent, especially in complex environments with limited space or high multi-directional lifting requirements. It is difficult to meet the needs of efficient and accurate positioning, resulting in low work efficiency, increased labor costs and time consumption.

[0003] In order to overcome these limitations, a variety of improvement measures have emerged on the market: First, manually adjustable lifting devices, which change the height and horizontal position of the hook by manually adjusting the pulley block or chain. Although this method is simple and easy, it has poor precision control and is not very safe for heavy or valuable items; second, lifting equipment driven by hydraulic control systems can achieve more precise height adjustment, but has limited support for lateral displacement and is costly, making it unsuitable for small businesses and personal workshops; third, electric hoist-type lifting tools can better complete vertical lifting operations, but have weak fine-tuning capabilities in the horizontal direction and lack flexibility.
