[0001] The utility model relates to the technical field of material hoists, in particular to a material hoist that is safely used in subway construction. Background Art

[0002] During the construction of the subway, it is inevitable to climb up and down to assemble the structure. If there is a missing material, the lifting hopper will lift it to a higher place for use. There is a great safety hazard simply by pulling the rope. Therefore, material hoists are often used to transport tools and materials. However, ordinary hoists are fixed in position and difficult to move according to construction needs. Their height is also limited, and their scope of use is too restricted, making it difficult to quickly provide workers with the materials they need.

[0003] Now, a new type of material hoist for safe use in subway construction is proposed to solve the above problems. Utility Model Content
