Description

[0002] A material elevator is a device used to transport materials vertically or diagonally, usually in industrial production lines or storage facilities. It can effectively transport materials from one location to another, improve production efficiency and reduce labor costs. Material elevators play an important role in industrial production. They can improve production efficiency, reduce labor intensity, and ensure the smooth operation of the production line.

[0003] "A material hoist for construction engineering with publication number 'CN212246068U'" discloses a transmission connection between a lifting mechanism and a slide bar, and the connecting rod slides in a transmission groove to drive a guardrail to slide up and down between two slide bars to achieve material lifting. During the lifting process, the material can be limited and fixed by a limiting mechanism. It has strong stability and is not prone to shaking, thus preventing the material from being bumped or falling. It is safe and reliable. However, when the above-mentioned material hoist is in use, the limiting plate is driven to move by rotating the fastening screw to clamp and fix the material. However, it is not convenient to clamp and loosen the material during use, and the material can only move in the vertical direction. When unloading materials from a high place, it is usually necessary to move the material in the horizontal direction. There is a certain risk in removing the material during this process. Therefore, in order to solve the above problems, the present application provides a material hoist for construction engineering.
