In the process of concrete production, in order to achieve continuous transportation of materials and avoid the cumbersome and inefficient manual handling, a lifting and conveying device is used to lift and convey concrete. A lifting and conveying device is a mechanical device used to lift materials from one location to another. In concrete production, lifting and conveying devices are usually used to lift and convey raw materials, additives, cement, etc. from one place to a mixing device, or to transport mixed concrete from one place to another.
