[0002] In the field of construction, there is a wide variety and large quantity of building materials, including but not limited to bricks, steel, cement, wood, etc. They are the foundation for constructing various buildings, and their efficient transportation and accurate placement are crucial for the progress and quality of construction projects.

[0003] During the construction process, it is often necessary to lift these materials to different heights and positions to meet the construction requirements. Therefore, the material lifting device has become an indispensable and important equipment in construction.

[0004] However, traditional building material lifting devices have many defects. In practical applications, since the material support plate is generally at the front end of the lifting device and the materials are also concentrated at the front end of the lifting device, it is extremely easy to cause the center of gravity of the device to shift, making the entire lifting process unstable and prone to overweight and tilting. There are great potential safety hazards, which may lead to serious consequences such as material dropping, equipment damage, and even casualties.

[0005] In addition, traditional lifting devices lack a flexible adjustment mechanism when dealing with materials of different weights and volumes, making it difficult to maintain balance and further exacerbating the risk of overweight and tilting. Content of the Utility Model
