Due to today`s economic problems, the demand for universal lifting and transporting vehicles with high efficiency is high in manufacturing plants, logistics centers, warehouses, etc. There are many problems that need to be solved in order to increase the efficiency of lifting and transporting vehicles. Maintaining and controlling their longitudinal and lateral balances during operation is one of the important issues that still need to be addressed. They also include reducing the turning radius of the vehicles and thereby increasing the efficiency of the vehicles, as well as industrial enterprises and warehouses. The article analyzes several types of patents and research papers related to the variable center of gravity. In this case, the study was divided into groups according to the proximity of the directions in the patents. The advantages and disadvantages of the development of lifting and transporting vehicles with adjustable gravity centers, as well as the work that needs to be done, were discussed.
