What are the advantages and disadvantages of single cylinder and double cylinder?

The single-cylinder straight-top cylinder has high cost, large cylinder stroke, generally multi-section cylinders, and the manufacturing process of the lifting mechanism is relatively simple;

The single-cylinder compound lifting mechanism is more complicated and requires higher assembly process, but the cylinder stroke is small and the structure is simple, and the cost is low. These two forms of lifting mechanism are in better stress condition. The double cylinder is generally in the form of a straight top such as EQ3092, which has a simple structure and low cost, but the stress condition is poor.
