With the rapid development of modern construction industry, hydraulic climbing formwork system has many advantages, such as high efficiency, good economy and so on, which occupies the leading position in construction of super high-rise building. Among them, the steel platform formwork system lifting hydraulic system is the key part of the equipment. Due to the large volume, large weight, large inertia of the formwork system, electrohydraulic proportional technology and PID control technology were adopted in the top lift hydraulic system design.The reliability and safety of the whole system are ensured effectively.
