Abstract: A control system for a super-lifting device of a crane comprises a pressure-detecting element (21) for detecting the pressure of a variable amplitude oil cylinder and obtaining a measured pressure value, and a control element (22) for comparing the measured pressure value with the predetermined pressure value. When the measured pressure value is larger than or equal to the predetermined pressure value, the tensioning oil cylinder (23) is shortened, therefore increasing the tensioning pressure of the tensioning oil cylinder (23), reinforcing the tension of the super-lifting cable wire in the super-lifting device, and increasing the super-lifting moment applied to the main arm by the super-lifting device, which can effectively balance the pressure of the variable amplitude oil cylinder. A control method and a super-lifting device with the above control system are disclosed.
