L68A1 Mast SectionWhat things need to be done in the design of tower crane lifting device
According to the operation process of the tower lifting operation, the installation of the non-cylinder type overlifting device is simple and fast, but there are many things to pay attention to during the use process, and the operation technology is difficult. Horizontal + vertical cylinder type overloading device has complex structure, high cost, and time-consuming assembly, but it is convenient to use, flexible operation, and can achieve super-weight allocation without stage variation; The horizontal cylinder type is easier to install than the former, and the cost is low. However, the use performance is similar to that of the non-cylinder type, but it can have no stage variation after overloading. Vertical cylinder type overlift device is relatively horizontal + vertical cylinder type structure is simple, the cost is low, the assembly time is similar, and the use is also relatively convenient.
