What is an infinitely variable speed tower crane?

The infinitely variable speed tower crane is a tower crane driven by an infinitely variable speed motor.

The biggest difference between CVT and common hydraulic automatic transmission is in structure. The latter is composed of hydraulically controlled gear transmission system, which can realize stepless speed change between two gears, while CVT is composed of two sets of speed change wheels and a transmission belt, which is simpler in structure and smaller in size than traditional automatic transmission.

The origin of continuously variable transmission and automatic transmission

Automatic transmission is born for simple operation and reducing driving fatigue. According to the control mode of gear transmission system, it can be divided into hydraulic automatic transmission and electronic hydraulic automatic transmission; According to the change of transmission ratio, it can be divided into stepped automatic transmission and stepless automatic transmission. Therefore, CVT is actually a kind of automatic transmission, but it is much more complicated and technologically advanced than the common automatic transmission.

CVT can change the transmission ratio freely, so as to realize the whole stepless speed change, which makes the speed change more stable, without the feeling of "sudden" when shifting gears in traditional transmission.
