○ outstanding performance

○ Efficient and safe

○ Save time

○ Faster at light loads

○ Cranes equipped with ESR (Extended Speed) function always automatically adjust the speed so that the rated power is fully utilized.

○ In the case of lifting light and small goods, the surplus power part of the motor is used to increase the running speed, thereby improving productivity.

○ For a crane with ESR function, the operating state of the crane under heavy load and light load is very different; depending on the actual load, the system continuously performs independent calculations during the operation process, making it fully match the load requirements and ensure lasting safety.
