Focusing on frequency conversion speed regulation, it can provide lifting frequency conversion, running frequency conversion or lifting/running full frequency conversion according to customer needs, or optional lifting overspeed protection function, the standard configuration is lifting frequency conversion double speed.

◇ Environmental protection type:
c. Low noise, about 5dB(A) lower than ordinary CDK/MDK type hoist, improving the working environment;
d. Environmentally friendly paint, less pollution to the environment;
e. There is no asbestos in the parts and materials to protect the health of the operator;

◇ Reliable work, improving the service life of wearing parts:
a. The limiter adopts an off-control type, and two limit switches can be used in the upper limit position, the limit action is more reliable;

◇ Use a dedicated hoist frequency converter for speed regulation when lifting two speeds:
a. Work smoothly, with little impact during starting and braking;
b. High-efficiency and energy-saving. According to the test of the authoritative department, the energy efficiency value of the variable frequency hoist of the same specification is increased by about 10% compared with the ordinary hoist;
c. Speed adjustment is convenient, users can adjust the lifting speed as required, and the adjustable speed range is 10% to 100% of the rated speed at 50Hz.
