1, through the frequency converter speed control is the most ideal variable frequency speed regulation method, can realize stepless speed regulation, and also has higher control accuracy, can remote operation, easy to use and maintenance. But it is important to note that using a conical motor electric hoist the general use of inverter, because all inverter starts when the need to speed up the time, when accelerating voltage is slowly rising, the moment can not make shift conical rotor brake release, easy to cause the inverter overload protection.
2, the motor rotor resistance speed control, its advantages are simple structure, low price, quality in general, and its shortcomings is that the speed change is relatively large, unstable.
3, the hydraulic push rod speed, can achieve a stable speed, but the speed is low, intermediate tecshare soft, and must carry on the transformation of the electric hoist machinery parts when in use.
4, through the power brake speed control method, is characterized by speed, gear can be adjusted, and high energy saving, safe and reliable use, the disadvantage is that the low speed is not sure.
The daily use of electric hoist process, the speed of electric hoist calls directly affect the efficiency of construction machinery production, mountain Yan group reminded you to choose according to different electric hoist suitable speed regulation method.
