How to choose electric Wire rope hoist

How to choose  Wire rope hoist 
In the daily use of the process of  rope hoist ,  rope hoist operating speed for pay particular attention, because the speed of the call directly affect the efficiency of the production of construction machinery, here offers several more practical rope hoist speed control method for you to save time, create more productive value.
1, the motor rotor resistance control, the advantage of simple structure, low prices, quality in general, and its deficiency is relatively large changes in speed, unstable.

2, through the hydraulic pusher for speed, you can get a relatively steady rate, but its speed is low, in the middle of the soft Xpress, but when in use must be carried out for rope hoist mechanical components part of the transformation.

3, through the dynamic braking speed control method is characterized by the stall speed can be adjusted, and high energy efficiency, safety and reliability, the disadvantage

lies in the low grasp not.

4, through the inverter, which is an ideal frequency control method that can realize stepless speed regulation, but also has higher control precision, easy to use and maintain,

and can also be operated remotely.
