The specialists of Installcraneservice LLC have organized the launch of crane electrical equipment on the basis of thyristor resistance switches.


The key advantages of such type of controlling the crane mechanisms are:

the cost is not high compared to the “frequency control”;

steady rate (moment) at low rpm;

operation under the conditions of high dust concentration;

currentless commutation;

high overload capacity;

performance temperature range from -40 to +40.


Among the disadvantages are:

rather low adjustment range 1:10;

rigid determination of the mechanism speeds;

the efficiency factor of the electric drive is inferior to that received during the frequency converter control.
