They allow the mechanism to function even under the highest loads

Make an order

Gear three-stage vertical general-purpose crane reducers of the VKU type (VKU-610M, VKU-765M, VKU-965M) are installed on the movement mechanisms of load-lifting cranes and other machines that work in crane mode. The SKU crane reducer is considered the most popular and used in modern engineering.

Conditions of use:

  • constant and variable, unidirectional and reversible load;
  • work is constant and with periodic stops;
  • rotation of the shafts in any direction without advantage at a speed of rotation of the high-speed shaft up to 1000 revolutions per minute;
  • ambient temperature – from -40 0 C to +50 0 C;
  • increased dustiness, non-aggressive environment;
  • humidity at a normal temperature of 20 0 C – up to 95%.
