Make an order

Cylindrical three-stage vertical crane gearbox type B (C3VK-100, C3VK-125, C3VK-160, C3VK-200, C3VK-250) is designed for use in lifting and transport equipment, as well as a general purpose drive.

C3VK(F) – a model installed in inclined and vertical positions. It is possible to manufacture on the flange. Their main task is to reduce the frequency of revolutions of the motor shafts and increase the torque. These reducers are used in the mechanisms that provide movement for lifting cranes, as well as crane trolleys.

Terms of use:

  • the load is constant and variable in one direction and reversible;
  • work is long or with periodic stops;
  • rotation of shafts in any direction;
  • the rotation frequency of the input shaft must exceed 1800 rpm;
  • atmosphere of types I and II according to GOST 15150-69 with air dust content of no more than 10 mg/m3;
  • climatic versions: U, T (for accommodation categories 1…3), UHL and O (for category 4) according to GOST 15150-69.
