Make an order

Cylindrical crane gearbox RK (RK-500, RK-600) is intended for use in lifting and transport equipment, as well as as a general-purpose drive.
Mechanisms of the RK series are indispensable in production, in particular when working with lifting cranes. The main purpose is to change the rotation speed of the shafts, as well as the input and output torques. The reducer is installed in the upper part of the crane or as a mechanical drive.

Conditions of use:

  • the load is constant, variable, reversible or in one direction;
  • work with stops and long (around the clock);
  • rotation in either direction;
  • primary shaft rotation frequency up to 1500 rpm;
  • atmospheric conditions of type I and II according to GOST 15150-69 with air dust content of no more than 10 mg/m3;
  • climatic versions U, T for placement categories 1-3 and climatic versions UHL and O for placement categories 4 according to GOST 15150-69.
