Cylindrical crane reducers C2-250 … C2-1000

Two-stage cylindrical crane reducers C2 (C2-250, C2-300, C2-350, C2-400, C2-500, C2-650, C2-750, C2-1000) are used in lifting machines. As well as for changing torques and rotation frequency as a component of various types of mechanisms.

This standard size is suitable for use in temperate climates (U). As well as in arid and humid tropical regions (T). It can also be used outdoors under a canopy or in closed rooms with a regulated microclimate.

Cylindrical crane reducers – conditions of use:

• rotation of shafts in both directions;
• climatic conditions U, T, accommodation category-2,3 according to GOST 15150-69;
• non-aggressive environment, moderate dustiness and humidity;
• input shaft rotation frequency – no more than 1500 rpm;
• the recommended use is the range of gear ratios from 8 to 50.
