Special crane reducers VK-350… VK-550

Vertical three-stage special crane reducers VK-350, VK-475, VK-550 are intended for use in drives of crane movement mechanisms. People operate reducers in areas with a moderate (climatic version U), dry and humid tropical (T) climate, placement category 2 according to GOST 15150.

Special crane reducers VK-350… VK-550 – terms 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%.
