Special crane reducers VKU-610M … VKU-965M

Gear three-stage vertical general-purpose special crane reducers of the VKU type (VKU-610M, VKU-765M, VKU-965M). People install them on the travel mechanisms of cranes and other machines that operate in crane mode. The SKU crane reducer is considered the most popular and used in modern engineering.

Special crane reducers – 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%.
