Description
This is a series of coal combines c electrical supply part. They have a built-in motor movement and a transverse recess coal. The total installed capacity of 700 kW. This cutting 2x300 kW electric motors, electric supply of the 2x40 kW and height adjustment of 18.5 kW. Combine supply voltage 1140 V or 3300V. The machine is equipped with a frequency converter type "one tow - two ways to" control the feed rate frequency conversion alternating current and applied to the rack engagement. The combine is designed for operation in seams between 1.7 and 4.7 m at the corners of less than 16 ° (two-quadrant converter) or less than 35 ° (a four-quadrant converter) and medium strength of coal in the fully mechanized coal face.
Serial type includes:
Shortened type: MG300/700-AWD, MG300/700-QAWD
Standard Type: MG300/700-WD, MG300/700-QWD
Limit type: MG300/700-GWD, MG300/700-QGWD
