Versatility
Regardless of the direction of mining, both main and auxiliary drive frames are designed by Bucyrus so they can be used in either a left-hand, or right-hand longwall face.

Main and Tail Drives

The drive frames of the high-performance systems are an important element of the conveyor. At either end of the conveyor, they provide the mount for the chain sprockets which transmit the drive power of 2 x 1200 kW at the main drives and 1 x 1200 kW at the tail drive.

Both drive frames are designed that, regardless of the direction of mining, they can be used in a left or right-hand longwall faces.

Main Drive
Main drive
  • Transfer at main drive via cross-frame, side removal, front removal or rollcurve

  • Dimensioned for a conveyor capacity of up to 6000 t/h
Auxiliary Drives
TAIL drives
  • Installed power up to 1200 kW
  • Tensionable drive with up to 1.0 m stroke to prevent slack chain and high wear
  • Automatic setting of optimum chain tension during operation
  • Maximum chain life and minimum conveyor downtime for double caut
