INTRODUCTION:

• The Marion 151-M is a medium sized shovel or dragline using a direct current
  Ward-Leonard system with individual exciter control for powering all
  motions. The machines to be covered by these instructions use General
  Electric Co. “Amplidynes” as the individual exciters.
• The motor generator set (M. G. set), mounted at the back of the machine, is
  driven by a 3 phase alternating current induction motor. The incoming alternating
  current voltage is stepped down through transformers for operating the
  auxiliaries such as the air compressor, blowers, oil pumps and lights.
• The generators driven by the induction motor are the exciter, the hoist generator,
  the swing generator, and the crowd generator. The exciter furnishes excitation
  for the Amplidyne control fields and the motor shunt fields. The generators
  furnish power for the main D. C. driving motor armature circuits.
• The hoist, swing and crowd Amplidyne units, which furnish the excitation for
  the generator separately excited fields, are mounted in the D. C. cabinet.
• The hoist motor, a horizontal mill type, D. C. motor, furnishes power for the
  hoist drum and propel gears through a double gear reduction. The crowd
  motor, also a horizontal mill type, D. C. motor, is mounted on the boom and
  drives the crowd rack pinion through a gear train. The two swing motors are
  vertical mill type, D. C. motors, furnishing power for swinging through two
  sets of gears.
