1900AL Shovel

1900AL Shovel

  • Solid-state Magnetorque-based control system provides:
    • Fast cycle time
    • Minimized electrical inertia
    • Rapid motor response
    • Exceptional bail pull in the hoist function during severe-duty digging
    • Smooth, rapid dipper passage through the bank
    • Increased dipper fill factor without stalling

Contact your Joy Global representative for more information on the P&H 1900AL shovel.
