New | 973D SH Shiphold/Port Handling

Time is money. Optimizing the unloading time is what it is all about when it comes to machine selection. You can load many types of machines inside a shiphold but none would provide the perfect match for the application as the Track-Type Loader can thanks to the combination of tracks giving traction, loader arm for the reach and engine at back for the machine balance.

Shiphold/Port Handling

Infinite Variable Speeds (hydrostatic transmission)

  • Smooth controls, more operator comfort
  • Increased operator productivity

Joysticks for Transmission and Work Tools

  • Easy to maneuver
  • Intuitive controls minimize training requirements

High Reach Work Tool

  • Loader arm allows cleaning of the walls of the hold
  • Increases versatility of the machine

Track-Type Undercarriage

  • Low ground pressure for better traction in some materials
  • Several shoe widths available or can be manufactured at order to meet customer requirements
  • Optional center hole shoes reduce track packing and track chain tightening which extends undercarriage life

Lifting Eyes

  • Front eyes welded on the Track Roller Frame (TRF)
  • Rear eyes mounted on the main frame
  • Wide spacing for good stability during lifting


  • Sound suppressed cab and air suspended seat reduce operator fatigue and increase concentration
  • The sound levels measured per ISO 6396 reach 77 dB(A) for 973D


  • Large windows all around operator and clipped engine enclosure provide excellent view to the environment and the work tool
  • Day and night operations are lighted with 8 halogen lights: 4 lights facing frontward, 2 lights facing rearward and 2 facing sideways

Rear Engine and Cooling System Location

  • Improved machine balance
  • Engine less exposed to dust, increase engine life
  • Limit plugging of radiator core
  • Better visibility at front
  • Reduce O&O cost

Reversing Fan

  • The air flow can be either automatically or manually reversed. Maintains proper heat transfer by blowing material out of the radiator core.
  • The hinged radiator grill gives easy access to the cooling system of the machine

Heavy Duty Bumper

  • Gives outstanding protection for the rear of the machine
  • Cooling system is well protected in case of accidental impacts with a wall of the shiphold

Maintenance and Serviceability

  • Filters and other systems are accessible from the ground on each side of the machine
  • Cab can be tilted 90° with a crane or 30° with a hydraulic jack allowing job site repair
  • Makes the maintenance of the machine easier for engine or hydraulic components

Engine Air Precleaner

  • Debris is centrifugally removed from the airstream and delivers cleaner air to the engine filter
  • Air filter life is extended

Designed to meet your needs

Work Tool Options

  • Pin-on trim blade for all material
  • Pin-on trim blade for coal
  • Pin-on general purpose bucket
  • Pin-on multi purpose bucket
