Shuttle car

21SC04

  • Rated load capacity 8 mt 9 st
  • Minimum seam height 123.1 cm 48.5 in
  • Conveyor horsepower 1 @ 25 kW 1 @ 34 HP

Built for low seam batch haulage

Designed for maximum production in low-seam applications with a robust drive system and reduced maintenance with a Joy OptiDrive AC variable frequency drive, due to no commutator brushes to inspect or replace.

  • Built for harsh conditions
  • OptiDrive designed to enhance performance
  • Range of models to fit your requirements
  • Engineered for maximum production

Features and benefits

Heavy-duty design

Designed for reliability with heavy-duty conveyor reducers and abrasion-resistant decking and chassis and rolling gears designed for optimal balance of volumetric load, vehicle dimensions, load-carrying ability and fatigue life.

A smooth ride

For uneven or broken roadways, Joy shuttle cars’ four-wheel independent suspension mitigates energy transferred to the chassis, designed for longer machine life and to help reduce operator fatigue.

Simplified maintenance

With a swing-out controller and swing-out pump compartment, easy access to hose and cables helps reduce maintenance time. Lighting options and zoned-out difficult-to-access grease points further facilitate maintenance.

Customizable conveyor system

Variable frequency drive (VFD) conveyor reduces the shock loading of all key conveyor drive components to help ensure the reliability and availability of the conveyor system. Operators can adjust discharge rates to match the mine belt infrastructure.

Permanent four-wheel drive

All-time four-wheel drive system helps performance on soft bottoms and grades. Powered by two 85kW VFD AC traction motors (50 kW in lower seam models).

Outstanding maneuverability

Four-wheel steering provides deft operation in narrow roadways. Non-suspension shuttle cars have crab steering, enabling an operator to turn all four wheels in the same direction for additional maneuverability.

Onboard cameras (optional)

Exceptional visibility using infrared or black-and-white cameras. One forward and one rearward-looking monitor are mounted in the operator’s compartment.

Improve air quality

To help supply clean air for your operators, positive pressure is maintained by a hydraulically powered motor operating both blower and air conditioner in the operator compartment. Filter improves air quality. Available as an OE option on new cars, or a kit for existing cars.

Remote control to extend your operations

An optional remote-control system can increase productivity of your room and pillar operations. An unmanned shuttle car can follow a continuous miner under an unsupported roof section, allowing for deeper cuts.

Rated load capacity*

8 tonnes

* The rated load capacity listed for each shuttle car model is the maximum amount the drive train and chassis are rated to haul. The actual carrying capacity is dependent on numerous factors, including but not limited to, the conveyor width, the sideboard height, the density of the material as conveyed, the ability of the continuous miner to load into the shuttle car, and the mining height. Certain  combinations of sideboard height, conveyor width, specific density of the material being transported, and floor gradient can exceed the allowable load rating of the car. Consult Engineering before ordering.
