Today’s new generation Joy loader was designed on the foundation of safety, durability and reliability found in the Joy continuous miner. It leverages several proven continuous miner designs including the Optidrive traction system, latest crawler chain, gathering gearcases and conveyor system technology.
The 14BU27 gathering arm loader, with up to 36 tonnes/minute (39.7 tons/minute) capacity, is designed as a utility machine for use in both production and auxiliary activities allowing great flexibility for your individual mine requirements.
Traction system
The 14BU27 includes our OptiDrive AC traction system, which is coupled to a compact, all-gear transmission to provide smooth, reliable service. The cutter motor feedback and the traction differential features optimize sump performance even in the most demanding applications. Finally, the brushless AC traction motors are highly reliable and require minimal maintenance.
Reduced noise
The 14BU27 features a SmartConveyor package, including our patented dual-sprocket conveyor chain, quiet tail, and hydraulic tensioning system. Pump/tank, bumper, and controller case isolators further reduce noise to provide a safer working environment for your operators.
Increased capacity and faster loading
The 14BU27 includes a 965 mm (38 in.) wide conveyor for maximum loading capacity, improving your overall productivity. The 14BU27 comes with 1500 mm (59 in.) diameter centrifugal loading arms (CLAs) improving productivity by maximizing loading capacity. Optional gathering arm style system is also available.
Reduced maintenance costs
The 14BU27 uses the same platform as our best-selling 14CM continuous miners, including the following components:
- Traction drives and traction chains
- Gathering head gear case and conveyor chain
- Electrics and OptiDrive
If your mining application includes both our 14CM continuous miners and 14BU27 loader, you can stock fewer replacement parts as well as leverage your existing maintenance knowledge to save both time and money.

Faceboss control system
Competitive and market pressures mean that you have to produce product at an ever-increasing rate, while always striving to decrease your cost per ton. These goals are only made more difficult by the worsening attributes of available reserves and deteriorating operating conditions.
The Faceboss control system enables your operators to operate equipment at an optimal balance of production rate and cost per ton using a powerful tool set that includes operator assistance tools, automated sequences, advanced diagnostics, machine performance monitoring, and analysis tools. Faceboss is the standard control system platform on all Joy underground mining equipment, which ensures that you receive the same level of optimization for all your Joy equipment.
OptiDrive AC
Joy OptiDrive, an AC variable-frequency drive system, integrates software with the electronic and mechanical systems to provide the following features:
- Increased tram speed: significantly increases the tractive effort available, improving the equipment’s ability to climb gradients and negotiate difficult roadway conditions
- Regenerative braking: supplements the mechanical brakes, allowing them to run cooler with extended wear life; regenerative braking is highly effective at automatically maintaining constant speeds when descending gradients
- Less maintenance: no commutator brushes to inspect and replace mean AC traction motors are typically more reliable, more durable, and require less maintenance than DC traction motors
