Adaptable Modular Design:

• The Joy shearer features a versatile modular design, consisting of three high-tensile fabrications forming a slim main section without an under-frame.
• Eliminating the under-frame enhances material passage, simplifies transport, enables quick adaptation to various mining scenarios, facilitates efficient rebuilds, and simplifies maintenance.

Rigorously Tested Gear Design:

• Rely on the outstanding reliability of the shearer with rigorously tested gear design in the ranging arm and haulage gear trains.
• Robust spur gears, incorporating decades of experience, coupled with state-of-the-art gear design software and meticulous load-testing, contribute to the enhanced reliability of the Joy shearer.

Haulage Sections Built to Exacting Standards:

• The primary haulage gear case, mounted to both sides of the controller case, adheres to exacting standards.
• Inside the gear case, straight-cut spur gears manufactured with precision ensure that the 7LS shearer can match tractive effort increase delivered by higher power-density motors.

Custom-Designed Drums:

• Elevate your operation with custom-designed drums manufactured using a three-axis digital lacing machine, resulting in precise bit locations and angles.
• Final machining with CNC turning centers ensures a precise fit, demonstrating the difference custom-designed drums can make.

Choose the Best Cowles Blade for Your Site:

• Tailor your shearer with a choice between “T” style or “D” style Cowles blades, each offering unique advantages.
• “T” Cowles blades, more compact, may perform better in drum loading, while wider “D” Cowles blades are stronger and can withstand harsh conditions more effectively. 

Easy Access Controller Case:

• The central controller case houses the electric control system and features easy gob-side access for maintenance in a safer working environment.

Automated Cutting Sequences:

• Achieve highly efficient cycle times, consistency, and reduced operator exposure with fully programmed automated cutting sequences, including gate end turnarounds.
• Automation software optimally positions the drum, maintaining a pre-configured pitch angle to the pans.

Simple, Reliable Remote Operation:

• Operate the shearer remotely using the HHX remote, employing reliable two-way radio communication for control.
• The integrated LCD screen displays operational and diagnostic information, and a removable, large-capacity battery pack allows for extended intervals between charges. 

Optional Trapping Shoe Inserts:

• Enhance production efficiency and reduce operating costs with Komatsu trapping shoe wear inserts.
• These inserts increase the time between shoe replacements, providing a cost-effective solution that is relatively simple to install at only 32 kg (70 lbs.).

OptiDrive System:

• The OptiDrive system offers an adaptable, rugged, and reliable transmission design for shearer traction systems.
• Integrating the variable speed drive with the motor ensures outstanding speed and torque control for soft starts, stops, and fast acceleration.

Faceboss:

• Optimize your operation with actionable insights, operator assistance tools, automated sequences, advanced diagnostics, and machine performance monitoring provided by the Faceboss Control System.

Advanced Shearer Automation:

• Increase productivity and reduce operator exposure to dust and noise with the latest shearer steering technology, offering access to fully automated cutting sequences, including gate end turnarounds.
