HEALTH MONITORING
  • A comprehensive health monitoring system is available, including oil levels and temperatures, flows, pressures and vibration analysis.

VIBRAGUARDTM
  • VibraGuard allows trained personnel to predict machine component wear, avoid unplanned downtime and set alarms to warn the operator if monitored machine components run the risk of damage. This comprehensive protection backs long life and high availability of your valuable mining equipment. • Permanent online monitoring: – Replacing sporadic offline measurements, permanent online monitoring provides extensive protection and helps predict component wear. Alarms warn the operator if monitored components are at risk of damage. • Reduces unplanned downtime: – When utilized by trained personnel, VibraGuard makes repairs predictable and helps avoid unplanned downtime. This allows timely procurement of spare parts and stress-free repair. • Data analysis: – Data is transferred to a surface control center PC for detailed analysis and evaluation.

COAL SIZER
  • Cat shearers can be supplied with an optional rugged coal sizer, currently with up to 200 kW (268 hp) of installed power for maximum productivity in high seams or difficult mining conditions. The coal sizer can be ordered separately for installation during rebuild or overhaul.
  • Optional Machine Mounted Coal Sizer – CS200: • Transmission rating of 200 kW (320 hp @ 60 Hz) • Quillshaft transmission protection • Drum speed of 200 rpm (240 @ 60 Hz) • Drum diameter 900 mm (35.5 in) over picks • Integral water cooling for transmission and motor • Square drum hub drive for drum • Complete with anti-shock lift mechanism (unique to Caterpillar) • Available motor rating 200 kW @ 50 Hz (320 hp @ 60 Hz)

SPECIALIZED SHEARERS
  • Caterpillar also supplies shearers for specialized applications: • Single- and double-drum low-seam shearer • Three-drum shearer for selective mining These shearers utilize the key feature of modular mainframe construction and are proven for coal and non-coal applications.

A Commitment to the Mining Industry

As the demand for commodities grows, mining companies need a partner to support them in their efforts. Caterpillar is committed to being that partner.
