KOMATSU WA500-7 wheel loader

  • Feature
  • Parameter
Large capacity torque converter with lock-up: • Reduces fuel consumption • Faster top speed • Quick acceleration • Lock-up in 2nd, 3rd and 4th gear Komatsu SmartLoader Logic helps reduce fuel consumption with no decrease in production. A powerful Komatsu SAA6D140E-6 engine provides a net output of 263 kW / 353 HP with 7% improved fuel consumption. This engine is EPA Tier 4 Interim and EU stage 3B emissions certified. Komatsu Variable Geometry Turbocharger (KVGT) uses a hydraulic actuator to provide optimum air flow under all speed and load conditions. Komatsu Diesel Particulate Filter (KDPF) captures 90% of particulate matter and provides automatic regeneration that does not interfere with daily operation. Increased cooling capacity • Auto-reversing fan is standard • Wider core coolers An all new cab provides the operator with improved comfort and visibility. New high resolution monitor panel • Enhanced and intuitive on-board diagnostics • Integrated with KOMTRAX Level 4 • Integrated with Komatsu Tier 4 technology Rearview monitoring system (standard) New high capacity air suspension seat • Seat mounted EPC controls with F-N-R switch • Seat heater is standard Energy saving guidance • Six operator guiding messages • Enhanced eco-gauge Komatsu Auto Idle Shutdown helps reduce idle time and reduce operating costs. Remote boom and bucket positioners can set kick-outs from inside the cab. Variable displacement piston pumps with CLSS help reduce fuel consumption. KOMTRAX equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more.
