Product Features and benefits:
High-Performance Powertrain: Benefit from a large-capacity torque converter, coupled with the Komatsu Smart Loader Logic engine control system. This combination automatically generates ample torque for each work phase, effectively reducing fuel consumption without compromising production levels.
Brake Cooling System: Enhance performance efficiency and gain added confidence in load and carry situations with the front and rear brake cooling system.
Low Fuel Consumption: Mitigate fuel consumption by minimizing idle time through auto idle shutdown. The Smart Loader Logic system utilizes data from various sensors in the loader, adjusting engine torque based on job requirements.
Comfortable Operator Environment: Improve operator comfort with a new standard heated, air-suspension seat that offers enhanced support on rough roads. The large, quiet, pressurized cab ensures excellent visibility for the operator.
Ease of Access: Facilitate efficient maintenance with easy access provided by large, gull-wing-type engine doors and spacious steps on each side of the frame and at the front of the cab.
Advanced Joystick Steering System (AJSS): Combat operator fatigue with the Advanced Joystick Steering System (AJSS), designed to enable wrist and finger control for steering and directional travel.
