Product Features and benefits:
High-Performance Powertrain: Engineered to reduce fuel consumption, this loader is equipped with a large-capacity torque converter. It collaborates with Komatsu’s SmartLoader Logic engine control system to automatically generate sufficient torque for each work phase, enhancing productivity.
Trusted Brake Cooling System: Enhance performance and confidence in load-and-carry situations with the front and rear brake cooling system of this vehicle.
Lower Fuel Consumption: Reduce idle time and save fuel with auto idle shutdown. Komatsu’s SmartLoader Logic utilizes data from various sensors to control engine torque based on job requirements.
Increased Operator Comfort: Experience a more comfortable ride with a new standard, heated, air-suspension seat providing enhanced support on rough roads. The large, quiet, pressurized cab ensures excellent visibility.
Ease of Access: Facilitate efficient maintenance with easy access through large, gull-wing-type engine doors and spacious steps on each side of the frame and front of the cab.
Increased Maneuverability: Designed to reduce operator fatigue, the Advanced Joystick Steering System (AJSS) allows for wrist and finger control of steering and directional travel.
Move More Material: Enhance power and control to handle substantial bucket loads with the large capacity bucket cylinder of this yard loader.
Optimized Capacity: The large capacity bucket is optimized based on material density, offering up to 9.8 yd3 capacity.
Stay Stable with Increased Ground Contact: 875/65 tires increase ground contact area, improving stability. The low profile reduces sidewall flex, providing more balance when dumping into trucks or hoppers.
