Ecology, economy and strength

WA430-6

Operating weight 20,000 kg (44,100 lb)
Net flywheel power (SAE) 231 hp (172 kW) @ 2,100 rpm
Bucket capacity (SAE) 3,5 m³ (4,3 yd³) @ 1,6 t/m³

Technology and comfort

Provides an excellent work environment for the operator due to its automatic transmission with ECMV (Electronically Controlled Modulation Valve), an electronically controlled transmission lever, a variable transmission cut-off system, a tiltable, telescopic steering wheel and manually controlled joysticks. The cab also has a low-noise design, a big pillar-less ROPS/FOPS, and back hinged easy-access doors.

Features

Variable displacement piston pump and CLSS

The variable displacement piston pump with its Closed-center load Sensing System (CLSS) provides the hydraulic flow demanded by the application or effort performed, reducing hydraulic pressure waste to minimum. Reducing waste improves fuel saving because the engine just produces a specific level of rpm only to satisfy the requirements.

Kickdown switch

The kick down switch is a valuable feature to increase productivity. With just a switch, the operator can shift down when the excavation cycle begins, meaning less wasted time on shifting gears and, therefore, reduced cycle times. Then, the system shifts automatically from F1 to F2 when the traveling control lever is changed to reverse.

Ecology & Economy - Technology 3

Komatsu, following its Ecology and Economy policy, continues to develop engines with high performance low-emission technologies, complying with the most rigorous environmental standards, such as the new EU Stage 3A and EPA Tier III emission regulations (equivalent).

With this technology, Komatsu introduces its new ECOT-3 engines with total electronic control system; fuel injection (Heavy-duty and high-pressure common rail); exhaust gas recirculation (EGR); air to air aftercooler and a new combustion chamber design; and NOx, PM and fuel consumption reducing systems.
