Komatsu America Corp.’s WA380-6 wheel loader delivers optimum fuel efficiency, operator comfort and reliability. Designed for sand and gravel, commercial and industrial applications, the WA380-6 employs the latest technological advancements, which enable operators to work comfortably and productively in a variety of conditions.

The WA380-6 has a net power of 191 hp (143 kW) and an operating weight between 38,760 and 39,600 lbs. (17,581 and 17,962 kg). All major components, including the engine, torque converter, transmission, hydraulic units and electric parts, are engineered and manufactured by Komatsu under a strict quality control system. The wheel loader has a general purpose bucket capacity of 3.8 to 5.2 cu. yds. (2.9 and 4 cu m), and a dumping clearance of 9 ft. 8 in. (3 m) with the standard bucket.

The WA380-6 is equipped with KOMTRAX technology, which sends machine operating information to a secure Web site utilizing wireless technology. Data such as fuel consumed, operating hours, working hours, location and maintenance alerts are relayed to the web application for analysis. The KOMTRAX fleet monitoring system increases machine availability, reduces the risk of machine theft, allows for remote diagnosis by the distributor and provides other information to drive business efficiency and productivity, according to the manufacturer.

Special features of the wheel loader include:

Fuel Efficiency for Optimal Productivity

The WA380-6 gets its work capacity from a Komatsu SAA6D107E engine with an electronic heavy duty common rail fuel injection system. The wheel loader’s fuel consumption is greatly reduced because of the low-noise, high-torque engine combined with closed-center load sensing system (CLSS).

With two selectable operating modes that are easily adjustable, the engine effortlessly adapts to different working conditions. The E mode provides maximum fuel efficiency for general loading and the P mode has a maximum power output for hard digging operation and hill climbing. For load and carry or hill-climb operations, the torque converter with optional lock-up transmission provides increased production efficiency, reduced cycle times and optimum fuel savings. An Eco Indicator informs the operator when the machine is maximizing fuel efficiency.

Large Cab

The WA380-6 was designed to make it safe and easy for operators to work a full day, increasing productivity. The cab’s low-noise design of 72 dB(A) creates a comfortable working environment. The new roomy cab is mounted with Komatsu’s viscous mounts to keep noise at a minimum and provide a low-vibration, clean operating environment. The layout of the cab provides easy access to levers. The air conditioner is located at the front of the cab to increase seat reclining and backward slide adjustment. In addition, the wide pillar-less flat glass provides excellent front visibility.

PPC control levers have been implemented so that the operator can operate the work equipment with fingertip controls, reducing fatigue and improving fine work equipment control and productivity. The work equipment lever console can be moved forward or backward and the large arm rest can be adjusted up or down to provide the operator with a variety of comfortable operating positions.

The automatic transmission with electronically controlled modulation valve (ECMV) makes operating functions easier and more efficient and ensures a more comfortable ride. It automatically selects the proper gear speed based on conditions such as travel and engine speed, and includes two switches that make operating the machine easier. With the touch of a finger, the kick-down switch automatically downshifts from second to first when beginning the digging cycle; in reverse, it automatically upshifts from first to second. Conversely, the hold switch keeps the transmission fixed to either the third or fourth gear speed when auto shift is selected.

Easy Maintenance

To reduce costly downtime, the WA380-6 wheel loader was designed for easy service and maintenance access.

The WA380-6 is equipped with the Komatsu equipment management monitoring system (EMMS). The easy-to-read monitor keeps the operator informed of all machine functions, including fluid and filter change intervals and troubleshooting memory display functions. An automatic reversible automatic hydraulic radiator fan allows the operator to quickly clean out the cooling system at preset intervals or with the flip of a switch.
