  • *Compared to mechanical loaders or HEX machines

Features and benefits

Fuel efficient SR Hybrid Drive

The SR Hybrid Drive system is fully regenerative. During braking or retarding, electrical motors become generators and feed power back into the electrical system. This allows for up to 45% less fuel consumption than comparably sized mechanical drive wheel loaders.

Largest available payload option

Built for productivity. The L-2350 wheel loader can center load haulage trucks with payload ratings ranging from 320 to 400+ tons.

Peak power controls that support operator efficiency on demand

The LINCS II network control system provides instant, real-time feedback and vital statistics, such as bucket height and angle, individual bucket payload, and total tons moved. All of it helps your operators maximize productivity by adjusting to conditions.

Attuned to operator comfort

The spacious, environmentally controlled cab offers great visibility, a comfortable ride and room for a trainer seat. Digital joysticks give your operators easy and responsive control, while the highly adjustable, heated/cooled seat helps minimize driver discomfort.

Fast, efficient maintenance

Multiple design features help keep your maintenance costs low: the integrated, patented drive system has few components resulting in longer maintenance intervals, multiple access points mean faster component change-out times and more uptime for your machine.

Handles multiple site duties

If your operation involves frequent equipment relocations, you’ll love this loader. It can keep the pit floor clean and level without support equipment, offers outstanding mobility and travel speed, and handles berm maintenance, road repair and cutting ramps.

Structural

Frames are fabricated from high strength, low-alloy steel with excellent weld characteristics and extreme low temperature properties. The front axle is an integral, fixed part of the front frame. The rear axle center oscillates 12.5 degrees.

Unique forged ball and socket joints are utilized in multiple pivot locations (lift arms, rear axle, frame articulation, hoist cylinders). These joints are superior in absorbing and distributing multi-directional stresses. Features easily replaceable brass liners for long life and easy maintenance.

High strength castings are used in key areas of fabricated structures to reduce stress and improve structural life.

Technology that works as hard as you do

Wheel Loader_WE1150_GPL10420_new_Yellow bucket.psd
Komatsu’s ties to SR Technology date back to the beginning. SR is the future, but it’s been part of Komatsu’s for a long time. Everything we did has been built on decades of work and experience. Not only can we offer the benefits others are beginning to scratch the surface on, but we know how to apply this technology and optimize every bit of reliability, fuel efficiency and performance.
WE1250
Komatsu’s new Electric Drive Innovation Center focuses on expanding the capabilities of SR Technology. It may seem like breakthroughs come out of nowhere, they certainly did not. They are born out of years of hard work and they happen in places like Komatsu’s new Electric Drive Innovation Center located in Longview, Texas, U.S.

The SR (Switched Reluctance) hybrid drive system captures and uses regenerated energy, helping to reduce a machine’s overall fuel consumption and wear and tear on mechanical parts.
