When your goal is maximizing your mining operation's productivity, it's all about cost per ton. The versatile WE1850 is engineered to improve both sides of the equation: lower cycle times and increased payload equates to higher productivity and more tons moved, with new multiple features designed to minimize your fuel and maintenance costs.
- Up to a 45% fuel consumption reduction*
- 35% CO2 reduction*
- Up to a 10-15% TCO advantage*
Note: *compared to mechanical loaders or hydraulic excavator 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.
Peak power on demand
The Kinetic Energy Storage System (KESS) works in concert with the SR Hybrid Drive to store significant horsepower captured from braking and direct it to supplement peak power demand. The result is fast cycle times without a commensurate increase in fuel usage.
Larger payload option available
Built for productivity. The WE1850-3 wheel loader can center load haulage trucks with payload ratings ranging from 240 to 360 tons.
Controls that support operator efficiency
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 maximize operator comfort.
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.
Hydraulics
The closed-center hydraulic system is designed to complement the SR Hybrid Drive system. Closed-center hydraulic systems are more efficient leading to lower parasitic horsepower loads on the engine, resulting in less fuel consumption and cooler operating temperatures to promote long hydraulic component service life.
Greenhouse gas reduction (Tier 4 compliance)
The SR Hybrid Drive system efficiency gains, from the regenerative braking and the energy storage system, reduce fuel burn, which can result in a substantial CO² reduction per ton of material moved as compared to a mechanical drive.
