WE1850
Make your operation its most productive
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
