About the Caterpillar WE-851B Windrow Elevator (8BC)

The Caterpillar WE-851B is a high-capacity windrow elevator engineered for maximum material transfer in continuous, high-speed paving operations. Designed to work in tandem with Caterpillar’s largest asphalt pavers, the WE-851B features a widened pickup design that efficiently lifts massive asphalt windrows and delivers them to the paver hopper without segregation or cooling. A hallmark of the 8BC series is its reinforced conveyor frame and high-torque hydraulic motors, which are built to handle the abrasive nature of hot-mix asphalt under extreme production demands. With its adjustable pickup height and responsive material flow controls, the WE-851B remains the industry standard for contractors who demand peak reliability on major highway expansions and airport runway projects.

Maintaining an 8BC-prefix elevator requires access to accurate factory specifications to handle its heavy-duty conveyor drives and synchronized hydraulic circuits. This manual ensures that every task—from replacing conveyor slats to calibrating hydraulic pressure—is performed to original equipment standards. Investing in this digital guide protects your equipment investment and ensures the uptime needed for professional paving contracts.
