Additional Information
The Chelsea 880 Series is designed for heavy-duty on-highway and off-highway applications where high torque and reliable continuous operation are required. Typical applications include bulk haulers, fire trucks, oil field equipment, aerial units, winch installations, and large truck recovery vehicles. The 880 Series is available for a wide variety of transmissions, including the Eaton Endurant, and supports SAE B, SAE C, and ISO 7652 pump flange output configurations across the series family. The standard lever shift can be paired with optional air control shift configurations depending on the specific model ordered. Tapered cone bearings provide load-bearing capability suited to the demands of these applications.
