Overview

What if you could have the class-leading payload and superior productivity of the proven Cat® R1700 underground loader without the engine heat or exhaust emissions? You can. Introducing the R1700 XE battery electric LHD—a high-productivity, zero exhaust emission loader with the industry’s only onboard battery. It charges quickly—in less than 20 minutes when paired with two of the durable and mobile Cat MEC500 chargers. This provides an alternative to expensive static charging station infrastructure, as well as the need for additional batteries, battery handling and battery swapping. The machine also features Autodig for optimized loading and is factory-ready for autonomous operation. And it delivers the powerful performance, maximum uptime and low operating costs you demand.

Please note that model availability may vary by region. Contact your local Cat dealer for details on models available in your area.
