Overview
Optimal Productivity. Zero Exhaust Pollution.
What if you could benefit from the highest payload in its category and the optimal productivity of the proven CAT® R1700 underground loader, without the heat from the engine or exhaust emissions? You can. Introducing the R1700 XE electric battery loader - a high-productivity loader with no exhaust gas emissions, featuring the industry's only onboard battery. It charges quickly, in less than 20 minutes, when paired with two durable and mobile Cat MEC500 chargers. This is an alternative to costly static charging station infrastructure, as well as the need for additional batteries, handling, and swapping. The machine is also equipped with Auto Dig for optimized loading and is factory-ready for autonomous operation. And it delivers the powerful performance, maximum uptime, and low operating costs you demand.
AdvantagesBattery-Powered
With 100% battery-powered propulsion, no exhaust emissions, and significantly lower heat production.
Production Priority
With a 15-ton payload, performance equivalent to the R1700, and optimized loading with Auto Dig.

Security
Improved visibility, thanks to lighting and camera coverage, including the optional rearview camera with color screen, and standardized LED lights that provide front and rear lighting. Factory-ready for fire suppression, dedicated area for fire extinguishers, and multiple fire suppression activation points, including from the cabin. Improved access and egress with non-slip strips on all walking surfaces, a newly designed handrail system with full coverage, and two emergency exits. Driver presence detection system, which protects the machine and the driver from uncontrolled movements of the equipment, with hydraulic circuit neutralization and door sensor. A safer service with integrated lockout/tagout points, front linkage pins to lock the lifting arms in place, and bolted towing hooks.
Mastering and Driving Comfort
Completely redesigned cabin offering more space, with a lower seated driver for better driving quality and more headroom, adjustable padding for the driver's knees, and more space for foot comfort when using the pedals. Standard air conditioning with pressurized speaker option; all-new HVAC cover with improved airflow, larger defrost coverage, and reduced noise levels. Improved ergonomics on all controls, easy-to-use manipulator controls, and cabin mounted on silent blocks to reduce vibration transfers to the driver. Optional double-glazed windows to reduce noise and improve temperature control in extreme ambient conditions. Trustworthy features such as continuously variable speed control and virtual gears implemented for machine control, automatic braking controls to maintain speed on slopes, anti-reverse function, smooth direction changes without shocks on the drivetrain or powertrain, and programmable speed management, which improves operator efficiency and reduces fatigue.
Performance and Productivity
20% increase in capacity compared to previous models, making the R1700 XE a true 15-ton (16.5-ton) loader for loading, transportation, and truck loading applications. Fast dumping times - 13.2 seconds to lift, dump, and lower - combined with a top speed of 18 km/h (11 mph) and a new traction control system, reduce cycle times, move more materials, and decrease cost per ton. Excellent machine balance and a new electrohydraulic braking system that facilitates loading and transportation cycles. Cutting-edge hydraulic system that offers 65% higher lifting force than previous versions and a lifting and tilting capacity of 24,190 kg. Features that ensure high responsiveness, such as the Auto Dig function, which automates bucket loading, and the pilot-controlled steering circuit, which provides more precise maneuvering in tight spaces.
Electric drive system and battery
Proven, designed, integrated, validated, and supported by Caterpillar, the Switched Reluctance (SR) electric drive system is known for its reliability, ease of cooling, and high performance. The battery system is also proven and durable, allowing for fast charging and high efficiency. Caterpillar's cooling system optimizes battery performance and lifespan. Electrical safety is integrated at every level of the battery system, with multiple layers of redundancy and tests that comply with international standards. These industry-leading onboard batteries maximize available operating time and provide an alternative to costly static charging infrastructure, as well as the need for additional batteries, battery handling, and replacement. It can be fully recharged in 30 minutes, or in 20 minutes using two MEC500 Cat mobile equipment chargers.
Mobile equipment charger
The first autonomous mobile equipment charger MEC500 Cat, which can be towed, dragged or transported by a forklift, eliminates the need for expensive static charging infrastructure. Charges quickly, with high output power (300-1,000 volts) and the ability to be used alone or in tandem for optimized charging; increases voltage to adapt to variable input voltages and offers adjustable output current that can be used to regulate charging. Plugs in wherever there is mine power, and two units can charge in parallel with a single transformer. Equipped with multiple safety protocols with ground fault monitoring, constantly regulating and protecting during the charging process. Designed for tough conditions, with protection against rock falls, water and dust resistance, key components mounted against vibrations and seismic activity, and moisture sealing with a closed air conditioning system.
Reliability and durability
Front chassis section with four plates offering a new fully integrated front axle support molding that absorbs impacts, vibrations, and increased displacement loads associated with the machine's larger capacity and higher weight. Increased axle housing thickness for protection against abrasion and resistance to corrosion. Visibly stronger lifting arms, with additional steel thickness, to ensure that extreme loads encountered during loading and trimming are effectively dissipated for a long lifespan. Chassis, powertrain, engine, and components that are built to be rebuilt.
Ease of maintenance
The ECMs are located in a single, air-cooled and sealed housing, located on the machine's service platform. Revised and corrected articulation with simplified hydraulic pathways and more space for interventions and cleaning. Modular components that can be removed and reinstalled as a single unit, greatly speeding up the machine's return to service. Improved access for maintenance operations, with a pivot-opening radiator guard and consolidation of filters and main maintenance tasks in a centralized maintenance section, with oil coolers and batteries located just below. Electric drive system with fewer moving parts and extended maintenance intervals; waterproof electrical connectors that block dust and moisture; and remotely mounted test ports for testing and troubleshooting.
