Features

SAFETY

• Large window openings to offer excellent visibility in all directions.
• Safer access and egress with anti-skid upper deck surfaces and 3-point access to cab and machine.
• Four corner oil-cooled braking system that provides excellent control, with service brake system actuated by hydraulic pressure and parking brake function that is spring applied and hydraulic released to ensure braking in the event of loss of hydraulic failure.
• Operator Present System, which protects the machine and operator from uncontrolled machine movements, with hydraulic system neutralization and door sensor.
• Safer service with service area located on cold side of engine, bucket control group safety pins, articulation lock and hinged belly guards.

OPERATOR COMFORT & CONTROL

• Optional enclosed design provides fresh, pressurized, temperature-controlled air circulation with air conditioning.
• Optional sound-suppressed ROPS cab for a quiet, secure working environment.
• Controls, levers, switches and gauges positioned to maximize productivity and minimize fatigue.
• Low-effort, pilot-operated joystick implement control with simultaneous lift and tilt functions to optimize operating efficiency.
• Four corner oil-cooled braking system, which provides excellent control.

PRODUCTIVITY & PERFORMANCE

• Loadrite Payload Control System, which gives the operator accurate, real-time updates on payload weights to help them reach maximum bucket capacities while reducing overloading.
• Increased operator efficiency and optimized performance thanks to electronic auto shift transmission that allows operator to choose between manual or auto shift modes.
• Transmission neutralizer that makes it possible for the operator to engage the service brakes and neutralize the transmission, maintaining high engine rpm for full hydraulic flow, enhancing digging and loading functions.
• Fast cycle times thanks to optional ride control system, which gives operators confidence to travel at speeds above 5 km/h (3 mph) during load and carry operations.
• Productivity-boosting hydraulic system, which delivers exceptional digging and lifting forces for fast cycle times, plus high hydraulic flow rates that provide fast response and powerful lift forces.

POWER & EFFICIENCY

• Cat C15 ACERT engine, which provides unequalled lugging force while digging, tramming and traversing steep grades.
• Torque rise that effectively matches transmission shift points for maximum efficiency and fast cycle times.
• Torque Converter Lockup Clutch that combines maximum rimpull while in torque converter drive with the efficiency and performance of direct drive when the lockup clutch is engaged.
• Mechanically Actuated, Electronic Unit Injection (MEUI™) high-pressure, direct injection fuel system, which electronically monitors operator demands and sensor inputs to optimize engine performance and fuel combustion.
• Cat four-speed planetary power shift transmission matched with the Cat C15 diesel engine to deliver constant power over a wide range of operating speeds.

BUCKETS AND G.E.T.

• Four dump bucket sizes that deliver unmatched productivity and structural reliability, featuring two types of cast corners to help strengthen the side plate to bucket lip joint and allow for various cutting edges.
• Three types of Ground Engaging Tools (GET) available: modular weld-on, which deliver welded part reliability; Bolt-On-Half-Arrow (BOHA), which offer more wear material and feature a bolt-on design that enables fast and easy removal and replacement; and the Durilock Lip Shroud system, featuring hammerless installation and maintenance-free retention of GET, with three interchangeable shroud styles.
• Cat Bucket Pro App, which provides real-time data on GET performance to help you plan maintenance, manage inventory and know cost-per-ton.

RELIABILITY & DURABILITY

• Frame engineered to withstand extreme forces generated during loading and tramming cycles, with deep penetration and consistent welds throughout to ensure structures are solidly fused to provide sturdy platform for the linkage and the axles.
• Proven planetary power shift transmission built for long life between overhauls.
• Spread hitch design that widens the distance between upper and lower hitch plates to distribute forces and increase bearing life.
• Field-proven Cat high pressure XT hydraulic hoses that are exceptionally strong and flexible for maximum system reliability and long life in the most demanding conditions.
• Frame, powertrain, engine and components that are built to be rebuilt, delivering second and third lives.

SERVICEABILITY

• Easy access to daily service points to simplify servicing and reduce time spent on regular maintenance procedures.
• Ground-level access to all tanks, filters, lubrication points and compartment drains, with engine oil and fuel filters installed on cold side of engine, plus fluid-level sight gauges.
• Radial seal air filters that are easy to change, reducing time required for air filter maintenance.
• Sealed, colleted pins fitted to all major bucket and lift arm hinge points for longer pin and bushing life, which reduces maintenance costs and extends service intervals.
• Electrical connectors that are sealed to lock out dust and moisture, harnesses that are covered for protection, and wires that are color- and number-coded for easy diagnosis and repair.

TECHNOLOGY

• Cat Electronic Monitoring System (EMS) that provides continuous access to critical machine data to keep the machine performing at a high level.
• Cat Electronic Technician (ET), which enables quick electronic diagnosis of machine performance and key diagnostic data for effective maintenance and repairs.
• VIMS (Vital Information Management System) GEN3, which combines Health Information Monitoring and VIMS capability in one ECM to monitor vital machine health functions; logs data to help identify areas for improvement in repair planning, operator training, site planning, machine health and personnel performance.
• Factory-ready for remote operation and can be equipped with the industry-proven Cat® MineStar™ Command for underground autonomous solution and machine health monitoring offerings.

SUSTAINABILITY

• Optional EU Stage III and U.S. EPA Tier 3 compliant engine available.
• Optional Ventilation Reduction (VR) Package, which incorporates selective engine hardware and software to reduce diesel particulate matter in the engine exhaust and deliver a significant ventilation rate reduction, a decrease in fuel consumption, and maintained or improved product performance.
• Cat Diesel Particulate Filter, which complements the VR engine by further reducing particulate matter in the exhaust.
• Ongoing research and development into engine compatibility with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels, plus power options like electrification.
• Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions, plus retrofits and upgrades for older machines to incorporate efficiency improvements and emission reductions.
