Proven Reliability

The Cat C9.3B Engine offers high power density with a combination of proven electronic, fuel, and air circuits. It features an electric fuel priming pump, a water/fuel separator, and a secondary fuel filter. The rigorous component design and machine validation process results in unprecedented reliability and availability.
Long Lifespan

The transmission and extra-robust axles support extreme applications. The automatic powershift transmission with planetary gears (4 forward/4 reverse) is equipped with long-lasting components. The full-flow hydraulic filtration system with an additional filtration loop improves the reliability of the hydraulic circuit and the lifespan of the components. A next-generation equipment pump increases its flow at a lower engine speed and improves hydraulic response.
Superior Energy Efficiency and Productivity

New Autodig components with automatic definition tires for high and uniform bucket filling factors offer up to 10% higher productivity compared to the previous Cat model. The lock-up clutch powershift transmission improves energy efficiency while providing optimal performance. Single clutch and gear change between stops for quick acceleration and speed on slopes. Application profiles allow machine settings to be optimized for different applications at the touch of a button. Work supports allow drivers to improve and optimize their skills. Performance Series buckets use a system approach to balance bucket shape with linkage capabilities, resulting in higher filling factors and better material retention compared to other buckets of the same nominal capacity. The engine idle automatic shutdown system significantly reduces idle time, total hours, and fuel consumption. The standard open/open differential provides more traction when needed. Manual front locks and automatic front and rear locks are available as options. The optional aggregate handling wheel loader configuration offers higher payload for aggregate pile handling.** The deeply integrated engine, powertrain, and hydraulic circuit offer unmatched productivity and energy efficiency. With the Fusion™ quick coupler, the operator can change buckets and components without leaving the cab, speeding up the transition between tasks. **Configurations and optional equipment may vary by region and must comply with Caterpillar's payload policy. Consult your Caterpillar dealer or representative for further information.
Intelligent Machine for Efficient Operation

Cat standard technologies designed to monitor, manage, and improve construction work. - Cat Payload with Assist precisely measures the weight *** of bucket payloads. The data is displayed in real-time to enhance productivity and accurate payload measurement through manual dumping. - Product Link™ wirelessly connects the machine to the office, allowing access to production information and essential health requirements for quick and informed decision-making to better manage your business. - The new Autodig function enables the operator to fully automate bucket loading to improve fill factors and loading time. - Automatic definition tires encourage proper loading techniques, significantly reducing tire slippage and wear. - Built-in work supports and user controls simplify usage. Optional Cat Advanced Payload with Assist: - The automatic tipping assistance function automates final bucket loading to meet planned loading time. - List management, job site integration, and extended scale improvement functions help manage and improve productivity and operational profitability. Optional subscription to the Cat Productivity application provides access to detailed and comprehensive information to help manage and improve productivity and profitability of your operations. ***Not legally suitable for commercial use.
Security Features

The rear camera enhances visibility at the back of the machine to allow you to work safely and confidently. The optional 360° visibility system allows the driver to monitor what is happening around the machine at all times. The optional Cat Detect radar technology raises awareness of the environment by monitoring the work environment and sending alerts to drivers in case of danger. The cabin is accessible through a wide door, an optional remote door opening, and staircase-shaped steps that ensure stability in any situation. The floor-to-ceiling windshield, large mirrors with integrated blind spot mirrors, and rear camera provide excellent panoramic visibility. Computerized monitoring center with multiple warning indicators. The monitored seat belt is provided as standard and can be upgraded with an optional external indicator. Optional access lighting and an access lighting system for maintenance under the hood provide illuminated access to the machine and daily controls, even in the dark.
Work Comfortably in the Brand New Cabin

Seat and suspension easily adjustable for better driver comfort. It is available with three levels of equipment and can be equipped with a 4-point harness (kit). Extra space to increase legroom and adjustable seat controls for optimal driver comfort and performance. The automatic air conditioning system maintains the desired freshness in the cabin. The new dashboard and high-resolution touch screen(s) inside the cabin are easy to use, intuitive, and user-friendly. Soundproofing, seals, and viscous cabin mounts reduce noise and vibrations to provide a quieter working environment. The manual measuring unit steering wheel offers easy and precise machine steering. Optionally available, the electrohydraulic joystick steering system mounted on the seat provides very high precision and reduces driver fatigue, for maximum comfort and precision. The new generation anti-roll control functions as a damper, allowing for a smoother ride for the driver on difficult terrains.

Specially Designed Configurations

Specific versions for each application directly from the factory for optimized performance and longer lifespan in the most challenging applications, including: - The Industrial and Waste Sector models include the necessary protections and reinforcements for work in transfer stations, recycling depots, landfills, and demolition sites. - The Forestry model increases lifting and digging capacities for good performance and high productivity in log and chip processing work in paper or pellet mills and sawmills.
