Machine Setup Simplification

    
• At the touch of fingertips and navigating user-friendly icons, the latest operator oriented User Interface (UI) maximizes uptime and gets crews to work without delay. From re-ordering work tool lists to creating new work tool combinations as needed, operators can quickly set up machines and easily access information.
    
• The interface allows operators to maintain accuracy and makes the most of every second of their shift. Adding the ability to input couplers and attachments into the system makes setting up work tool combinations highly efficient by significantly reducing calibration time. It also eliminates the need to measure up again when changing Cat© work tool attachments and makes it manageable for a single person to check and adjust for bucket wear.

    
• The Cat Grade 3D Ready option includes all the hardware required for the Grade with 3D system, installed and tested from the factory. This option provides an easier upgrade path for customers who want to add Grade with 3D after their initial purchase. To activate, contact your Cat Dealer to purchase the required 3D software licenses. Licenses can be installed remotely or manually loaded onto the machine.

    
• Cat Payload provides operators with on-the-go weighing to help them hit load targets and avoid overloading, underloading, or misloading materials. Advanced Payload is a system upgrade that offers expanded features and capabilities, including custom tags, daily totals, and electronic ticketing. Combine Payload with VisionLink® Productivity* to analyze jobsites and individual assets for remote management of production targets and key metrics.

Performance Powerhouse

    
• Work up to 3000 m (9,840 ft) above sea level without de-rating.
    
• The exclusive hydrostatic swing circuit has a dedicated bi-directional swing pump, swing motors, charge pump, and charge accumulator. The swing pump supplies oil to the swing motor; the charge pump and charge accumulator prevent cavitation (air bubbles) and overheating. The circuit enables regenerating swing brake energy and independent management of cylinder oil flow, resulting in higher efficiency and smoother, more predictable performance when you multitask with the excavator.
    
• Powerful swing torque easily handles changes in momentum, uneven terrain, and consistent high-impact connections, helping operators make their work swift and precise.
    
• Did you know baffle plates help increase an excavator’s strength-to-weight ratio? That is why Caterpillar incorporates the plates in high-stress areas like the boom, stick, and frame. Reinforcing the machine without adding significantly more weight also helps provide years of reliable performance, even in the harshest environments.
    
• The cylinder rods are reinforced with additional wear rings to help reduce oil leaks. The car body has thick baffle plates for a long service life. The thick track link has large bolt joints to help maintain bolt retention. Track rollers have a large shaft diameter to help prevent bending and oil leaks while increasing the 374’s loading capacity, which means more reliable production for you.
    
• Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
    
• The center track guiding guard helps align the excavator track when traveling and working on slopes.
    
• The sloped track frame prevents mud and debris accumulation, helping reduce the risk of track damage.
    
• Auxiliary hydraulic options allow you to use a wide range of Cat® attachments.
    
• Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.
    
• Match the excavator to the job with three operating modes: Power, Smart, and ECO.
    
• Smart mode automatically adjusts power for the highest fuel efficiency – less power for tasks such as swinging and more power for digging.
    
• Enhanced heavy lift mode increases system pressure to help you easily pick and place heavy material.
    
• Auto warm-up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
    
• Don’t let the temperature stop you from working. This excavator has a high-ambient capability of 52° C (125° F) and a standard cold start capability of –18° C (-0.4° F).
    
• The Cat® C15 engine meets Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA. 

Exceptional Efficiency Through Technology

    
• The latest operator oriented User Interface (UI) has been designed to maximize uptime by allowing operators to easily reorder work tool lists and quickly create new work tool combinations. It also eliminates the need to measure up again when changing Cat® work tool attachments and makes it manageable for a single person to check and adjust for bucket wear.
    
• Cat® Lift Assist helps avoid machine tipping. With visual and auditory alerts, operators will know if their load is within the excavator’s safe working range limits.
    
• Cat® 2D E-Fence restricts the front linkage from moving beyond operator-defined preset boundaries for the ceiling, floor, wall, swing, and cab.  It helps operators avoid jobsite hazards such as traffic, keeps personnel safe, and helps you save on costly repairs, equipment downtime, and potential jobsite fines.
    
• Cat® Detect - People Detection for excavators is an intelligent vision camera system that can alert an operator when someone enters a machine’s hazard zone.*
    
• Cat® Grade with Assist helps operators stay on grade simply and effortlessly with semi-autonomous digging. It automates boom, stick, and bucket movements to deliver more accurate cuts with less effort.
    
• Cat® Grade with 2D for excavators is an indicate system that helps operators reach grade faster.* Select your target depth and slope and watch the Grade with 2D system use on-board processors and sensors to provide real-time guidance on the distance to grade.
    
• Cat® Grade with 3D for excavators helps operators grade more quickly, accurately, and efficiently, improving productivity.* It incorporates GNSS technology and RTK positioning guidance to streamline the grading process for complex designs commonly encountered on large infrastructure and commercial projects. This system allows operators to work confidently, eliminating guesswork while cutting and filling to precise specifications.
    
• The Cat® Grade 3D Ready option includes all the hardware required for the Grade with 3D system, installed and tested from the factory. Activation requires the purchase of additional 3D software licenses, contact your Cat Dealer for details.
    
• Upgrade to our dual antenna GNSS for maximum grading efficiency. The system lets you create and edit designs on the touchscreen monitor while you’re on the job, or you can have the plan design sent to the excavator to make your work easier. Plus, you get added benefits of avoidance zones, cut and fill mapping, lane guidance, and augmented reality along with advanced positioning capability.
    
• All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica. Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.
    
• Cat® Payload provides operators with on-the-go weighing to help them hit load targets and avoid overloading, underloading, or misloading materials. Advanced Payload is a system upgrade that offers expanded features and capabilities, including custom tags, daily totals, and electronic ticketing. Combine Payload with VisionLink® Productivity**  to analyze jobsites and individual assets for remote management of production targets and key metrics.
    
• Cat® Operator Coaching allows operators of all experience levels to take their efficiency and productivity to the next level. With tips and data at their fingertips, operators can track and improve their productivity through everyday work on the job site. Gain data-based insights towards operators and operations when you pair Operator Coaching with VisionLink® Productivity.** There are two coaching tip categories –     
          
  1. Operational Efficiency Tips: Help operators stay at the top of their game by identifying areas to increase skill and efficiency, such as digging technique and idle times.
          
  2. Machine Health Tips: Some actions are inefficient and cause unnecessary wear and tear on the machine and its components. Following Machine Health Tips can help extend the life of the machine, improve digging technique, and reduce fuel waste.
