Overview

Demolition Excavator with the Largest Attachments for 6 to 7 Story Work

Demolition work has never been easier than with the Cat® 340 UHD Excavator. Reach higher with larger attachment capabilities to maximize performance. Enjoy the versatility, precision, and efficiency offered by standard Cat technologies. Combined with a stability monitoring system and an Operator Protective Guards (OPG) cab, the 340 UHD keeps you working longer and safer.

Benefits

Maximize Performance

Hydraulic quick disconnect requires no tools to swap booms in 15-20 minutes. Standard Cat Payload, Cat 2D E-fence, and Cat Grade with 2D technologies provide additional versatility, precision, and efficiency.

Reliable High Reach

Experience the industry’s highest level of performance with more stick pin height and larger attachment capabilities. Reach up to 22 m (72'2") or 25 m (82'0") with a UHD boom, or choose between three stick options for the retrofit boom.

Comfort and Safety

Stay comfortable all day long in a deluxe cab with OPG protection. Tilt cab up to 30 degrees for better tool visbility while the 254 mm (10 in) touchscreen monitor indicates easy to read stability monitoring system.

Latest Features

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.

Cat Payload and Advanced Payload*     
        
  • 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™** to analyze jobsites and individual assets for remote management of production targets and key metrics.

*Payload technologies are not legal for trade.
**VisionLink subscription required.

High Performance with Low Fuel Consumption

High Performance with Low Fuel Consumption

        
  • High fuel efficiency ensures more work per unit of fuel.
  •     
  • The C9.3B engine and electrohydraulic system will power through all different types of material.
  •     
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments, including the largest attachments needed for demolition work.
  •     
  • Achieve higher vertical reach up to 22 m (72'2") or 25 m (82'0") with a UHD boom.
  •     
  • Match the excavator to the job with three power modes – Smart, Power, and Eco. Smart mode automatically matches engine and hydraulic power to digging conditions, providing maximum power when needed and reducing power when it isn't to help save fuel. Power mode is maximum power all the time. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.
  •     
  • The high-efficiency hydraulic fan cools the engine on demand to help reduce fuel consumption; standard reverse function makes it easy to keep cores clean.
Boost Efficiency and Productivity

Boost Efficiency and Productivity

        
  • 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. 
  •     
  • VisionLink™ provides actionable data insights for all assets – regardless of fleet size or equipment manufacturer.* Review equipment data from your desktop or mobile device to maximize uptime and optimize assets. Equipment management features provide up-to-date asset tracking of your entire fleet. You can track asset location, operating hours, fuel level, health issues, and overall utilization. Monitor equipment health with fault codes, fluid analysis, and inspection due dates. It's all about making informed, data-based decisions to help reduce operating costs. Productivity management features enable you to analyze overall job site performance. You'll be able to track tonnage moved, production targets, and payload, as well as Grade 3D and compaction data. These vital metrics help you to reduce costs and improve jobsite operational efficiency.
  •     
  • Remote Flash is a mobile application that allows you to update onboard software without a technician being present, allowing you to initiate software updates when convenient, increasing your overall operating efficiency.
  •     
  • Cat Payload onboard weighing helps you achieve precise load targets to improve your operating efficiency with a retrofit boom. Pick up a load of material – with either a bucket or grapple – and get a real-time weight estimate without even swinging.
  •     
  • Combine Payload with VisionLink™ and remotely manage your production targets. The monitor’s USB port lets you download results from one shift all the way up to 30 days of work, so you can manage your progress without needing an internet connection or VisionLink subscription.
  •     
  • Standard Cat Grade with 2D with a retrofit boom indicates depth and slope on the monitor with auditory alerts.
  •     
  • The stability monitoring system continuously informs operators of work tool position within the safe working range and warns when approaching the stability limit.
  •     
  • Know the excavator’s exact position relative to GPS and GLONASS systems. The machine automatically compensates for excavator pitch and roll caused by sloping ground conditions.

*Data field availability can vary by equipment manufacturer.
Reliable in Tough Conditions

Reliable in Tough Conditions

        
  • Reinforced booms, sticks, and frame make the machine more durable and built to last.
  •     
  • Standard high-ambient temperature capability is 52°C (125°F) with cold start capability at -18°C (0°F).
  •     
  • Auto hydraulic oil warmup gets you to work faster in cold temperatures and helps prolong the life of components.
  •     
  • Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
  •     
  • The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.
Simple to Operate

Simple to Operate

        
  • Start the engine with a push button; use a Bluetooth® key fob or the unique Operator ID function.
  •     
  • Program each joystick button, including power mode, response, and pattern, using Operator ID; the machine will remember what you set each time you go to work.
  •     
  • Make moving the excavator much easier with standard Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
  •     
  • Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.
Work in Comfort

Work in Comfort

        
  • Get in and out of the cab easily with the standard tilt-up left console.
  •     
  • Deluxe cab with premium seat offers a heated and ventilated seat for year-round comfort.
  •     
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  •     
  • Stow your gear with plenty of in-cab storage beneath and behind the seat and in the consoles.
  •     
  • Use the standard radio’s USB ports and Bluetooth® technology to connect personal devices and make hands-free calls.
