Reduced emissions, economical and reliable performance
Cat® C7.1 ACERT™ EngineThe Cat C7.1 ACERT engine delivers more horsepower using less fuel than the previous series engine.
Emissions SolutionThe C7.1 ACERT engine is equipped to meet Stage IIIB emission standards. Driven by customer input, Caterpillar’s aftertreatment regeneration solution ensures the machine works as normal with no operator intervention needed. The machine comes with two modes of regeneration: automatic and manual. In automatic mode, the machine starts the regeneration process once the filtering system reaches a certain level and conditions are optimal. The system will not interrupt the work process and can regenerate during machine operation. Manual mode enables the operator to override the automatic mode. With a touch of a button inside the cab, this mode allows the operator to move the machine from flammable or heat-restricted areas before initiating the regeneration process.
Biodiesel-Ready Fuel SystemThe C7.1 ACERT engine is equipped with an electronic-controlled high-pressure fuel system that includes an electric priming pump and three-layer fuel hose to allow the use of biodiesel (meeting ASTM 6751 or EN 14214) up to B20 (biodiesel 20% mixture).
Cooling SystemThe cooling system features side-by-side and tilt-out radiators, oil cooler and air coolers for easy cleaning and a fan that automatically adjusts to ambient temperatures to help reduce fuel consumption and noise.
Speed and Power ControlThe E Series features speed control to maintain a constant speed - regardless of load - to improve fuel economy. Three different power modes are offered: high power, standard power, and economy power. The operator can easily change between modes through the monitor or console switch to meet the needs for the job at hand - all to help manage and conserve fuel.
Comfort and convenience to keep people productive
SeatsThe seat range includes air suspension, heated, and air cooled options. All seats include a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments to meet operator needs for comfort and productivity.
ControlsThe right and left joystick consoles can be adjusted to meet individual preferences, improving operator comfort and productivity during the course of a day. With the touch of a button, one-touch idle reduces engine speed to help save fuel; touch it again or move the joystick and the machine returns to normal operating level. The heavy lift mode increases machine system pressure to improve lift - a nice benefit in certain situations. Heavy lift mode also reduces engine speed and pump flow in order to improve controllability.
MonitorThe 329E is equipped with a 7" LCD (Liquid Crystal Display) monitor that’s 40% bigger than the previous model’s with higher resolution for better visibility. In addition to an improved keypad and added functionality, it’s programmable to provide information in a choice of 42 languages to support today’s diverse workforce. An “Engine Shutdown Setting” accessible through the monitor allows owners and operators to specify how long the machine should idle before shutting down the engine, which can save significant amounts of fuel. The image of the rearview camera is displayed directly on the monitor. Up to two different camera images can be displayed on the screen at the same time.
Power SupplyTwo 12-volt power supply sockets are located near key storage areas for charging electronic devices.
StorageStorage spaces are located in the front, rear, and side consoles. A specific space near the auxiliary power supply holds MP3 players and cell phones. The drink holder accommodates large mugs with handles, and a shelf behind the seat stores large lunch or toolboxes.
Automatic Climate ControlThe climate control system features five air outlets with positive filtered ventilation, which makes working in the heat and cold much more pleasant.
Power to move more dirt, rock, and debris with speed and precision
Hydraulic HorsepowerHydraulic horsepower is the actual machine power available to do work through implements and work tools. It’s much more than just the engine power under the hood - it’s a core strength that differentiates Cat machines from other brands.
Main Control Valve and Auxiliary ValvesThe 329E uses a high-pressure system to tackle the toughest of work in short order. The machine features a highly efficient and simple back-to-back main control valve to improve fuel consumption and reliability. Also, shortened spool lengths and a built-in drift reduction valve have been added for greater controllability.
Swing Priority CircuitThe swing priority circuit on the 329E uses an electric valve that’s operated by the machine’s Electronic Control Module (ECM). Compared to using a hydraulic valve, an electric valve allows for more finely tuned control, which is critical during material loading.
SmartBoom reduces stress and vibrations transmitted to the machine and provides a more comfortable environment. It is particularly well suited for the following applications:
- Rock scraping. SmartBoom simplifies the task and allows the operator to concentrate on stick and bucket, while the boom freely goes up and down without using pump flow.
- Hammer work. The front parts automatically follow the hammer while penetrating the rock. Blank shots or excessive force on the hammer are avoided, resulting in longer life for the hammer and the machine.
Electric Boom Regeneration ValveThis valve minimizes pump flow when the boom lowers, which helps improve fuel efficiency. It is optimized for any dial speed setting being used by the operator and results in less pressure loss for higher controllability, more productivity, and lower operating costs.
Structures & Undercarriage
Built to work in rugged environments
FrameThe upper frame (1) includes reinforced mountings to support the Roll-Over Protective Structure (ROPS) cab; the lower frame is reinforced to increase component durability.
UndercarriageFixed gauge long and long narrow undercarriage systems are available to support various work applications. Heavy-duty track rollers, precision-forged carrier rollers (2), press-fit pin master joints, and enhanced track shoe bolts improve durability and reduce the risk of machine downtime and the need and cost to replace components. A segmented three-piece guiding guard is now offered to help maintain track alignment and improve performance in multiple applications.
CounterweightsThe standard counterweight (3) weighs 5.8 mt. Super Long Reach (SLR) configurations come with a heavier 6.75 mt counterweight. Integrated links enable easy removal of the counterweight for maintenance or shipping.
Made for high stress and long service life
Booms and SticksThe 329E is offered with a range of booms and sticks (see list below). Each is built with internal baffle plates for added durability, and each undergoes ultrasound inspection to ensure weld quality and reliability. Large box-section structures with thick, multi-plate fabrications, castings, and forgings are used in high-stress areas such as the boom nose, boom foot, boom cylinder, and stick foot to improve durability. The boom nose pin retention method is a durable captured flag design. Boom durability is improved with a number of plate thickness changes. Also, the front linkage pins’ inner bearing surfaces are welded, and a self-lubricated bearing is used to extend service intervals and increase uptime.
SelectionsThere are four basic boom options: HD, ES, SLR, and ME. Sticks match the boom descriptions and applications below:
Dig, hammer, rip, and cut with confidenceAn extensive range of Cat Work Tools for the 329E includes buckets, hydraulic hammers, multi-processors, scrap and demolition shears, grapples, and rippers. Each is designed to optimize machine versatility and performance.
CW Quick CouplersQuick couplers allow one person to change work tools in seconds for maximum performance and flexibility on a job site. One machine can move rapidly from task to task, and a fleet of similarly equipped machines can share a common work tool inventory. The CW quick coupler can pick up any work tool and is equipped with a wedge-style locking system that fits the quick coupler tight to the tool hinges. Due to the tapered wedge design, there won’t be any play during its entire life. Also, it is interchangeable with different machine classes. The CW is highly suitable for harsh applications such as demolition and quarries.
BucketsCat buckets are designed as an integral part of the 329E system and feature new geometry for better performance. The leading edge has been pushed forward, resulting in more efficient filling and better operator control for greatly improved productivity. Wear coverage in the corners and side cutter and sidebar protector coverage are improved; a new lift eye design accepts a wide range of shackle sizes. All benefits are captured in a new bucket line with a new bucket naming convention. Following are the types offered:
Four Durability Categories Suitable for Any SituationCaterpillar offers four standard bucket categories for excavators. Each category is based on intended bucket durability when used in recommended applications and material. Each bucket durability type is available as pin-on or can be used with a Quick Coupler. Red areas on bucket images illustrate additional protection against wear as it increases across each category.
Special BucketsSpecial buckets are available for the 329E on request.

Solutions that make work easier and more efficient
Cat® Grade Control Depth and SlopeThis optional system combines traditional machine control and guidance with standard machine components at the factory. With factory-installed and calibrated components, the system is ready to go to work the moment it leaves the factory. The system utilizes internal front linkage sensors - well protected from the harsh working environment - to give operators real-time bucket tip position information through the cab monitor (1), which minimizes the need and cost for traditional grade checking and improves job site safety. It also helps the operator complete jobs in fewer cycles, which means less fuel use. Cat dealers can upgrade the system to full three-dimensional control by adding proven Cat AccuGrade™ positioning technologies, including GPS and Universal Total Station (UTS).
Cat Product LinkThis deeply integrated machine monitoring system (2 and 3) is designed to help customers improve their overall fleet management effectiveness. Events and diagnostic codes as well as hours, fuel consumption, idle time, machine location, and other detailed information are transmitted to a secure web based application called VisionLink™, which uses powerful tools to communicate to users and dealers.
Fast, easy and safe access built in
Service DoorsWide service doors (1) and a one-piece hood design (2) provide easy access to the engine and cooling compartments. Both doors and hood feature enhanced hardware and a new screen design to help minimize debris entry.
CompartmentsThe radiator, pump, and air cleaner (3) compartments provide easy access to major components. The fresh air filter (4) is located on the side of the cab to make it easy to reach and replace as needed.
Other ServicesThe water separator with water level sensor has a primary fuel filter element located in the pump compartment near ground level; the electric priming pump is mounted on the primary filter base and is easy to service compared to traditional hand-priming pumps. The fuel tank features a remote drain cock located in the pump compartment to make it easy to remove water and sediment during maintenance. The engine oil check gauge and oil filter are situated in front of the engine compartment for easy access, and a uniquely designed drain cock helps prevent spills.
