Benefits & Features

Cat® C7.1 ACERT™ Engine

The Cat C7.1 ACERT engine delivers more horsepower using less fuel than the previous series engine.

Emissions Solution

The C7.1 ACERT engine is equipped to meet U.S. Tier 4 Interim emission standards. Driven by customer input, Caterpillar’s aftertreatment regeneration solution ensures the machine works 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 System

The 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 System

The cooling system features side-by-side-mounted hydraulic oil cooler and engine radiator with a tilt-out condenser and air-to-air aftercooler for easy cleaning. The fan automatically adjusts to ambient temperatures to help reduce fuel consumption and noise.

Speed and Power Control

The 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.

Seats

The seat range includes air suspension, heated, and air cooled options. Each option includes a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments to meet operator needs for comfort and productivity.

Controls

The 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 the 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.

Monitor

The 324E is equipped with a new LCD (Liquid Crystal Display) monitor that’s 40% bigger and has higher resolution than the previous model’s monitor. 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.

MP3-Ready Radio and Power Supply

The standard radio is equipped with a new auxiliary audio port for MP3 players. Two 12-volt power supply sockets are located near key storage areas for charging electronic devices.

Storage

Storage spaces are located in the front, rear, and side consoles. 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 Control

The climate control system features five air outlets with positive filtered ventilation, which makes working in the heat and cold much more pleasant for operators.

Hydraulic Horsepower

Hydraulic 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 Valves

The 324E uses a high-pressure system to tackle the toughest of work in short order. The machine features a simple, highly efficient 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.

Return Filter

The return filter is a capsule-type design with a cartridge inside. The Cat cartridge features a handle to help remove and change oil without spillage or contamination. A sensor attached to the filter warns the operator if it is full or exceeds a certain pressure level.

Swing Priority Circuit

The swing priority circuit on the 324E 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.

Electric Boom Regeneration Valve

An electric boom regeneration valve minimizes pump flow when the boom lowers down, which helps improve fuel efficiency. This unique Cat feature is optimized for any dial speed setting being used by the operator, which results in less pressure loss for higher controllability and more productivity with lower operating costs.

Stick Regeneration Circuit

The 324E regenerates the flow of oil from the rod end to the head end of the stick cylinder during low-load, stick-in operation – an approach that saves energy and expense.

Frame

The upper frame (1) includes new reinforced mountings to support the Roll-Over Protective Structure (ROPS) cab; the lower frame is reinforced to increase component durability.

Undercarriage

Fixed long 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 two-piece guiding guard is now offered to help maintain track alignment and improve performance in multiple applications. A redesigned motor housing prevents mud packing and debris buildup around seals.

Counterweights

Two counterweights (3) are available: 4.0 mt (4.4 t) and 6.75 mt (7.4 t) options. The counterweight removal system comes with new integrated links that enable easy removal for maintenance or shipping.

Booms and Sticks

The 324E 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.

Selections

There are three basic boom options: HD, SLR, and ME. Sticks match the boom descriptions and applications below:

An extensive range of Cat Work Tools for the 324E includes buckets, hydraulic hammers, multi-processors, scrap and demolition shears, grapples, rippers, and thumbs. Each is designed to optimize machine versatility and performance.

Couplers

Quick 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.

Cat Center-Lock™ Pin Grabber Coupler

Center-Lock is the pin grabber style of coupler and features a patent-pending locking system. A highly visible secondary lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool.

Buckets

Cat Next Generation buckets are designed as an integral part of the 324E 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.

Four Durability Categories Suitable for Any Situation

Caterpillar 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.

Specialty Buckets

In addition to the four levels of bucket durability categories, several specialty buckets are available for the 324E, each with a different purpose:
  • Ditch cleaning for cleaning ditches, slope grading, and other finish work
  • Center-Lock Pin Grabber Performance for maximum digging performance while keeping the versatility and convenience of a coupler
  • Power for use in abrasive applications where breakout force and cycle times are critical
  • Wide tip for low-impact material where leaving a smoother floor and minimal spillage are necessary

Hydraulic Kits

Caterpillar offers field-installed hydraulic kits that are uniquely designed to integrate Cat Work Tools with Cat excavators. Hoses and tubes are pre-made, pre-shaped, and pre-painted to make installation quick and easy.

Comprehensive Product Support

All Cat Work Tools are backed up by a world-wide network of well-stocked parts depots and highly experienced service and support personnel.

Cat® Grade Control Depth and Slope

This optional system combines traditional machine control and guidance with standard factory-installed and calibrated components, making the system 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 Link*

This 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.  *Product Link licensing not available in all areas.

Steps on the track frame and storage box along with extended hand and guard rails (2) to the upper deck enable operators to more securely work on the machine.

Time Delay Cab and Boom Lights

For a predetermined amount of time after the engine start key has been turned to the “OFF” position, lights will be illuminated to enhance visibility. The time delay can vary from 0 to 90 seconds, which can be set through the monitor.

High Intensity Discharge (HID) Lights

Cab lights operate on a time delay for enhanced safety; lights can be upgraded to HID for greater night time visibility.

Visibility – Windows

Increased glass coverage enhances visibility while meeting the latest ROPS regulations.  The 70/30 split configuration features an upper window equipped with handles on the top and both sides so the operator can easily slide it to store in the ceiling. The lower window is removable and can be stored on the left wall of the cab shell.  The large skylight provides enhanced overhead visibility, excellent natural lighting, and good ventilation. The skylight can be opened completely to become an emergency exit.

Monitor Warning System

The monitor is equipped with a buzzer that can warn operators of critical events like “Engine Oil Pressure Decrease,” “Coolant Temperature High,” or “Hydraulic Oil Temperature High” so they can take any necessary action.

Rearview Camera

An optional rearview camera (3) housed in the counterweight area is available as an attachment. The image projects through the cab monitor to give the operator a clear picture of what’s behind the machine.
