Positive filtered ventilation with a pressurized cab is standard. Fresh air or re-circulated air can be selected with a switch on the left console.
CAB STRUCTURE AND MOUNTS
The cab shell features a thick steel tubing. This improves resistance to fatigue and vibration. The cab is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing operator comfort.
To maximize visibility, all glass is affixed directly to the cab, eliminating window frames. The upper front windshield opens, closes and stores on the roof above the operator with a one-touch action release system.
A pwoerful engine with excellent reliability and low fuel consumption delivering more while boosting youjr bottom line.
The Cat C7.1 engine has been designed to meet U.S. EPA Tier 2, EU Stage II and China Tier 2 emission regulations. The engine is powerful, strong and durable to meet all of your application needs. An ECO-mode feature helps to reduce fuel consumption by up to 15 percent for fuel-concious customers. The C7.1 engines incorporate porven, robust components and precision manufacturing you can count on for reliable and eeifcinet operation. This is a proven engine that boasts improved reliability, as it’s less sensitive to low quality fuel and also delivers better fuel consumption
AUTOMATIC ENGINE SPEED CONTROL
Automatic engine speed control is activated during no-load or light-load conditions which reduces engine speed to minimize fuel consumption.
Radial seal air filters feature a double-layered filter core for more efficient filtration and is located in a ocmpartment behind the cab. A warning is displayed on the monitor when dust accumulates above a preset level.
The C7.1 engine feautres an improved filtration system to ensure good reliability to fuel injection system components. Intervals have been extended and the number of filters reduced to maximize your profit potential.
Efficient hydraulic system with low effort joysticks provides precise control regardless of your application.
Hydraulic system pressure is 35000 kPa (5,076 psi) with 202 L/min (53.36 gal/min) flow from each of the two hydraulic pumps for increased digging performance and producitivity.
An independent pilot pump enables smooth precise control for the front linkage, swing and travel operations.
The 320D/D L Series 2 hydraulic system and component locations have been designed to provide a high level of system efficiency. The main pumps, control valves and hydraulic tank are located close together to allow for shorter tubes and lines between components, which reduce friction loss and pressure drops.
HYDRAULIC CROSS-SENSING SYSTEM
The hydraulic cross-sensing system utilizes each of to hydraulic pumps to 100 percent of engine power under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns.
AUXILIARY HYDRAULIC VALVE
Control circuits are available as attachments to improve versatility. They allow operaion of high- and medium-pressure tools such as shears, grapples, hammers, pulverizers, multi-processors and vibratory plate compactors.
BOOM AND STICK REGENERATION CIRCUIT
Boom and stick regeneration circuits save energy during boom-down and stick-in operation which increases efficiency, reduces cycle times and pressure loss for higher productivity, lower operating costs, and increased fuel efficiency.
HYDRAULIC CYLINDER SNUBBERS
Snubbers are located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life.
HYDRAULIC ACTIVATION CONTROL LEVER
With the hydraulic activation lever in the natural position all print linkage, swing and travel functions are isolated.
UNDERCARRIAGE AND STRUCTURES
Strong and durable, all you expect from Cat excavators.
CARBODY DESIGN AND TRACK ROLLER FRAMES
The X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units to deliver exceptional strength and service life.
The upper frame is designed using inverse “T” shape beams made out of high-tensile-strength steel providing excellent durability whatever your application. The 320D/D L Series 2 incorporates a one-piece upper frame table which improves strength and reliabiltiy. Both the boom tower and the main frame are constructed of solid plates and the areas adjacent to the boom foot are reinforced, adding to overall durability.
The 320D/D L Series 2 carbody features a box section “X” structure which is designed with the carbody welded close to the ends of the track roller frame. As a result, overall rigidity is high and resistance to torsional rigidity between the track roller frames and the carbody is also high. The standard undercarriage is well suited for applications that require frequent repositioning of the machine, restricted work space, or uneven rocky terrain. The long (L) undercarraige maximizes stability and lift capacity. This long, wide and sturdy undercarriage offers a very stable work platform.
ROLLERS AND IDLERS
Sealed and lubricated track rollers, carrier rollers and idlers provide excellent service life to keep your machine in the field and working longer.
The 320D/D L Series 2 uses a grease-lubricated type track link with grease being sealed between the pin and the bushing. These seals deliver longer wear life by preventing dirt and debris from entering into the space between the pin and the bushing. The master link incorporates a split type pin which helps make routine service and maintenance quick and easy.
Reliable, durable and versatile to meet all your application needs.
Cat front linkages are designed for maximum versality, productivity and high efficiency whatever the application.
HEAVY DUTY FRONT LINKAGE
The 5.7 m (18’8″) heavy duty (HD) reach boom is reinforced to be used in the severest applications abd provide maximum digging capability. They are made of high-tensile-strength steel using a large box-section design with interior baffle plates and an additional bottom guard for long life and durability. The HD reach boom has two stick options available to meet all your application requirements. The 2.9 m (9’6″) heavy duty (HD) stick is most versatile option and very good for for truck loading and trenching applications where you need additional working range. The 2.5 m(8’2″) heavey duty (HD) stick is ideally suited to applications requiring larger bucket sizes. it maximizes digging forces and enables you to get your jobs completed faster.
MASS BOOM FRONT LINKAGE
The mass excavation (ME) front linkage is designed to maximize machine performance through superior digging forces and a larger bucket capacity. The 5.2 m(17’1″) mass excavation boom is reinforced with a geometry designed to maximize machine productivity. It also incorporates a large cross-section and internal baffle plates for long life and durability. the 2.4 m (7’11”) mass excavation stick was designed mainly for large earth moving and is made of high-tensile-strength steel in a box-section to make it strong and durable.
SERVICE AND MAINTENANCE
Simplefied service and maintenance features save you time and money.
The design and layout of the 320D/D L Series 2 was made with the service technician in mind. Most service locations and are easily accessible at ground level to allow service and maintenance to get completed quickly and efficiently.
AIR FILTER COMPARTMENT
The air filter feature a double-element construction for superior cleaning efficiency. When the air filter plugs, a warning is displayed on the cab monitor. Maintenance free batteries are standard along with a battery disconnect switch.
A service on the right side of the upper structure allows ground-level access to the hydraulic pumps, hydraulic filters, engine oil filter, and fuel filters.
The left rear service door allows easy access to the engine radiator, hydraulic oil cooler, air-to-air aftercooler, and AC condenser. A reserve tank and drain cock are attached to the radiator for ground level maintenance.
A concentrated remote greasing block on the boom allows the greasing of hard-to-reach locations. A remote mounted greasing point on the swing bearing allows ease of service.
The engine radiator fan is enclosed by a steel guard that provides maximum protection when carrying out routine service and maintenance.
Anti-skid platting covers the entire upper structure and storage box to prevent slipping during maintenance. Safety is further enhanced with the addition of countersunk bolts to reduce trip hazards.
DIAGNOSTICS AND MONITORING
The 320D/D L Series 2 is equipped with Scheduled Oil Sampling (SOSSM) ports for the hydraulic system, engine oil and coolant. Standard hydraulic test ports enable a service technician to quickly and easily fault find in the event. of service issue.
