The ergonomically designed operator station is spacious, quiet, and comfortable, assuring high productivity during a long work day. All switches are located on the right-hand console for convenient access.
The monitor is a full-color Liquid Crystal Display (LCD) that can be adjusted to minimize sun glare and has the capability of displaying information in 27 languages.
Low-effort pilot-operated joystick controls are designed to match the operator’s natural wrist and arm position for maximum comfort and minimum fatigue.
The standard suspension seat provides a variety of adjustments to suit the operator’s size and weight including fore/aft height and weight. Wide adjustable armrests and a seat belt are also included.
The consoles feature a simple functional design to reduce operator fatigue, ease of switch operation, and excellent visibility. Both consoles have attached armrests with tilting adjustments.
The cab shell features thick steel tubing along the bottom perimeter of the cab, improving resistance to fatigue and vibration.
The cab shell 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.
Pillar-mounted wipers increase the operator’s viewing area and offer continuous and intermittent modes.
The Cat 3054CA engine has been designed to meet U.S. EPA Tier 2 and EU Stage II emission regulations. This engine incorporates a time-proven mechanical governor and a low-pressure fuel injection system that are major contributors to the improvement of fuel system robustness, high fuel efficiency, and ease of troubleshooting. High filtration performance from the primary filter incorporating a water separator and a secondary filter also help to improve fuel filtration system reliability.
Automatic Engine Control and Fuel Delivery
With a net power of 82 kW (110 hp) the 318D L Series 2 has been designed with fuel economy in mind and burns approximately 3% less fuel when compared with the larger 318D L depending on application.
Available as a standard feature, economy mode allows you to balance the demands of performance and fuel economy while maintaining the breakout forces and lift capacity enjoyed at standard power.
The 318D L Series 2 hydraulic system is designed for high efficiency and performance. The new compact design utilizes shorter tubes and lines to reduce friction and pressure drops, resulting in a more efficient use of power.
- Hydraulic snubbers at the rod end of the boom cylinders and both ends of the stick cylinders cushion shock, reduce sound, and increase cylinder life.
- A hydraulic cross-sensing system uses two hydraulic pumps under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.
Boom and Stick Regeneration Circuit
The boom and stick regeneration circuit saves energy during boom-down and stick-in operation, increasing efficiency and lowering operating cost.
Operators do not need to learn different modes. An automatic boom and swing priority function automatically selects the best mode based on joystick movement.
Caterpillar uses advanced engineering and software to analyze all structures, creating a durable, reliable machine for robust applications. More than 70 percent of the structural welds are robotic and achieve additional penetration over manual welds. These structural components and undercarriage are the backbone of the machine’s durability.
X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press‑formed, pentagonal units that deliver exceptional strength and service life. Integral to the track roller frame are the standard idler and center guards, which help maintain track alignment when traveling or working on slopes.
Grease Lubricated Track
Grease lubricated track seals protect the track link and deliver long track link pin and bushing inner wear life.
Travel motors with automatic speed selection let the 318D L Series 2 automatically change up and down from high and low speeds in a smooth, controlled manner.
Built for performance and long service life, Cat booms and sticks are welded, box-section structures with thick multi-plate high-strength steel fabrications.
Heavy Duty Stick*
A 2.6 m (8'6") heavy-duty stick has additional plates, new forged parts, and welded joints for increased durability, and digging force. *Offering varies for different regions.
A 2.6 m (8'6") and a 2.9 m (9'6") reach stick maximizes the digging envelope. It is made of high-tensile-strength steel using a large box-section design with interior baffle plates for increased durability. *Offering varies for different regions.
Heavy Duty Boom
The 5.1 m (16'9") heavy-duty reach boom is reinforced making it more durable and recommended for use in severe applications.
The 5.1 m (16'9") reach boom features parts made from a new forging pattern and additional, thicker plates. A light attached to the left side offers improved visibility in dark and low‑light conditions.
An extensive range of Cat work tools for the 318D L Series 2 includes buckets, compactors, grapples, multi-processors, rippers, crushers, pulverizers, hammers and shears. Each is designed to optimize the versatility and performance of your machine.
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.
CW Dedicated Coupler
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.
Center-Lock™ Pin Grabber Coupler*
Center-Lock is the pin grabber style 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. *Offering varies for different regions.
Cat Buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine ensuring optimal performance and fuel consumption.
General Duty Buckets (GD)
These buckets are designed for digging in low-impact, moderately abrasive materials such as dirt, loam, gravel and clay.
Heavy Duty Buckets (HD)
HD buckets are a good starting point when application conditions vary. Especially when conditions include mixed dirt, clay and sand and gravel.
Severe Duty Buckets (SD)
These buckets are best suited to highly abrasive applications such as shot rock, sand stone and granite.
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 spare parts depots and highly experienced after-sales service and support personnel. Work tools available vary by region. Contact your local Cat dealer for more information about the work tools available in your region.
Fast, Efficient Service with Extended Intervals
Most service points are at the ground level for easy access with extended intervals to increase machine availability.
A service door on the right side of the upper structure allows ground-level access to the pump, pilot filter, drain filter, and the engine oil filter.
The left service door allows easy access to the engine radiator, oil cooler, air-to-air-aftercooler, water separator and first and second fuel filter. A reserve tank and drain cock are attached to the radiator for simplified maintenance. The air filter features a double-element construction for superior cleaning efficiency. When the air cleaner plugs, a warning is displayed on the monitor screen inside the cab.
The hydraulic return filter is an in-tank design with a service life of 2,000 hours. A sensor indicates through the in-cab monitor when the filter is plugged and needs to be replaced.
The engine radiator fan is enclosed by fine wire mesh, reducing the risk of an accident.
Anti-skid plate covers top of storage box and upper structure to prevent slipping during maintenance.
Diagnostics and Monitoring
The 318D L Series 2 is equipped with S·O·SSM sampling ports and hydraulic test ports for the hydraulic system, engine oil, and for coolant. A test connection for the Cat Electronic Technician (Cat ET) service tool is located behind the cab.
