Benefits & Features
Operator Station
Excellent Viewing Area
Excellent viewing area through large, wide windows. A large push-open skylight provides upward visibility. The upper front windshield features a pillar mounted wiper to provide unobstructed front viewing.
Greater Control Convenience
Each of the controls is positioned within easy reach of the operator.
The Double Wall, Pressed Cab Shell
The double wall, pressed cab shell is mounted to the swing frame using viscous mounts for reduced sound and vibrations.
Caterpillar Electronic Control System Panel
The Caterpillar Electronic Control System panel includes fuel level, hydraulic oil temperature and engine coolant temperature gauges, machine condition indicators and operator controls in a single console for ease of use.
Ventilation System
At the touch of a switch, the operator can choose between fresh or recirculated air, or (optional) air conditioning.
Joysticks
Joysticks control all implements and swing functions with minimal effort. The integrated joystick consoles adjust to operator preference. Joystick consoles are suspended as part of the seat arrangement.
Dial Throttle
Dial throttle with ten settings for simple, precise engine speed adjustment.
Hand or Foot Actuated Travel Controls
Hand or foot actuated travel controls allow the operator to move the excavator while working the front-end. Hand levers are easily removable.
Hydraulic Activation Control Lever
Hydraulic activation control lever deactivates hydraulic functions and prevents start-up when the operator exits the cab.
Suspension Seat
The fully adjustable standard suspension seat includes an impressive range of comfort features. It has fore/aft height and weight adjustments and a retractable seat belt.
Serviceability
Ground Level Service Points
More ground level service points for fuel-water separator, battery, radiator fluid level, window washer fluid level and pilot system filter.
Filter and Filter Locations
Improved filters and filter locations make maintenance easier.
Design and Layout Improvements
Design and layout improvements translate to ease of use.
Water Separator
Water separator removes water from fuel even when under pressure and is located in the pump compartment.
Remote Greasing Block
Remote greasing block on the boom and two grease points for the swing bearing deliver grease to hard to reach locations.
Electronic Power Unit Control
Electronic Power Unit Control has diagnostic capabilities for Cat dealer use.
Electronic Control System
Electronic Power Unit Control System
The Electronic Power Unit Control System controls state-of-the-art hydraulics and engine performance for maximized productivity, increased fuel efficiency and lower emission and sound levels.
Automatic Engine Speed Control
Automatic Engine Speed Control reduces engine speed to 1300 rpm during light-load or no-load applications. A button on the right control lever engages the low idle function, reducing engine speed to 1100 rpm. Pressing the button again returns the machine to the previous setting.
Electronic Engine Underspeed Control
The Electronic Engine Underspeed Control balances engine and hydraulic output for maximum performance and fuel efficiency.
Operator Control Panel
The operator control panel allows optimization of performance in all applications.
Machine Monitoring System
The Machine Monitoring System uses a progression of indicators, action lamps, and alarms to inform the operator of machine conditions.
Service Mode
The Service Mode of the Electronic Power Unit Control delivers fast, detailed diagnosis of machine conditions, improving uptime.
Hydraulics
Responsiveness
Excellent responsiveness aid operation and improves cycle time.
Hydraulic Relief Pressure
High hydraulic relief pressure increases stick and bucket forces for better productivity and maximum lift capacity.
Hydraulic Cross-sensing System
The hydraulic cross-sensing system improves productivity with fast implement speeds and quicker, stronger pivot turns.
Boom Regeneration Circuit
Boom regeneration circuit diverts oil to lower the boom. Pumps have all pressure and flow available for other circuits.
Stick Regeneration Circuit
Stick regeneration circuit diverts oil to assist stick-in operation. Flow from the pumps can be directed to other circuits, saving energy.
Pump Flow
Pump flow decreases when controls are in neutral for reduced fuel consumption and sound.
Auxiliary Hydraulic Valve
Auxiliary hydraulic valve is standard on the 318B L for use with optional hydraulic circuits.
Hydraulic Cylinder Snubbers
Hydraulic cylinder snubbers at rod-end of boom cylinders and both ends of stick cylinders cushion shocks, reduce sound and increase cylinder life.
Cat XT Hose
Cat XT hose meets the critical flexibility and strength demands of the 318B L.
Cat 3046T Engine
Automatic Engine Control
Three-stage control maximizes fuel efficiency and reduces sound levels.
Turbocharged
The Cat 3046 engine is turbocharged to increase engine power by burning fuel with greater efficiency.
Crankshaft
Eight balance, one-piece, forged crankshaft enhances balance and decreases vibration and is induction hardened to improve abrasion resistance.
Pistons
Heat resistant aluminum alloy pistons have a short compression height, reducing weight and improving efficiency.
Connecting Rods
Forged, high carbon steel connecting rods with a smaller connecting rod to crank radius ratio result in a lightweight, powerful, compact engine.
Undercarriage
Precision Robotic Welding
Precision robotic welding helps ensure quality welds. These welds increase rigidity, reduce internal stresses and enhance durability for the chassis and track roller frames.
Chassis
Heavy-duty, X-shaped chassis are designed for durability.
Track Links
Strutted track links are sealed for longer life. Track rollers, carrier rollers and idlers are also sealed and lubricated for excellent service life.
Travel Motors
Smooth, auto-shifting two-speed travel motors offer high travel speeds and unmatched pull on slopes or turns.
Long (L) Undercarriage
The long (L) undercarriage has a 7'3" (2210 mm) gauge that maximizes lift capacity over the front and over the side.
Elimination of Ledge
The elimination of the ledge at carbody and roller frame juncture reduces material build-up and makes digging out easier.
Standard Guards
Standard idler guards and center section track guiding guards maintain track alignment and provide additional protection on side slopes.
Optional Sections
Optional front and rear sections can be ordered to provide full-length protection.
Booms and Sticks
Choice of Three Sticks
The choice of three sticks plus a wide selection of buckets and attachments means the 318B L offers several combinations of reach and digging forces for optimum versatility.
Variety of work tools
Choose from a variety of work tools such as hammers, compactors, grapples or crushers. Ask your Cat dealer for information on attachments or special configurations.
Structures
Carbody Design
Advanced carbody design stands up in the toughest applications.
Track Roller Frames
Robot-welded track roller frames are press-formed, pentagonal units that deliver exceptional strength and service life.
Rugged Main Frame
Rugged main frame is designed for maximum durability and efficient use of materials.
