Overview
Smooth operation, reliable performance and convenient serviceability and maintenance. The 313B CR incorporates a significantly reduced tailswing radius and a curved upper structure for production in tighter quarters. In addition, the boom raises to a higher angle to reduce the front swing radius.

Benefits & Features
Operator Station
Quiet Operator Station
Quiet operator station has ergonomic control placement, convenient adjustments, low lever and pedal effort, sliding door and efficient ventilation.
Adjustable Seat
The adjustable low-back seat with seat belt provides increased comfort.
Greater Convenience
Greater control convenience. Each of the controls is positioned within easy reach of the operator.
Joysticks
Joysticks control all implements and swing functions with minimal effort. The integrated joystick consoles adjust to operator preference.
Travel Controls
Hand actuated travel controls are ergonomically designed and allow the operator to move the excavator while working the front-end.
Manual Shift Pedal
Manual shift pedal for switching between high and low travel speeds. High speed is maintained only when the operator's foot is on the pedal.
Sliding Door
Sliding door allows easier operator and entry and exit when working in tight areas or against walls on job sites.
Cab Shell
The double wall, pressed cab shell is mounted to the swing frame using silicon oil-filled rubber viscous mounts for reduced sound and vibration.
Ventilation System
The operator can choose between heating or (optional) air conditioning.
Skylight
Polycarbonate skylight and removable sunshade provide upward visibility.
Rear View Mirror
Rear view mirror, mounted at the rear of the machine, contributes to safe, efficient operations.
Standard Attachments
Ashtray, coat hook, drink holder and storage compartment are all standard.
Adjustable Right Console
Right console is independently adjustable and contains the dial-type accelerator, key switch, instrument panel and console slide lever.
Adjustable Left Console
Left console is independently adjustable and includes the light switch, electrical priming pump switch, work mode selector, power mode selector and hydraulic activation control lever.
Hydraulics
Component Layout
Hydraulic system component layout on the 313B CR is designed for maximum efficiency.
Cross-Sensing System
Hydraulic cross-sensing system improves productivity with faster implement speeds and quicker, stronger pivot turns.
Boom Priority Work Mode
Boom priority work mode provides flow priority during boom-up operations - ideal for deep trenching, bank forming or truck loading applications.
Activation Lever Control
Hydraulic activation lever control cuts pilot pressure to machine functions when in the "locked" position. This safety feature prevents the machine from operating unless the operator is in the cab.
Boom Regeneration Circuit
Boom regeneration circuit diverts oil to lower the boom. Pump pressure and flow are 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.
Cylinder Snubbers
Hydraulic cylinder snubbers at rod-end of boom cylinders and both ends of stick cylinders cushion shocks, reduce sound, increase cylinder life and prevent loads from falling when in compact swing positions.
Electronic Snubber
An electronic snubber at the head-end of the boom cylinder reduces pilot pressure and allows for variation in the damping region.
Auxiliary Hydraulic Valve
Auxiliary hydraulic valve is standard on the 313B CR for use with optional hydraulic circuits.
Engine and Peripherals
Technologies & Materials
Leading-edge technologies and materials of the MMC 4D34-TE1 engine deliver low fuel consumption, enhanced engine performance and lower operating costs.
Engine Key Switch
The engine key switch has four positions: "Off", "On", "Heat" and "Start".
Radiator Fan
Inclined, flow-type radiator fan achieves excellent cooling and low sound levels.
Undercarriage, Track, & Blade
Advanced Carbody Design
Advanced carbody design and pressed pentagonal, box-shaped, cross section track frame result in increased rigidity.
Closed-Floating Seals
Track rollers, carrier rollers and idlers use closed-floating seals and are lubricated for excellent service life.
Rubber Segmented Track
Optional rubber segmented track is available for use in urban construction to prevent damage to asphalt roadways and to reduce sound and vibration.
Optional Blade
Optional blade increases versatility and helps level a working space so the 313B CR sits firmly and digs vertically.
Addition Of Rubber Track
Additional holes in the standard 500mm (20") track shoes allow for the additional of rubber track pads.
Maintenance & Serviceability
Gull Wing Type Doors
Gull wing type service doors on both sides of the machine provide easy service access.
Faster Maintenance
Faster maintenance means improved uptime and a better value.
Ground Level Service
More ground level service points.
Water Separator
Water separator with primary filter removes water from fuel even when under pressure.
Greasing Block
Remote greasing block on the boom and two grease points for the swing bearing deliver grease to hard-to-reach locations.
Steps and Handrails
Angled steps and a large handrail on the right side of the machine allow for easy access to the upper structure for checking the engine oil level and changing the fuel filter.
