Benefits & Features
Operator Station
Easy Access
Conveniently located grab irons and large steps mounted to the undercarriage allow easy access in and out of the cab.
Quiet Cab
The cab is resiliently mounted. Sound suppression panels reduce outside noise levels to a very low level.
Comfortable Seat
The suspension seat adjusts to weight and offers excellent lumbar support, adjustable height armrests and numerous seat adjustment.
Visibility
Wide, large windows help assure excellent visibility in all directions, which is especially critical when roading the machine or working on public roadways.
Ventilation
Strategically located vents circulate forced air, heat or defrost air for maximum comfort.
Controls
The control panel switches are conveniently located. Warning lights are clearly displayed on the upper portion of the control panel.
Electronic Control System
Hydraulic System
Closed center, variable flow, load-sensing hydraulic system.
Swing Pump
A separate dedicated variable displacement piston pump and fixed displacement piston motor power the swing mechanism.
Efficient and Expandable
Up to three optional hydraulic valves can be added to the main valve stack for additional hydraulic functions.
Control Panel
The right side console contains switches for the power mode selector, automatic engine control, lights, windshield wiper and washer and travel speed selector.
Integrated Electronic System
A microprocessor monitors and controls M320 parameters and functions.
Functions
Three power mode settings.
Automatic Engine Speed Control
When activated, this device reduces engine speed to a minimum during periods of inactivity which reduces noise and saves fuel.
Electronic Engine Speed Control
When activated, this device reduces engine speed to a minimum during periods of inactivity which reduces noise and saves fuel.
Protective Measures
Maximum engine power is reduced when engine temperature is too high or hydraulic oil temperature is too low or too high.
Travel Speed Lock (option)
Holds the travel pedal in the maximum position to ease the strain on the operator. Pedal is released when brake is activated.
Engine
Rating
Conservative 104.4 kW/139 hp rating, high displacement to power ratio of 3.66 and low rpm operation ensure long life and exceptional reliability.
Direct-Injection
Direct-injection fuel system with adjustment-free pumps, provides efficient, accurate fuel metering. High injection pressures mean added fuel savings.
Cycle Design
Four-stroke-cycle design uses long power strokes for more complete fuel combustion and efficiency.
Long-Life Design
Long-life design includes large bearing surfaces, alloy steel valves, lightweight cam roller followers and easily replaceable crankshaft seals.
Torque Rise
The engine is designed for high torque rise at middle rpm which is suited for excavator applications.
Service
The engine is longitudinally mounted on the right for easy ground access for service/maintenance of the oil filter, oil filler, oil drain valve, fuel filter, V-belt tightener and dipstick.
Valve Cover
Valve cover and oil pan noise barriers, for maximum engine noise and emission reduction.
Undercarriage
Undercarriage
Strong and durable welded frame structure built with large sections and thinner plates for maximum stiffness.
Dozer Blade
A very useful addition for leveling and back-filling or clean-up work.
Outriggers
Indicated for maximum operation stability when digging and lifting.
Axles
Heavy duty axles.
Booms, Sticks
One-Piece Boom
One-piece boom 5.65 meters (18 ft. 6 in.) for all standard applications.
Hydraulically Adjustable Boom
Hydraulically Adjustable Boom maximum 5.41 meters (17 ft 9 in) for improved visibility and machine roading balance.
Material Handling Boom
Material Handling Arrangement Boom 6.8 m (22 ft 4 in), stick 4.9 m (16 ft 1 in)
Finite Element Analysis
With FEA, a more stable and reliable base frame and upper frame structure could be designed.
Sticks
Four sticks are available for maximum flexibility.
Bucket Linkage
Two bucket linkages are offered. One with diverter valve, the other without.
Hydraulics
Expandable Hydraulic System
The flow distances between hydraulic components are minimized. This guarantees minimum efficiency related hydraulic power losses.
XT-Hose and Couplings
Caterpillar XT hoses and couplings meet the critical flexibility and strength demands of the M320.
Hammer Lines
Hammer Lines (optional) - Factory installed hammer hydraulic lines are available.
High Pressure Hydraulic Lines
High Pressure Hydraulic Lines (optional) - Factory inst
Medium Pressure Hydraulic Lines
Medium Pressure Hydraulic Lines (optional) - Factory installed medium pressure lines are available.
Buckets and Tips
Optional Buckets
A complete range of Cat specifically designed general purpose and extreme service backhoe buckets are avilable for maximum flexibility. All are available either with or without adjuster groups.
Data not available.
