Automatic Engine Speed Control reduces engine speed during light-load or no-load applications.
Electronic Engine Underspeed Control
Electronic Engine Underspeed Control balances engine and hydraulic output for maximum performance and fuel efficiency.
Operator Control Panel
Operator control panel allows optimization of performance in all applications.
Monitoring System
Machine monitoring system uses a progression of indicators, action lamps, and alarms to inform the operator of machine conditions.
Service Mode
Service Mode of the Electronic Power Unit Control delivers fast, detailed diagnosis of machine conditions improving uptime.
Hydraulics
Control Responsiveness
Dramatically increased control responsiveness aids operation and improves cycle time.
Hydraulic Cross-Sensing System
Hydraulic cross-sensing system improves productivity with faster implement speeds and quicker, stronger pivot turns.
Boom Regeneration Circuit
Boom regeneration circuit diverts oil to lower the boom.
Fine Swing Control
The optional fine swing control cushions swing start and stop for better implement control.
Pump Flow
Pump flow decreases when controls are in neutral for reduced fuel consumption and sound.
Scheduled Oil Sampling valve
Scheduled Oil Sampling valve allows faster sampling and maintenance time, speeding machines back to production.
Auxiliary Hydraulic Valve
Auxiliary hydraulic valve is standard on the 320B 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.
Caterpillar XT Hose
Cat's XT hose meets the critical flexibility and strength demands of the 320B L.
Hydraulic Tank
The hydraulic tank is located closer to pumps for increased hydraulic efficiency through decreased line loss.
Engine
Automatic Engine Control
Automatic Engine Control with convenient one-touch command.
Direct Unit Injection
Efficient, direct unit injection fuel system means lower operating costs.
Turbo-charged
Turbo-charged 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.
Aluminum Alloy
