Fast and responsive Cat hydraulics deliver the power and control needed to keep material moving at high volume.

Caterpillar Hydraulics

Technologically advanced hydraulic system enables the 5230B to respond to operator controls with fast, predictable, smooth operation. Cat integrated hydraulic system draws maximum engine power for precise, full-powered hydraulic response and top productivity.

System Optimization

Fast Cycle Times

Efficient closed-center hydraulic system delivers quick lift and swing performance and control regardless of boom, stick or travel demand.

Cat PPPC System

The exclusive Cat Proportional Priority Pressure Compensating (PPPC) hydraulic system responds to multiple circuit demands for smooth, efficient operation and controllability. Automatic flow proportioning divides required flow to each function according to demand for precise, multitasking operation. Implements (boom, stick and bucket) work at a constant speed regardless of load and engine speed. When flow is required by more than one function at a time, PPPC valves deliver required flow to each function to maximize hydraulic efficiency.

Electronically Controlled Pumps

Cat designed electronic pump controller utilizes a microprocessor to regulate and match hydraulic output to engine power for maximum power efficiency. Pump controls prevent excessive engine lugging for optimum fuel efficiency.

Swing System

Two dedicated variable-displacement piston pumps power the swing function for quick, full-powered swing performance regardless of load. Intelligent, independent, open-center load sensing system delivers needed swing flow separate of boom, bucket or travel demand for high speed cycling performance while minimizing flow and power requirements.

Hydraulic System Protection

Advanced filtration system uses 10-micron reverse-flow hydraulic fluid filters in return and case drain lines, and 200-micron high-pressure screens in pump discharge lines for clean hydraulic operation and longer component life. Diagnostic system continually monitors screens and filters for restrictions.
