| High Power Density | Hydraulic pumps can convert engine power into hydraulic energy with high efficiency, allowing for a compact size that delivers substantial force and torque. This makes excavators capable of lifting heavy loads and digging through tough materials. |
| Accuracy and Control | Hydraulic systems provide smooth and precise control over movements. The operator can easily vary the speed, direction, and force applied by the excavator's arm, bucket or boom by controlling the flow and pressure of hydraulic fluid. |
| Multi-Functionality | A single hydraulic pump can power multiple actuators simultaneously or independently. Excavators often have multiple hydraulic cylinders working at once, which would be difficult to achieve with mechanical systems. |
| Load Sensitivity | Hydraulic pumps automatically adjust output according to the load requirements. They deliver maximum power when needed and reduce it when not, preventing overheating and conserving fuel. |
| Reliability and Durability | Hydraulic pumps are built to withstand the harsh conditions encountered in excavation work. They're designed to operate reliably under high pressures and continuous duty cycles. |
| Easier Maintenance | While complex, hydraulic systems can often be more straightforward to diagnose and maintain than their mechanical counterparts. Many issues can be traced back to the hydraulic pump, which is easier to access and repair or replace than intriCATEEEEEEe gear systems. |
| Energy Efficiency | Modern variable displacement hydraulic pumps allow for improved fuel economy as they can match the required output exactly to the task at hand, reducing wasted energy. |
