PCLS Hydraulics
Pressure-compensated, load sensing (PCLS) hydraulics, provide better multifunctioning, smoother machine control, and up to 15 percent greater craning capacity with Lift Mode, collectively providing a distinctive customer experience and unmatched machine reliability. PCLS are highly valuable for Underground customers due to its productivity, lift capacity, quality and reliability. The machine delivers all the advantages of PCLS hydraulics in the 14-foot digging-depth category, enabling operator efficiency and productivity through improved multifunction control. For additional performance, the 310SL HL has up to 5-percent-more rear-craning capacity and 10 more net horsepower.
- The variable displacement axial piston pump creates hydraulic flow on demand, increasing hydraulic efficiency, decreasing fuel consumption, and lowering the daily operating cost for your customer.
- Selective flow auxiliary rate selection has been moved into the monitor, eliminating the need to get out of the cab and adjust a manual knob on all PCLS machines.
- Buttons for the horn, selective flow, auxiliary proportional roller, and extendable dipperstick have been incorporated into the pilot controls.
- The 310SL HL uses the proven hydraulic architecture of the 410L, including the same hydraulic pump and valves.
- The 310SL utilizes the same rear valve as the 310SL HL and 410L, for improved swing metering and return-to-trench accuracy
- The PCLS system enables excellent multifunctioning ability at all engine speeds.
- Faster cycle times improving trenching productivity by 16 percent over the prior design.
- Trenching operation can be conducted at a lower engine rpm, reducing fuel consumption and jobsite noise.
- Precision mode reduces hydraulic flow by 55 percent, allowing accurate, detailed backhoe work to be performed without sacrificing overall hydraulic-lift performance.
