Hydraulics

Outstanding Performance
With two percent more hydraulic pressure for additional lift, swing torque and breakout forces, the 315D L hydraulic system is designed for high efficiency and performance. Auxiliary hydraulic and electrical lines are routed to the boom foot making installation of hydraulic circuits much easier. The new compact design utilizes shorter tubes and lines, reducing friction and pressure drops, resulting in a more efficient use of power.
  • Hydraulic snubbers at the rod end of the boom cylinders and both ends of the stick cylinders cushion shock, reduce sound and increase cylinder life.
  • Flow is reduced to a minimum when controls are in neutral to reduce fuel consumption and extend component life.
  • Electronic Under Speed Control electronically adjusts pump output to not exceed engine power preventing the need to reserve engine power to avoid engine stalls.
  • Hydraulic Cross-Sensing System uses two hydraulic pumps to 100 percent of engine power under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.

Boom and Stick Regeneration Circuit
The boom and stick regeneration circuit saves energy during boom-down and stick-in operation, increasing efficiency and lowering operating cost.
