This configuration uses SPCL directional control valves, which eliminate additional load sense and load holding check valves.
This directional control circuit has a multiple load sense configuration.Ī bridge circuit provides complete control of lift and lower functions for excavators with low flow requirements. HydraForce SPCL16-40 valves control up to 152 lpm (40 gpm) while holding loads with extremely low leakage. HydraForce cartridge valves and manifolds, especially the vibration-resistant HyPerformance™ valves, are perfect for use on excavators because they can be designed to fit a machine's tight clearance requirements and attach to a specific mounting bracket.Īre filled with opportunity for elegant electrohydraulic control of the bucket, boom, cab, stabilizers, swing or slew motor, and steering. The operator must be able to use the excavator for accurate work when not transporting a load.Įxcavators therefore need a completely customized control solution, which often has to be flanged directly on the boom cylinder(s) and take up as little space as possible When excavating, there should be no drift of the boom when the suspension is switched off. The Unique Requirements for an Excavator Boom SuspensionĮxcavators transport loads but they also perform work from a stationary position. In this system, an electrohydraulic proportional TS valve is used to provide load-sensing relief of the EV directional element. Optimally sized custom boom suspension manifoldĪrm and Boom Suspension For Excavators Pressure Spike SolutionĪn EP valve can be used to reduce the overshoot spike in a closed center load-sensing system by popping open momentarily, allowing the hydraulic pump time to de-stroke when needed.Ī proportional relief valve system can be a great relief for the excavator operator experiencing an overload. When de-energized a network of check valves and tuned orifices are used to regulate accumulator pressure. This on-off solution, when energized, uses a piloted directional element combined with a damping accumulator to smooth out the bounce on the bucket, effectively keeping more of your load in your bucket during transport. This basic suspension circuit for a wheeled excavator, working in parallel to the main directional control valve, can be incorporated to damp the effects of rugged terrain on your load.
