The 580N EP is powered by Parker Hannifinâs P330 single-section gear pump that delivers 28.5 gpm of hydraulic flow at pressures to 3,350 psi for multiple work and auxiliary functions.
Depending on equipment, the hydraulic system holds up to 28 gal of oil, with roughly half of that in the reservoir. The loader’s two lift cylinders have a bore or 3.25 in, stroke of 30.2 in., and a piston rod diameter of 1.75 in. Its two dump cylinders have a bore and stroke of 3.00 in., 9.18 in., respectively, and also a 1.75-in. rod.
The backhoe has a 4.50-in. bore 38.25-in. stroke boom cylinder with a 2.25-in. diameter piston rod. Its dipperstick (elbow joint) cylinder is has a 4.25-in. bore, 24.74-in. stroke, and also a 2.25-in. rod. The bucket cylinder has a 3.25-in bore, 35.35-in. stroke, and, again, a 2.25-in. rod. The backhoe’s two swing cylinders are 3.75-in. bore, 11.50-in. stroke, and 2.00-in. rod.
Benefits of Hydraulics
The 580N EP offers several benefits over the competition and its previous counterparts. It comes standard with ProControl, a swing-dampening system that eliminates rebound on the backhoe, providing faster cycle times, less wear on components, greater operator precision, and less operator fatigue.
Power Lift allows contractors to increase hydraulic capacities of the boom and bucket forces. This provides as much as 8% lifting more lifting power from a smaller, more fuel-efficient machine. It also reduces engine speed for greater control of the load being lifted.
Another production-boosting feature is the industry’s only fully integrated hydraulic quick coupler. This feature proves valuable for users who regularly change buckets or attachments because they save time and effort by being able to change implements without leaving the cab.
The 580N EP offers added convenience because operators can quickly and easily attach any of several external tools to its auxiliary hydraulic system. This eliminates the need for transporting air compressors, generators, and other heavy equipment to a job site.
A popular option is Case’s Extendahoe feature, which adds even more versatility to the 580N EP. Extendahoe uses 3.00-in. bore cylinder in the dipperstick to extend the length of the dipperstick more than 40 in. In normal operation, the 580N EP can work in tight spaces. But when additional reach is needed, the Extendahoe cylinder can be activated for up to 42.05 in. of additional reach. Doing so allows more work to get done without moving the machine. It also provides access to sites where the backhoe can’t get as close to the work area due to regulations or obstacles.
