Automatic Central Hydraulic Systems for Front Loaders 700568

Controlling the cost of excavating and moving a yard of earth is the greatest challenge confronting the earthmoving industry today. This industry, in particular, faces both a shortage of skilled operators and an inflationary wage environment. To increase a skilled operator's efficiency and decrease learning time for new operators, the Tyrone Automatic Central Hydraulic System automatically directs the proper amount of hydraulic power at the proper time to the various functions of the front loader. Hydraulic valving coordinates pump flows for approximately constant lock-to-lock times throughout the cycle regardless of engine rpm and at the same time, controls the interaction of the lift cylinder, bucket cylinder, and transmission disconnect for the fastest possible full bucket loading in both stockpile and virgin bank.
