A new piston accumulator that provides exceptional levels of safety for the steering systems of wheel loaders and similar vehicles has been introduced by parker. The accumulator stores energy from the vehicle`s hydraulic system, providing reserve of energy, which enables the machine to be brought safely to a halt in the event of engine failure with its consequent loss of drive to the hydraulics. The new accumulator system ensures operator and vehicle safety and at the same time, speeds and simplifies installation by saving space, reducing pipe work, connections and assembly work, and simplifying the order process. The system is based on a standard parker acp series piston accumulator. It incorporated a solenoid valve and check valve into a specially extended cap with side mounted fluid port. Extensive field tests have demonstrated how energy stored in the accumulator enables a wheel loader to be steered, under control but without power, through a predetermined series of maneuvers and brought to a halt in a controlled manner. Hydro-pneumatic accumulator technology supplies a range of proven benefits for manufacturers and operators of construction vehicles. In addition to steering system accumulators, parker`s piston accumulators are widely used in braking and ride control systems to increase productivity and to improve operator comfort and safety. The new accumulator was designed using parker`s in-house-developed accumulator modeling technology.Hannifin manufacturers pistons, bladders and diaphragms, accumulators and accessories-covering the full spectrum of mobile and industrial applications.
