Electrohydraulics steadies cargo removal on ships

Feb. 22, 2012
Eaton's F(x) electrohydraulic controller was chosen by New Zealand cargo handling company Page Macrae Engineering to improve reliability of its grab system.

Eaton Corp.'s Hydraulics Group, Eden Prairie, Minn. announced Monday that Page Macrae Engineering of Mount Maunganui, New Zealand, a major manufacturer of ship cargo handling equipment in Australasia, has selected Eaton components to help improve reliability, as well operation and safety, of the grab-control system of its Diesel Hydraulic Series grabs.

Operated via remote control by a ship’s crane operator, the grabs discharge bulk material from a ship’s hold with the aid of an Eaton F(x) electrohydraulic system featuring a mobile control valve, piston pump, controller, screw-in cartridge valves, hose and fittings, and filtration products.

This is just one of many recent news stories about this technology being used in New Zealand. Last year, a mining company chose the Eaton F(x) technology to control its rock crushers. The technology is also used in many other mobile applications where high power density in a compact package is required.

Eaton was chosen for a number of reasons, the company said, notably for the fact that its integrated control/hydraulic system package can facilitate a two-stage, bucket-opening process that reduces losses in windy conditions and enables the engine to slide out quickly for maintenance and repairs.
