Abstract: A vibration management system (20) for a machine (10) may receive a signal indicative of an amount of vibration experienced via one or more sensors or an amount of vibration to be expected based on data from a surveying system (26) which may be combination with data from a positioning system (28) and a speed monitoring system (27). The vibration management system (20) may add this data to a vibration history of a machine member 11 to predict the accumulative vibration the machine member 11 may be exposed to. This characteristic is compared to a desired characteristic and an adjusting action may be taken in response to a deviation as to have a second predicted characteristic approach the desired characteristic. A site management system (500) may use the deviation to allocate resources.

Abstract: A hydraulic pressure transformer has a port block which is attached to an end cap. The end cap includes a plurality of ports opening at an end face and at least one actuation port opening at or near a peripheral surface. A barrel which is rotatable about an axis includes a second end face and a plurality of cylinders having respective cylinder ports which open at the second end face. A port block disposed between the first end face and the second end face is rotatable about an axis and has a first face surface, a second face surface and a plurality of ports extending between the first face surface and the second face surface. The port block includes a radial periphery and at least one vane extending radially outward from the radial periphery to a position adjacent the peripheral surface of the opening.

Abstract: A hydraulic pressure transformer for the conversion of an input hydraulic power to an output hydraulic power, and particularly suitable for use in a work machine having a hydraulic work unit requiring a hydraulic input power, has a port block with improved balanced loading which is attached to an end cap in a simplified manner. The end cap includes an opening having a peripheral surface and a first end face. The end cap further includes a plurality of ports opening at the end face and at least one actuation port opening at or near the peripheral surface. A barrel which is rotatable about an axis includes a second end face and a plurality of cylinders having respective cylinder ports which open at the second end face. A port block is disposed within the end cap opening between the first end face of the end cap and the second end face of the barrel.

Abstract: A hydraulic pressure transformer for the conversion of an input hydraulic power to an output hydraulic power includes a housing with a generally planar face surface and a plurality of ports opening at the face surface. A barrel which is rotatable about an axis includes a generally spherical end face and a plurality of cylinders opening at the end face. A port block interposed between the barrel and the housing is rotatable about the axis. The port block has a first face surface, a second face surface and a plurality of ports extending between the first face surface and the second face surface. The ports selectively fluidly interconnect the plurality of cylinders in the barrel with the plurality of ports in the housing. The first face surface is generally spherical and abuts the end face of the barrel. The second face surface is generally planar and abuts the face surface of the housing.
