摘要:
Devices and methods for air-assisted loading of soil in an earth-moving apparatus (10) are disclosed. One aspect of a device includes a source of a current of air (54) and at least one conduit for directing the current of air towards soil moved by the earth-moving apparatus (10). The apparatus (10) includes a frame (12) having opposing sides (24, 26), supported by at least two ground-engaging wheels (22), and a bucket (16) having a floor and a pair of upstanding sidewalls. A cutting blade (14) may be attached to the bucket or disposed between the opposing sides of the frame. An air supply system (54) for delivering a current of air to soil moved by the earth-moving apparatus (10) is also included. Methods for loading soil into an earth-moving apparatus (10) are also disclosed.
摘要:
The present invention includes hydraulic systems designed to allow the selection of a source of pressurized hydraulic fluid to lift a load. In one embodiment, a hydraulic system in accordance with the present invention comprises a hydraulic accumulator that may be selected as a source of pressurized hydraulic fluid to lift a load. Such a hydraulic system may or may not be part of a cushion ride system. The present invention also includes methods for selecting a source of pressurized hydraulic fluid to lift a load and earth moving or ground leveling apparatus that allow the selection of a source of pressurized hydraulic fluid to lift a load.
