  • Patent number: 10204388
    Abstract: A method of construction project management is disclosed. In one embodiment, parameters of a construction project design are provided to an asset at a construction site. Geospatial information is then collected by the asset while the asset is implementing parameters of the construction project design at the construction site. The geospatial information is provided to a construction management computing system in real-time. The construction management computing system is remote from the asset. Progress on the construction site design is then dynamically updated in real-time by the construction management computing system based on the geospatial information to create a real-time, as constructed model of the construction project.

  • Patent number: 7222882
    Abstract: A loader implement includes a support mast that is provided with a mounting area for a front loader arrangement. The loader implement includes a roll-over protective assembly that is coupled to one of the other or both of the loader implement, or support mast. The protective assembly can be selectively pivoted between a raised protective position wherein it extends over an operator's platform and a lowered non-protective position, wherein it extends forward of the operator's platform. So as to prevent the loader arrangement from being used without the benefit of the protective assembly in its protective position, the mounting area for the loader arrangement is blocked by the protective assembly when the latter is in its non-protective position and is not cleared to permit the mounting of the loader arrangement until the protective assembly is moved to its protective position.

  • Patent number: 7219452
    Abstract: A trench wheel has a relatively thicker wheel center and gradually tapering side walls that produce a thinner wheel as distance from the hub increases. The wheel center is preferably fabricated from stamped metal into a hat or thimble shape, and has a skirt or brim attached thereto which assists with the retention of an elastomeric outer wheel to the wheel center. Special adapter plates are illustrated which, in combination with the wheel center, permits mounting to both front and rear axles of all popular all-terrain vehicles. A method of controlling water in a field using the trench wheels on a vehicle includes cultivating, planting, and traversing the field to displace earthen matter and thereby channel the field.

  • Patent number: 7204047
    Abstract: A compact excavator includes an upper rotating body mounted rotatably on a lower traveling body, an engine arranged on a rear section of the upper rotating body in a state where a drive shaft thereof is oriented in a horizontal direction, an hydraulic pump connected to the drive shaft, and a sound attenuating plate disposed on a front side of the engine across a width of the excavator. A longitudinal discontinuity is provided in a neighborhood of the pump so as to bring the sound attenuating barrier in a backward displaced state, a blocking portion for a longitudinal discontinuity in the sound attenuating barrier is provided with through holes, pipes extending from the pump, and communicating with a hydraulic device arranged on an outer periphery side of the upper rotating body on the opposite side of the pump are laterally inserted through the through holes.

  • Patent number: 7168191
    Abstract: A hydraulic excavator is equipped with one or more downsizing scheme including at least one of: (i) a bubble removing device for removing bubbles in hydraulic fluid, (ii) a hydraulic tank including a main tank and a variable capacity tank arranged separately from each other, and (iii) a variable capacity tank or hydraulic tank which is fitted to the rear surface of the upper cover of the seat-side block. Thus, the lateral section of the seat can be ultimately downsized to provide a large space around the seat. Then, unlike the prior art, a canopy or a cab of a larger hydraulic excavator can be securely arranged on the upper swing body of a small hydraulic excavator. Since such large parts can be commonly used with large hydraulic excavators, it is possible to significantly reduce the cost of the hydraulic excavator.
