  • Publication number: 20150059261
    Abstract: A lifting apparatus to be embedded within a precast concrete panel or slab to enable the panel to be lifted, positioned atop a road bed, and elevated above the road bed. A lifting apparatus is located at each corner of the panel. Each lifting apparatus has a threaded sleeve extending through the panel to receive a removable threaded lifting bolt by which to establish a lifting point at which a lifting force is applied to lift and position the panel. When the threaded lifting bolt is rotated completely through the threaded sleeve, a pushing force is applied against a base plate, whereby to elevate the panel above the road bed as is necessary to make the panel level with adjacent panels during the construction or repair of a roadway. Grout is pumped through the panel to fill the space between the panel and the road bed.

  • Publication number: 20110311309
    Abstract: A wing blade attachment for a motor grader used to maintain unimproved rural roads. The wing blade attachment mounts to a trailing end of a main motor grader blade and swings up and down into ground scraping contact in order to create water drainage passages through the gravel windrows along the road edges or to smooth roadways at intersections, bridges and driveways. The windrows are placed by road maintenance crews to stockpile materials for roadway use. A linear actuator such as a hydraulic ram allows the grader operator to remotely and selectively swing the wing blade up and down and cut passages.

  • Patent number: 7614821
    Abstract: This invention relates to an impact compactor including a wheeled chassis structure and at least one non-round roller carried on an axle assembly. The axle assembly is rotatably mounted on a drag link, which is pivotally mounted on the chassis structure. The compactor includes also a lifting arrangement for lifting the roller from the ground, including a lifting arm, located above the drag link and pivotally displaceable with respect to the chassis structure, and a piston/cylinder mechanism for pivoting it. The lifting arm has a depending lifting formation that can releasably engage either one of the drag link and the axle assembly carried by the drag link for raising the roller from the ground. The configuration of the lifting arrangement provides for suitable accommodation of the piston/cylinder mechanism, which is problematic in some conventional-type compactors and associated with certain risks of mechanical failure during compaction operations.
