A scraper bowl structure (11) for use in a scraper vehicle (10) having a rear wheeled support (12) and a wheeled tractive unit (15). The bowl structure (11) is defined by sidewalls (16,17) pivotally mounting a front apron (22) and a rear blade (25). Positioning devices (29,30) are associated with the apron (22) and blade (25), respectively, selectively positioning the apron (22) and blade (25) in raised and lowered positions. Spreader elements (19,20,21) for securing the sidewalls in spaced relationship further serve as supporting elements for supporting the blade (25) in the different dispositions thereof. The configuration of blade (25) is preselected so as to bulldoze earth forwardly onto the apron (22) in a lowered position of the blade (25) and apron (22).
A damping device for use with a conventional dirt bucket on a dirt mover which includes a skid shoe hingedly attachable to the bucket by means of a hinge at the front end of the skid shoe, the skid shoe having a wear plate attached to the bottom. The skid shoe with wear plate attached is attachable to the back of the bucket by a spring loaded leg removably connected to an outer sleeve which substantially encloses the spring loaded leg and which is rigidly attachable to the back of the bucket.
A control system to automate operations for wheel tractor scrapers. The control system simplifies the operation of the wheel tractor scraper by automating the many operations of the wheel tractor scraper which alleviates the operator from many of the operations of the wheel tractor scraper during the use thereof. The control system has a load control module, a haul control module associated with the load control module and an eject control module. The eject control module is associated with the load control module and the haul control module. The load control module, the haul control module and the eject control module control the loading, hauling and ejecting operations of the wheel tractor scraper.
This device is a vehicle for scraping earth from regions containing land mines or munitions. The scraped earth is separated into munitions and earth, the earth is allowed to exit the vehicle's scraper bowl. The munitions and land mines are retained in the scraper bowl. The device is additionally armored in those regions where explosion of the cargo carrying, e.g., land mines, is found. Additionally, the device may be robotically operated.
An apparatus for lifting and aligning a blade to a support, such as a grader moldboard or a scraper bowl. In one aspect the invention is an apparatus with a frame, flexible hoisting means for holding the blade, a drum to which each flexible hoisting means is attached, a stabilizing means for stabilizing the apparatus, and a drive means for rotating the drums. In another aspect, the invention is a method for lifting a blade to a support, which involves inserting flexible hoisting means through different apertures of a support and the corresponding apertures in the blade, and providing means to controllably reduce the length of the flexible hoisting means while holding the blade. The apparatus and method can be used by one person to lift, line up, and securely bolt a blade to a support.
