    Abstract: A vibratory plate compactor with aggregate feed system includes a frame, a soil compacting plate and a drive mechanism, such as a hydraulic motor, is mounted on the frame and has a rotatable drive shaft which uses a V-belt to drive a vibratory actuator on the tamping plate. The frame also carries a hopper that uses a screw conveyor to force the stored aggregate into a vertical conduit. A tamping piston forces aggregate out of the vertical conduit, through apertures in the compactor plate and compacts the loose soil with a multitude of blows, the vibratory plate is then actuated to further compact the aggregate. The process is repeated until the cavity is filled and compacted to the required density. The vibratory plate compactor with aggregate feed system is ideally suited to filling and compacting aggregate in used automobile tires that are used in the formation of a tire wall.

  • Patent number: 6422785
    Abstract: An infeed conveyor is provided with high pivot capability. High pivot capability is the capability to raise the elevation of at least one end of an infeed conveyor belt to an elevation higher than regular horizontal operation if the belt placer is operating lower than the surrounding grade. High pivot capability prevents the infeed conveyor from bottoming out on the grade of the haul road or adjacent pavement; and in some instances, high pivot capability allows use of the belt placer under conditions that belt placers without high pivot capability could not operate. Also disclosed is the ability for belt placers to be used to pave in both forward and reverse directions, whereas former belt placers could only pave in the forward direction. This is accomplished by the ability to rotate the discharge conveyor under one side of the belt placer, and changing the direction in which the belt placer travels.

Adjustable indicators on the flame indicate the relationship of the aggregate surface to a desired aggregate height with subsequent operation of the actuators lifting or lowering the blade assembly to raise or lower the blade assembly strike off action for return of the indicators to a predetermined relationship to guides, shown as concrete forms, extending along the course of the aggregate being laid. A vibratory compactor trails the shoe and may move about multiple axes. The shoe supported actuators may be operated in a uniform or differential manner, the latter resulting in transversely tilting the blade assembly for transverse sloping of the aggregate surface.

  • Patent number: 6213681
    Abstract: A soil compacting device has a damping system which couples an upper mass and a lower mass together with a spring system in a vibration system. The damping properties of the damping system can be modified while the device is in operation. Therefore, when the soil compacting device passes over soils having different properties, it can constantly be adjusted in an optimal manner to the ground underneath it by acting on the vibration properties of the overall vibration system.

  • Patent number: 5567075
    Abstract: A laser controlled automatic grade control system for finishing plastic concrete mounts the finishing tool behind the support towers to resist furrowing. The system functions with a variety of elongated, multi-section concrete finishing tools such as triangular truss screeds or the like, all of which can be quick connected or disconnected from the tower system. Skis that support the device facilitate sliding, winch-driven movement over and through plastic concrete. Spaced apart, vertically upwardly extending towers support the device along the length of the finishing tool. The towers are cylinder-adjustable in length. Cylinder extension and retraction are governed by a sensor-controlled system that is laser operated. The sensors respond to a preestablished laser beacon to control finishing tool elevation as the device traverses the pour in response to its winches.

  • Patent number: 5540519
    Abstract: An extremely light-weight, portable floating power vibratory concrete "Wet Screed", which is hand operated by a single finisher in order to strike off, tamp and smooth freshly poured concrete using only perimeter slab forms or curbs. The unique angular design of the enclosed hollow screed blade allows the operator to lower the handle and effectively use the rear 60 degree angled surface of the screed blade to cut down the height of the concrete to the desired grade, or raise the handle to effectively use the front 60 degree angled surface of the screed blade to float and maintain the desired grade. The flat aluminum bottom extending from the front angled surface to the rear angled surface of the screed blade functions to produce a smooth, near final finish while the vibratory action tamps the rock down and works the fat to the concrete surface, thereby substantially increasing the finishing time while making the finisher's job much easier.
