  • Patent number: 4530620
    Abstract: A landfill compactor vehicle comprises two forward wheels and two rear wheels, each wheel having on its rim teeth having a substantially arrowhead configuration, when viewed in plan, each tooth having at least a slicing portion and a tamping portion, the teeth are arranged in a twin helical turbine pattern around the wheel rim. The disposition of the teeth pattern and the attitude of the teeth for each wheel is different to that of the other three wheels and this taken with the aforesaid arrowhead configuration of the teeth ensures a mincing action on refuse, waste and soil over which such a landfill compactor vehicle is driven.

  • Patent number: 4490070
    Abstract: A compactor assembly and method of utilization thereof to compact soil in a trench are provided that do not require the hydraulic boom to which the compactor assembly is mounted to exert downward pressure to effect compacting. A sheep's foot roller defined by a cylindrical surface with a plurality of feet extending radially therefrom is mounted for rotation with respect to an axle having a length less than the length of the roller. The axle is completely contained within the interior volume defined by the roller's cylindrical surface. A frame operatively mounts to a crawler excavator or the like, the frame including a pair of side plates, a top plate, and back plate, and the axle is mounted to the frame side plates so that the axle remains stationary with respect to the side plates and the roller rotates about the axis defined by the axle. Each of the feet comprises a solid member tapered to a truncated apex in a circumferential direction, and having a pair of parallel flat spaced sides in an axial direction.

  • Patent number: 4411081
    Abstract: A sheepsfoot assembly including a sheepsfoot frame section, an engine housing section with protective canopy, a vibratory sheepsfoot drum assembly mounted in the frame section, the drum assembly containing a rotatable drum with an internal bearing and eccentric shaft assembly and a plurality of spaced compacting teeth on the drum. The sheepsfoot drum is rotated when the machine is pushed or pulled over the soil by the prime mover to which the sheepsfoot assembly is attached. The drum is not powered for rotation, but only for vibration by the engine assembly.The sheepsfoot frame includes a mounting jaw arrangement for securing the machine to the integral lip of certain prime movers, e.g., front end loader, or to an added lip as for attachment to dozer blades. In this manner, the prime mover can straddle a trench and the sheepsfoot assembly can be then lowered into the trench until it contacts a backfill layer for soil compaction.

  • Patent number: 4302129
    Abstract: A vibratory compacting roller adapted to be coupled to a prime mover and equipped with hydrostatic drive and vibrator, both drivingly connected to a hydraulic power generator located on said prime mover, is provided with recessed tamping elements distributed in parallel adjacent rows around the periphery of the roller cylinder face with a peripheral offset between adjacent rows. The tamping elements are of trapezoidal design with a semi-circular recess extending centrally from the base to the short side, said recess rendering a vibrational compacting roller with tamping elements equal in weight to a plain vibratory compacting roller of the same over-all diameter.

  • Patent number: 4281945
    Abstract: Roller assemblies for refuse crushers or the like are provided wherein a roller element having axial end faces and a cylindrical surface carrying refuse crushing means is provided. Structure for supporting the roller element includes a pair of end faces, each of which is situated in opposed, spaced relation to a corresponding one of the axial end faces of the roller element. Crushing apparatus is provided on the opposed end faces of the roller element and support structure which crush refuse which might enter the space between the roller element and the support end faces.

  • Patent number: 4278368
    Abstract: PCT No. PCT/US79/00495 Sec. 371 Date July 11, 1979 Sec. 102(e) Date July 11, 1979 PCT Filed July 11, 1979A compacting apparatus (10) has an impact apparatus (17) and a compactor (19). The impact apparatus (17), such as, for example, a rock breaker, provides impacting forces on the compactor (19). The compacting apparatus (10) is positioned on, for example, a work structure (12,14,15) of a work vehicle (16). It is necessary to compact material in order to provide, for example, proper filling of a trench (74) after a pipe has been placed in the trench. Compaction, as done by the compacting apparatus (10), is provided by simultaneously compacting the material and applying a compressive force to the material and remolding the material. Therefore, satisfactory compaction can be provided in the trench (74) by the work vehicle (16) which is also usable to excavate and refill the trench (74).

  • Patent number: 4269535
    Abstract: An operating and down-pressure hydraulic control system for vehicle-mounted implements such as earth compactors and the like. The assembly of hydraulic cylinders, valving and a hydraulic accumulator provided herein operates as a hydraulic system to raise, lower and otherwise position an implement and to provide down-pressure to it. The assembly also permits the hydraulic support of the implement to flex, while maintaining down-pressure on it, when the ground surface elevation rises or falls away relative to the implement as it moves over the ground being worked.

  • Patent number: 4074942
    Abstract: A compactor wheel comprises sets of tips each disposed in circumferential alignment therearound with the leading edge of a tip of one set being substantially aligned with the trailing edge of a tip of an adjacent set. Each tip comprises a body portion having a cross-shaped tip portion secured in upstanding relationship thereon to include a first tip portion extending circumferentially and a second tip portion extending transversely relative to the first tip portion and disposed intermediate the ends thereof. A tapered surface and concavity are formed on each lateral side of the first tip portion to dispel material outwardly therefrom during compaction of soils or the like. A plurality of circumferentially aligned blades are positioned on each lateral side of the compactor wheel.

  • Patent number: 4066374
    Abstract: A vibratory sheepsfoot is attached to a coupling assembly that is mounted on a hydraulically operated tool bar on the back of a tractor. The coupling assembly is designed to permit adjustability of the vibratory sheepsfoot in a vertical direction. The coupling assembly is mounted on the tool bar such that it can be moved along the length of the tool bar to a desired position. The apparatus is especially useful in compacting earth in a trench offset to the side of the tractor.

  • Patent number: 4066375
    Abstract: A replacement cap for use on the tip of a compaction wheel foot. The cap includes a pair of half-caps weldable together on the end of the tip. The half-caps are generally rectangular and are formed with inner end portions having facets which abut to form V-shaped weld pockets. The half-caps are shaped so as to snugly fit on tips having varied wear patterns. Replacement time, weld material and replacement costs are thereby reduced.
