A sheath for a soil working roller (20) of a soil processing machine, said sheath is rotatable about a roller axis of rotation and comprises a plurality of sheath segments (40), mounted or mountable to surround a roller body (22) of the soil working roller (20) and following one another in the circumferential direction, wherein a plurality of roller tools (48) is arranged on an outer side of the sheath segments (40) positioned to be facing away from the roller body, wherein at least one part of the roller tools (48) comprise an interchangeable holder mounted on a respective sheath segment (48) and a replaceable tool detachably mounted or mountable on the interchangeable holder of the same, wherein a fastening opening is formed in the interchangeable holder for accommodating a fastening shaft of a replaceable tool mounted or to be mounted on the interchangeable holder, wherein a tool through opening (84) is provided in association with the at least one interchangeable holder in the sheath segment (40) supporting the same.

A materials handling equipment has blades of a lifting fork wherein each of the blades engages a blade wheel that moves between a retracted position when the blade is lowered and an extended position when the blade is raised to lift and support a load. The blade wheels have a plurality of tires linearly aligned on a common axis, the tires each having a circular circumference and a sinusoidally varying peripheral surface. The sinusoidally varying peripheral surfaces have relative peaks and valleys uniformly spaced around the circular circumference wherein the peaks and valleys are mutually nested.

The present invention is related to durable, increased traction irrigation wheel systems and method of increasing traction and durability of an irrigation wheel. A segmented, fully enclosed, circular rotating drum may be provided with may be configured to rotate around a central axis. A system may have integrally placed flat sheets on a periphery of a segmented, fully enclosed, circular rotating drum, at least one traction projection, and perhaps even at least one influential traction enablement component.

A circular wheel is aligned in a rotational plane and has a peripheral outfacing surface symmetrical about the plane of rotational. A center line of the width of the peripheral outfacing surface is sinusoidal around the wheel. The wheel may have a central hub, a rim, a medial wheel structure between the hub and the rim, and a tire mounted on the rim. The outfacing surface may be that of the hub, the medial wheel structure, the rim, or the tire depending on the application.

A center pivot irrigation system wheel including a hub having an axis of rotation and having lateral and oppositely lateral sides; a plurality of spoke pairs having distal ends and having proximal ends, each proximal end being attached to the hub, each spoke pair having lateral and oppositely lateral spokes, each lateral spoke being intersected by an axially extending plane of orientation, and said each oppositely lateral spoke being intersected by the same plane of orientation; a first plurality of axially extending through spaces, each through space being bounded by an adjacent pair of the spoke pairs; an annular rim having an outer surface, the distal end of each spoke being fixedly attached to the rim; and a plurality of treads, each tread being fixedly attached to the annular rim's outer surface.

A tireless steel wheel for a skid steer features a cylindrical drum, a set of cleats projecting externally from the drum, a hub plate inside the drum an at intermediate location between opposing ends thereof, frustoconical walls flaring outward from opposing sides of the hub plate toward the respective ends of the drum, and annular end plates joining the wider ends of the frustotonical walls to the drum at the opposing ends thereof. The hub plate is offset from an axial center of the drum, and the frustoconical walls are unequal to one another in their angle of taper. The annular walls prevent the wheels from digging into the ground, and the frustoconical walls prevent material accumulation inside the wheels. The offset position of the hub plate provides flexible mounting options to accommodate varying dimensional characteristics of different skid steer models and bucket sizes.
