Rolling device comprising a housing (11) accommodating a rolling element and a control and communication module comprising a wireless receiver (30) connected to a control device (40) and position means (50) connected to the control device, wherein the rolling device further comprises driving means (60) connected to the control device and the rolling element for driving and controlling the movements of the rolling element according to a first position acquired by the position means and a received wireless signal comprising movement instructions and a second position, power supply means (70) for powering the control and communication module and the driving means, wherein the housing is arranged with an support assembly for bearing the rolling element which is configured for establishing a releasable connection with the housing, and an electrical interface adapted for establishing connection between the rolling element and the control and communication module and the power supply means.

A spring-force adjustable, height-adjustable industrial caster assembly including a mounting plate, a swivel housing that swivels relative to the mounting plate, and a spring assembly having components that are moveable relative to the swivel housing to controllably alter spring deflection and/or caster wheel height, which components can be adjusted by accessing the height-adjustable industrial caster assembly from above, eliminating the need to raise a pallet truck or other moveable assembly to which the caster assembly is coupled, away from the floor to be able to access and adjust the industrial caster assembly.

A caster device includes a caster wheel configured to rotate around a horizontal rotation axis; and a case configured to expose a lower surface of the caster wheel, cover the caster wheel and have an inclined surface from a top of the horizontal rotation axis toward a bottom of the horizontal rotation axis.

A caster wheel assembly for an outdoor power equipment machine includes a wheel mount and provides a double bell-shaped caster wheel including two bell-shaped halves, each bell-shaped half includes a central hub, a smooth transition portion, an outer circumferential rim, and a planar face. A ground contacting tread can be provided by the outer circumferential rims. A ground contacting tread can be provided by a resilient tread ring positioned between the two bell-shaped halves.

A rolling device having a bearing housing accommodating a wheel axle, a drive motor with first and second motor parts for conduction of relative rotation between a wheel element and the wheel axle, end portions of the wheel axle being connected to axle support members in an eccentric position displaced from the center line of the axle support members, and locks operable between an unlocked position allowing rotation of the axle support members relative to the bearing housing, and a locking position preventing the rotation of the axle support members, wherein in the unlocked position, the motor conducts rotation of the axle support members and wheel axis for displacement of the wheel element by an eccentric movement between an extended position where at least a portion of the wheel element projects outside the bearing housing and a retracted position where the wheel element is located inside the bearing housing.

In a method for monitoring an electromagnetically actuable brake, which has an energizable coil that interacts with a tractive electromagnet situated so as to be linearly movable, and a vehicle having an electromagnetically actuable brake, the current flowing through the coil is acquired, the acquired current value in particular being conveyed to an evaluation unit, the voltage applied at the coil is intermittently increased, and a relative position of the tractive electromagnet with respect to the coil is determined from the thereby induced current characteristic, in particular the characteristic of the current rise, it is particularly determined from the ascertained position whether the brake is in the applied state or in the released state, the tractive electromagnet in particular is arranged as a permanent magnet or has a permanent magnet.

An articulating carriage for moving an object across a surface having a non-planar obstruction to allow movement of the object over the obstruction. The articulating carriage has a walking beam assembly that pivotally supports a pedestal to dispose a support surface thereof above the walking beam assembly. The walking beam assembly has a base plate, wheeled casters and a pair of spaced apart hangers having articulation openings. The walking beam pivots relative to the pedestal. In one embodiment, the pedestal is pivotally mounted on the walking beam assembly. In another embodiment, a pair of walking beam assemblies are connected with a crosstube that pivotally supports the pedestal. In another embodiment, a major crosstube assembly connects a pair of crosstubes to define a carriage having four walking beams. In yet another embodiment, a compound crosstube assembly connects pairs of major crosstube assemblies to define a carriage having eight walking beams.

A roller assembly comprises a housing having an outer surface attached thereto, and a braking arrangement positioned at least partially within the housing. The braking arrangement is configured to increase resistance to rotation of the housing proportionally to a load applied against the outer surface.

An AGV including a support structure and at least one drive unit connected to the support structure, wherein each drive unit includes a wheel rotatable about a wheel axis and about a steering axis perpendicular to the wheel axis; a wheel motor arranged to drive the wheel about the wheel axis; and a steering motor arranged to drive the wheel about the steering axis; wherein the AGV further includes at least one actuation member movable in an additional degree of freedom; and wherein the at least one actuation member is arranged to be driven by the wheel motor and/or the steering motor of at least one drive unit in the additional degree of freedom. A method of controlling an AGV is also provided.
