A high load pivoting caster with integral jack preferably includes a wheel mounting base, a pair of wheels, a high load jack, a slewing ring, an wheel axle and an attachment cube. The wheel mounting base includes a base plate, and first and second pairs of wheel support plates. The first wheel is retained between the first pair of wheel support plates. The second wheel is retained between the second pair of wheel support plates. The wheel axle is inserted through the pair of wheels and the first and second pair of wheel support plates. The slewing ring preferably includes a stator ring, a rotor ring, an indexing plate and a set of rotary bearings. An opening is formed through the indexing plate to receive an outer perimeter of the high load jack. The attachment cube is preferably attached to a top of the indexing plate with welding.

A caster assembly comprises a caster wheel having an outer surface. A wheel support is coupled to the wheel to support the wheel for rotation about a rotational axis and for swiveling about a swivel axis. A brake assembly comprises a brake having a cammed wheel engaging surface shaped to engage the outer surface of the wheel and a brake actuator to move the brake relative to the wheel from an unbraked position to a braked position in which the brake limits rotation of the wheel about the rotational axis. The cammed wheel engaging surface is arranged to articulate relative to the wheel support. The cammed wheel engaging surface articulates relative to the wheel support in response to the wheel rotating about the rotational axis after the brake is initially placed in the braked position such that the cammed wheel engaging surface more deeply engages the wheel with rotation of the wheel about the rotational axis.

The invention provides a caster comprising a bracket, a first transmission device and two wheels. The two wheels are connected by a transmission screw and are fixed to the bracket. The first transmission device comprises an annular retaining portion and a plurality of first balls, the plurality of first balls are equiangularly arranged in a circumferential direction of the annular retaining portion, and opposite sides of the annular retaining portion are respectively embedded in the respective wheels. The caster of the invention can solve the problems in the prior art that it is difficult to control the gap between the two wheels, the resistance generated between the two wheels is large and noise is easily generated.

Disclosed is a level castor including: a castor main body which has a socket shape having an opening, and in which a wheel contacting the ground is mounted therein and rotatably hinge-coupled to one portion of the lower side thereof; a connection frame which is rotatably connected to the castor main body and fixedly mounted to a weight disposed thereabove, thereby connecting the castor main body to the weight such that the castor main body can rotate with respect to the weight; a support body provided to the castor main body through the opening in a retractable manner so as to contact the ground; and an adjustment unit which is provided in an inner accommodation space of the castor main body, and which retracts the support body through a rotation operation of a rotation handle.

A caster wheel that locks and unlocks using a push-lock, push-unlock mechanism, similar to a push button pen. The mechanism can be placed on the side of the wheel to be easily accessible to the user and to allow a convenient locking of the caster wheel.

A magnetic drive has a prime mover, having a first magnet array on a first surface thereof, and a rotor, having a second magnet array on an outer surface thereof. The outer surface of the rotor is located adjacent to the first surface of the prime mover such that movement of the prime mover causes rotation of the rotor about an axis of rotation. A support member has a shaft for defining the axis of rotation of the rotor, and having a third magnet array, and the third magnet array cooperates with a fourth magnet array on the rotor to form a magnetic bearing to resist forces on the rotor acting along the axis of rotation thereof.

A caster wheel that locks and unlocks using a push-lock, push-unlock mechanism, similar to a push button pen. The mechanism can be placed on the side of the wheel to be easily accessible to the user and to allow a convenient locking of the caster wheel.

A caterer buffet table conversion kit comprises detachable one piece spring handles for transport and exchange of chafing dishes, and low profile table casters. The components of the kit have utility individually. The handles are each formed from a one piece spring steel and include a semi-cylindrical grip, an upper and a lower leaf with the lower having a spring forming member facilitating the engagement of the chafing pan between the leafs. Each caster includes a caster assembly including a caster wheel or caster ball and a tubular table coupling bracket coupled thereto and configured to receive a conventional table leg therein. The bracket is offset from a caster wheel or caster ball and configured to receive the table leg wherein a terminal end of the table leg is positioned vertically below the center of the caster wheel or caster ball to minimize the height of the table top.

A caster apparatus is provided. In one embodiment, there is provided a caster apparatus including a caster wheel and a first driving wheel disposed on a first side of the caster wheel. The first driving wheel is configured to be driven by a first motor. A second driving wheel is disposed on a second side opposite to the first side of the caster wheel. The second driving wheel is configured to be driven by a second motor different from the first motor. A first actuator is configured to move the first driving wheel in a vertical direction to a ground according to a curvature of the ground. A second actuator is configured to move the second driving wheel in a vertical direction to the ground according to a curvature of the ground, wherein the first and second driving wheels are configured to steer the caster wheel.

A caster for equipment and furniture, the caster comprising a support element including a top element and a base element, wherein the top element includes an attachment bolt configured to attach the caster and the base element includes a wheel axle that supports at least one wheel, wherein a replaceable substantially circumferential one-piece support element cover made from a synthetic material that provides a continuous design surface is arranged at the support element.
