Abstract: A selectively locking rotational bearing element includes at least one bearing element supporting an outer race for rotational movement and a plurality of locking elements disposed circumferentially about an inner surface of the outer race. An actuator selectively moves the plurality of locking elements into engagement with the outer race to restrict rotational movement of the outer race and selectively move the plurality of locking elements away from engagement with the outer race such that the outer race is free to rotate relative to the locking elements.

Abstract: A crane for lifting and transporting loads includes a handling element, for supporting and handling the loads, and a chassis for transferring the loads of the crane onto a support surface by a contact arranged in contact with the surface, such as wheels. A drive transmission, such as a drive wheel, moves the crane on the support surface. The drive transmission is capable of translating relative to the chassis to adjust the force exerted by the drive transmission upon the support surface. The crane includes a sensor for detecting the force exerted by the drive transmission upon the support surface; and a control unit configured for adjusting the position of the drive transmission relative to the chassis, based on the detection of the sensor.

Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support frame to influence motion of the patient transport apparatus over a floor surface. The auxiliary wheel is movable to a deployed position with the auxiliary wheel engaging the floor surface and a stowed position with the auxiliary wheel spaced a distance from the floor surface. An actuator assembly including a lift actuator a biasing device, and a biasing load adjustment assembly. The lift actuator is operable to move the auxiliary wheel to the deployed position and to the stowed position. The biasing device configured to bias the auxiliary wheel towards the deployed position. The biasing load adjustment assembly configured to adjust a biasing force being applied by the biasing device to the auxiliary wheel.

Abstract: A roller has a wheel, a wheel axle and a pin which protrudes upward from a housing of the roller. A sleeve sits on the pin and is spaced apart from the pin radially and axially upward by a damping material arranged between the sleeve and the pin, the damping material being arranged so that all axial and/or radial contact between the pin and the sleeve is prevented. Alternatively, an attachment damping part can be arranged on a pin of the roller in overlap with the pin, wherein the attachment damping part has an inner sleeve and an outer sleeve, the inner sleeve being spaced apart radially and axially upward by a damping material arranged between the inner sleeve and the outer sleeve. The damping material is arranged in such a way that all axial and/or radial contact between the inner sleeve and the outer sleeve is prevented.

Abstract: A patient support apparatus comprises a base supported by caster assemblies with each caster assembly comprising a stem, a caster wheel, and a caster wheel axle. A patient support surface is coupled to the base and is configured to receive a load. One or more load sensors are integrated with at least one of the stem, the caster wheel, or the caster wheel axle for measuring the load. One or more of the caster assemblies can be coupled to a steering motor, which controls orientation of the caster assembly. A controller can control the steering motors based on analyzing the measurements of the load sensor. The load sensors can produce measurements indicative of both vertical load and non-vertical load applied to the caster assembly. The controller can also analyze the measurements of the load sensor to determine the load received by the patient support surface by negating the non-vertical load.
