Abstract: A roller unit for a vehicle includes a retaining member, at least one wheel rotatable relative to the retaining member about an axis of rotation, at least one brake unit for braking the at least one wheel and a ventilation device for manually ventilating the brake unit. The brake unit has a tie rod which is translationally displaceable, relative to the retaining member, between an upper end position, in which the brake unit is released, and a lower end position, in which the brake unit is actuated. The ventilation device has a lever including a first lever arm and a second lever arm, a lever fork, which is arranged on the second lever arm, and a locking device. The lever is swivelable relative to the retaining member about a lever axis, between a ventilation position and a working position.

Abstract: A device for holding objects, e.g., driverless transport vehicles, includes a rack main frame and a pivot arm which can be pivoted relative to the rack main frame about a pivot axis extending in a longitudinal direction. The pivot arm has a first strut and a second strut which extend at a right angle to the pivot axis and are disposed parallel to each other at an offset in the longitudinal direction. One cutout is provided in the end region of each of the struts remote from the pivot axis for receiving respective fastening shafts.

Abstract: A mobile transport system includes a drive unit having a first drive wheel rotatable about a first drive axis and a second drive wheel rotatable about a second drive axis, the drive axes extending in a transverse direction. The drive unit includes a swivel and a drive frame. The drive frame is pivotable about a steering axis relative to the swivel. The drive unit includes a marking carrier that is disposed in a stationary manner relative to the drive frame, and on which optically detectable markings are applied. The drive unit includes a camera for detecting the markings and is disposed in a stationary manner relative to the swivel.

Abstract: A mobile transport system includes a vehicle frame, first and second pairs of support wheels, first and second drive wheels, and a swing frame pivotable about an swing axis relative to the vehicle frame. The first support wheels are disposed on the vehicle frame, and the second support wheels are disposed on the swing frame. A drive unit including a drive frame is disposed on the swing frame. The first drive wheel is rotatably supported on a first swing arm pivotable about a first swing axis relative to the drive frame, and the second drive wheel is rotatably supported on a second swing arm pivotable about a second swing axis relative to the drive frame. The drive frame is pivotable about a steering axis relative to the swing frame.

Abstract: A mobile transport system for transporting objects in a technical system, includes a vehicle frame, a first wheel pair, a second wheel pair, and a third wheel pair, each having two wheels rotatable relative to the vehicle frame, and a swing frame pivotable about a swing axis extending in a transverse direction relative to the vehicle frame. The first wheels of the first wheel pair are attached to the vehicle frame, and the second wheels of the second wheel pair are attached to the swing frame. The third wheels of the third wheel pair are attached to a tilt frame pivotable relative to the swing frame about a tilt axis extending approximately in the longitudinal direction.
