Transport trolley chassis for e.g. workshop, has guiding bearings maintaining guiding carrier wheel rotating around rotation axis, and switching units to switch guiding bearing between inhibition and functional guiding states

摘要

The chassis (2) has guiding bearings maintaining a guiding carrier wheel (41) rotating around a rotational axis (310) which extends along an extension line to a preset azimuth orientation. Switching units (65, 311) are provided to switch the guiding bearing (31) between an inhibition state and a functional guiding state, in the functional position of the chassis.
