Abstract: The invention relates to a sliding step for a public transit vehicle, which sliding step comprises a tread plate that can be horizontally extended or retracted by means of a drive, with two lateral arms and a tread surface arranged between the lateral arms, whereby the tread plate is provided with at least two rollers associated with the lateral arms, which rollers run on a track attached to the vehicle. At least one of the lateral arms in the area of the rollers is provided with an offset section arranged between the two rollers and comprising a strain gauge element for detecting deformations.

Abstract: An electromechanical device for activating a rotating post that moves the leaf of a swinging door on a vehicle, especially a mass-transit vehicle. An electric motor activates the column by means of an intermediate worm gear. The motor outtake shaft is coupled to the worm-gear intake shaft. A worm wheel is coupled to the worm-gear outtake shaft, which activates the rotating post. The electromechanical activating device contains an emergency mechanism for uncoupling the worm-gear outtake shaft from the worm wheel in relation to their rotation. The mechanism incorporates a coupling that can be disengaged between the outtake shaft and the worm wheel, which is mounted over it coaxially. The mechanism also involves several balls situated such that they can be forced into recesses in the outtake shaft while simultaneously engaging axial grooves in the inner surface of the worm wheel.
