Abstract
In a ladder assistance device, a cable pulled by a controlled driving apparatus is laid in a loop along the height of the ladder, the user being attached to the cable by a lanyard, a sensor element detecting movements along the ladder, a control element controlling the driving apparatus. A remote control activates or deactivates assistance and allows user weight input, the remote control remaining in the reach of the user and including a stop button deactivating assistance and two activation buttons for activation of assistance, one each for “up”/“down”. A memory stores sets of control values for assistance level(s) for each direction of movement, corresponding to at most two levels in the steady state of the assistance. The program of the control element allowing: the selection that corresponds to the user weight, the activation which is only obtained by the activation buttons of the remote control.
