Abstract
The present invention relates to an aerial lift (1), which includes: a lower portion (2, 3) provided with members (7) for connecting to the ground (S); a lifting structure (4); a platform (5) supported by the lifting structure (4); and a lighting system (20) including at least one lighting device (21, 22, 23) arranged on the lower portion (2, 3) or on the platform (5), other than a driving light. The aerial lift (1) is characterised in that the lighting device (21, 22, 23) selectively generates coloured light beams, the colour of which are selected among at least two distinct colours, respectively corresponding to an “emergency stop” situation (C2) of the aerial lift (1) and an “accident at height” situation (C4) of the aerial lift (1). The invention also relates to a method for implementing such an aerial lift (1).
