The aerial lift comprises: – a platform (3) provided with a guardrail (8a, 8b) and a mechanism for lifting this platform; – a desk (100) for controlling the movements of the aerial lift, – one or more virtual-barrier systems (B101; B102; B103) for determining that an individual on the platform is close to a part of the guardrail adjacent to the desk and/or is leaning towards the desk, by detecting interference between the individual and the virtual barrier, the system inhibiting at least certain movements of the aerial lift if it detects interference with the barrier. The virtual-barrier system comprises at least one emitter and one receiver of waves, the system detecting interference of an external object with the barrier by the fact that the receiver receives waves emitted by the emitter by reflection off the object that is interfering with the barrier.
