Abstract

An on-board electronics system of an aerial work platform moves the wheels between a retracted and extended position by pivoting a respective arm. The method comprises the following successive steps: a) orienting each wheel tangentially to the pivoting path of the corresponding arm, b) moving the wheel by pivotally actuating the corresponding arm, and c) reorienting the wheel so as to enable another translation of the aerial work platform. The steps are performed in different orders between the wheels so that at any time at least one of the following conditions is complied with: —the brake system of at least one wheel is active, —at least one wheel is rotated by a motorised drive, —the orientation of the wheels relative to one another prevents any translation of the aerial work platform ( 1 ) on the ground as a result of gravitational force.
