<p>Wheels (25) are placed on clevis (4) able to rotate at end of arm (21) on transversal pivot (40), under action of actuator ( Actuator links clevis to arm so as to modify position of wheel relative to plane defined by arms. When pole (24) is folded, actuators (41, 28) allow folding of wheels (25, 26) above plane inferior to base (20) of frame (2), so as to reduce height of lifting truck (1).</p> |
