Abstract (en)
The basket comprises claws (1, 2) for support on a ladder (15) capable of being disengaged under the effect of an upward traction transmitted by means of a movable bar (3) and a spring (5). A locking means is provided which is capable of engaging the claw in the support position by a downward movement of a bar (4) which is movable with respect to the chassis of the basket. The locking means furthermore comprises a spring (6) attached on the one hand to the bar (4) and on the other hand to an element (9) integral with the basket, this spring being stretched or compressed when the claws (1, 2) are disengaged. <IMAGE>
