A securing mechanism for securing thereto a load. The securing mechanism comprises a locking member having at least one planner with a peripheral shape, a cam follower mechanism having a follower with a load facing end and being configured to translate a linear displacement along an axis being perpendicular to said load facing end to a rotational movement thereof about said axis, and being so disposed relative to said locking member such that said rotational movement thereof sequentially shifts said locking member between a released position in which at least one dimension of said peripheral shape has a first size and a secured position in which said dimension has a second size, said second size being larger than said first size.
