1. A catching device for a traveling body comprising:
first and second retaining means,
the first retaining means actuatable between a blocked state and an unblocked state and being adapted, in the blocked state, to clamp and retain the traveling body on a first rail;
the second retaining means actuatable between a blocked state and an unblocked state and being adapted, in the blocked state, to clamp and retain the traveling body on a second rail;
where the first retaining means and the traveling body are slidable relative to one another within a limited first sliding displacement in a direction of movement of the traveling body along the first rail when the first retaining means is mounted on the traveling body,
and where the second retaining means and the traveling body are slidable relative to one another within a limited second sliding displacement in a direction of movement of the traveling body along the second rail when the second retaining means is mounted on the traveling body,
and the limited first sliding displacement is longer than the limited second sliding displacement by an incremental distance,
wherein, to actuate the first and second retaining means from the blocked state to the unblocked state, the traveling body is set in motion relative to the first and second retaining means, and when the traveling body traverses the limited second sliding displacement the second retaining means is released from the second rail into the unblocked state, and when the traveling body further traverses the incremental distance the first retaining means is released from the first rail into the unblocked state.
