Stacking boxes
Crate stacking (in Switzerland : crate stacking ), also called crate climbing , is a leisure activity that is more often carried out at larger, public festivals, in which crates of drinks are stacked on top of one another by a person on top of the crate tower .
execution
The goal of box stacking is to stack as many boxes as possible on top of each other before the tower wobbles and falls.
Since it is usually stacked up to the fall, the stacking person is always secured with a harness and climbing rope so that they do not fall, but hang in the rope and can be slowly lowered back to the ground . The required deflection point for the safety rope should be above the highest point that the stack of boxes can reach. Since it is mostly in the climbers to persons without a fall experience in lead climbing is, the turning point may not be climbed over. When belaying, the rope elongation and the yielding of the belay must be taken into account. Cranes , turntable ladders , trees or buildings with sufficient security options are suitable for suspension . The multiple weight force of the climber acts on the deflection point, so that the deflection point must have a minimum load of 25 kN. For safety reasons, only experienced and trained persons should secure.
Often it is enough to hand or toss the boxes to the climber; at greater heights, a handing bar or a cable lift has proven itself.
Especially the person who anreicht the climber the boxes should a helmet wearing; this may also be necessary for the belayer, depending on the distance from which he is securing. The audience should keep a sufficient distance from the falling boxes, which often still 'roll' far. In order to avoid this, in a variant the ones placed on top of the stack are attached to their own box safety rope with a snap hook , so that when the stack collapses, the boxes slide down on the safety rope.
There is the variation of the 'double box' in which two box towers are stacked directly next to each other. Here the climber stands on the tower one box higher while the other tower is raised by two boxes. Then the climber (here more of a stair runner) changes the tower and the whole thing repeats itself. This makes it easier to reach great heights.
Crate climbing is better known for the ' Wetten, dass ..? 'Broadcast on October 8, 1988 where it appeared as a bet.
There are different intentions with which it is carried out: On the one hand there is the skill competition, whereby skill - or better the sense of balance - is in the foreground over the competition , since usually only one climbs and for most of them the challenge is their own record to improve. On the other hand, there is the overcoming of one's own fears, especially the fear of heights . There is also the group dynamic component, as the climber has to trust the belayer. In addition, the box-piling action represents a group process with corresponding learning success.
