Bollard

As bollards are mounted in vertical soil piles called.

Shipping

In shipping, a bollard is a post made of metal or wood for mooring a ship. On the land side, on the quay or at the pier bollards are usually cast fungus- or hook-shaped ( → figure) metal body, about which the Schiffsbefestiger sets the mooring line. Board side bollards are usually designed as a welded construction, fitted up with a cast or welded thickeners and in pairs. An on-board Double Bollard not only serves to prove the mooring line ( eight shaped herumzuwickeln ), but can also be used as a brake to fully decelerate the ship with the very first mooring line, for example, the Vorspring. To this end it is occupied with only a few trips ( turns), and with the loose end is yielded soulful by hand so that the mooring rope slips to break instead ( tear ). This is called schricken or veer. For mooring ropes thinner serve the cleats on board. As such there needs at least one latching, the reliable jammed the loose end of the rope and yet can be easily solved. (see also: rope friction)

Road

The road is called a bollard or post small pillars made ​​of metal, wood or concrete. They are installed to prevent the driving or Beparken of areas such as sidewalks, bike paths or pedestrian areas. To allow a temporary passage to the example of fire-fighting operations, folding bollards or plug bollards are used, which can be operated with a special key. A special form of bollards are the so -called concrete pigs that vaguely due to its shape to a pig. In the Westphalian space these bollards are also referred to as Pömpel or in some areas as a stopper, in Amsterdam they are called Amsterdammertje.

There are also automatic retractable bollards, for example, to release a guideway for buses regularly in a Busschleuse to terminate for private but. Here, the bus sends a signal to the plant, after which the bollard to retract automatically and opens the way for the bus free by radio. In spurious pedestrian zones they are the same system also increasingly being used to enable the delivery traffic to shops and the access of residents to their land. This automatic retractable bollards are marked with signs and may have a traffic light.

Instead of a vertical game space have so-called flexible bollards (also Kickback bollard ) over a horizontal tilt angle, usually up to 45 °. These can be made ​​of hard rubber or, as the rigid bollards are also made of stainless steel, but will have a contact with a motor vehicle, reducing harm from. Flexible bollards have an ankle which deflects impacting forces. If there is a contact of a vehicle or a person who gives way to the bollards back in the opposite direction of the force and depends on automatically returns to the initial state. Used this type of "intelligent" systems limit both on the road as well as in industrial halls.

Recently, it has Hutpoller developed and placed on sidewalks along the roadside. They can be used for temporarily sitting on stools and how should people with walking difficulties give opportunities to rest.
