Removable Bollard Sleeve – You Might Have Been Curious About Why You Will Want This..

Bollards are used in a number of applications, for one of various purposes. One needs just to keep a sharp eye to see bollards around us every day. In parking lots, driveways, and drive-thru lanes, bollards are utilized to protect buildings, teller machines, utilities such as gas meters, electrical equipment and fire hydrants, handicap parking signs, gate entry keypads, and to restrict access to undesired areas. In factories and warehouses, bollards are important for protecting pedestrians in addition to guarding storage racks and capital equipment from fork truck collisions.

Other industries which look for a heavy usage of safety bollards include automated car wash facilities, self-storage facilities, service stations and convenience stores, propane dispensing, and parking garages, amongst others.

Foundation mounted bollards are usually installed in certainly one of two ways. The initial, least expensive way, is by using a plate mounted bollard. These bollards are steel pipes welded to some flat steel plate that can be anchored to your hard surface using concrete anchors. This method of installation is quick and inexpensive, requiring the installer to drill four to eight holes within the concrete and bolt down the bollard with expansion or screw anchors.

The down-side to this particular installation method, when used with a rigid bollard, would be that the anchors are typically not sufficiently strong enough to resist anything more than a minor collision. The plate anchors often are pulled up and perhaps the plate bends, leaving a post which leans and has stopped being in a position to properly serve its purpose. Plate mounted bollards often require constant maintenance and replacement.

The 2nd method for installing bollards involves using a longer steel pipe and burying a portion from it deep in the earth. This process gives the bollard a lot more strength than surface mounted, however it may be extremely expensive to put in in the event the surface is concrete and already poured. Installation in this instance requires coring a hole inside the surface employing an expensive diamond bladed coring saw. These machines and their blades are expensive and require water cooling, developing a mess during installation. When the concrete is cored and the bollard is within place, the hole should be backfilled with concrete to secure the bollard. For additional strength, these bollards are often loaded with concrete, as well. Even though the bollard pipe itself is relatively inexpensive, this installation strategy is costly and time-consuming.

Although very strong, you will find significant disadvantages to core installations. Most importantly, there is not any share with this method upon impact. Though desired in high security applications, any vehicle impacting such a bollard is going to be significantly damaged as well as its passengers in danger of injury. Loads carried by fork trucks can also be thrown due to the jarring impact very likely to occur. Further, the bollard or its foundation may be damaged by this type of impact, again leaving a tilted and fewer effective barrier requiring costly maintenance to improve. Frequently the steel bollard itself is beyond repair and must be replaced with the entirely new bollard.

Another downside of this kind of installation is it is actually a permanent installation with little flexibility for movement. In factory applications, equipment is often moved and rearranged. Bollards used to protect equipment or storage racks which can be core-installed are not easily moved. The concrete all around the bollard must be broken out and also the large remaining hole filled, leaving a factory floor packed with unsightly patches. In the event the bollard is reusable after removal, the complete expensive installation process is started over at the new location.

Some designs have already been created to attempt to solve these problems with the use of plastic or spring loaded bollards, however these designs suffer from a lack of strength. When the plastic is of insufficient stiffness, the entire function of access denial is lost. On the contrary, very stiff plastic designs have had difficulty with long lasting durability. Minor collisions have a tendency to wear away at such devices, and then in outdoor applications UV degradation gets to be a concern.

Designed and patented in Europe by Belgian inventor Gerard Wolters is actually a unique system which solves most of the problems associated with traditional foundation mounted bollards. In other words, the device utilizes a compressed rubber base to behave as being an energy absorbing mass. This elastomer allows the bollard to tilt slightly when impacted, in the plethora of 20 degrees from vertical, then return upright while still stopping the colliding vehicle.

This method is mounted on concrete using concrete anchor screws. These anchors affix the base component within the adapter, which pre-compresses the elastomer up against the ground. The base and adapter pieces are created from a special ductile cast iron, which makes the pieces less brittle than typical cast iron, and also has a really low (-40 degrees) brittleness temperature. The steel pipe which functions as the bollard post is actually a typical steel pipe inserted in to the adapter. Standard pipe is utilized to give the conclusion user the flexibleness to weld fencing using standard components if necessary. Concrete fill is not required inside the bollard pipe, though is permitted. In reality, sign posts can be inserted into the post and concrete completed place.

Upon collision, the pipe and adapter are permitted to tilt within the base, forcing the adapter to help compress the elastomer in the direction of the impact. The elastomer absorbs most of the energy of the impact and lengthens the deceleration time of the vehicle. The elastomer is of sufficient strength to then rebound, usually pushing the car away from the bollard and going back to a vertical position. The tilt of the pipe has limitations to approximately 20 degrees after which the bollard can become rigid.

Bollards are designed in a number of sizes, all of which can be right for various expected collision speeds and masses. Further, modular connectors which may be used to create fencing and guards from multiple base units happen to be developed to eliminate welding. By making use of multiple base units, the best strength of the rebounding bollard unit may be increased.

These new bollards utilize the much simpler method of surface installation, greatly reducing installation costs, while keeping the flexibility to go bollards as conditions warrant. This can be accomplished with no normal downside of absence of strength, because the elastomer within the bollard system greatly decreases the maximum impact forces applied to the base anchors. This is because deceleration of an impacting vehicle is much less severe than throughout an impact having a rigid bollard. Energy is moved to the elastomer as opposed to directly to a rigid post, lowering the harsh impact of a relatively immovable object.

This leads straight to the most important advantages of the new bollard system and that is certainly the reduction of damage to both offending vehicles as well as the bollard system itself. Direct damage to vehicles is reduced due to the reduction of peak impact force seen through the vehicle. This will not only avoid damage to the vehicle, but the chance of trouble for a passenger is likewise reduced. With regards to a fork lift in a factory or warehouse, the risk of a thrown load is also reduced, avoiding the potential for bystander injury and stock loss.

Finally, damage to the bollard and its foundation is reduced. As the post is constructed of strong steel pipe, it maintains its strength, but due to its forgiving nature, significantly less force is moved to the building blocks. This simplifies and eliminates maintenance while preserving an aesthetically pleasing facility.

These bollards has to be installed on concrete, as an asphalt surface is not of adequate strength to anchor the bollard system. Taking into consideration the replacement costs of damaged bollards, however, it could be cost effective to pour a concrete pad and eliminate many years of costly maintenance and asphalt repair. As earlier mentioned, each bollard is sized for expected loads when it comes to mass and speed. Should that limitation be exceeded, it really is easy to break a component of the device. Most likely which involves the post, adapter, or base. Fortunately, the device is modular and easily repaired. Posts can be replaced by loosening several set-screws, wwbpkl and replacing, and re-tightening the set screws. Adapter and Base components can be replaced by carefully removing the concrete screw anchors and replacing the component.

The SlowStop Bollard method is a revolutionary new product which solves most of the problems involved with bollard collisions as well as installation and maintenance issues. Harm to vehicles, passengers, vehicle loads, and also the removable bollard sleeve themselves is reduced as a result of absorption of impact energy by an elastomer hidden in the bottom of the bollard. This elastomer allows the bollard to tilt when impacted and return upright afterward. SlowStop Bollards are fast and inexpensive to put in, flexible because they are easily moved, and uncomplicated to maintain if there is the necessity. Safety fencing and barriers are often created using modular connectors, avoiding the necessity to weld pipe together.
