BOLLARDS

TESCON AG manufactures barrier bollards in a wide variety of configurations, such as retractable bollards for securing driveways and permanently installed fixed bollards for securing areas and property boundaries. As a standard, various bollard systems are combined to provide comprehensive protection:

Retractable bollards for installation in the entrance area

• Automatic bollards, hydraulically retractable (for busy driveways)
• Semi-automatic bollards with gas pressure spring (for sporadic use)
• Hydraulic bollards with hand pump operation (for sporadic use)
• Telescopic bollards with reduced installation depth, hydraulic (automatic or manual operation)

Stationary bollards for border and area protection

• Fixed bollards analogous to the installed retractable bollards
• Fixed bollards for shallow installation
• Removable fixed bollards

Mobile bollards as temporary barriers

• Blocking off access roads
• Guarding events

Look and appearance of the bollards

Our bollards are generally made of high-strength steel. The surface of the thick-walled tubes in particular is rough and is not suitable as a substrate for good corrosion protection. For this reason, the tubes are usually mechanically smoothed and then galvanized and painted in the desired RAL or DB color. However, the bollards can also be clad in stainless steel. Cladding with granite etc. is also possible. To improve visibility, the bollards can be supplied with LED illumination and reflective foil.

Attacks on people with vehicles and attempts to force their way into areas of critical infrastructure are becoming progressively more frequent.

Our ANTI-TERROR security bollards offer effective protection against such terrorist attacks. Especially in inner-city areas to protect pedestrian zones and catering areas, but also in public squares, parks and stadiums, the use of security bollards defuses danger spots.

The mere fact that an area or entrance is visibly secured with bollards usually means that potential offenders look for other targets!

Impact loads - Tested and "certified" safety

TESCON has carried out many crash tests at accredited test laboratories in order to test and prove the function and performance of the developed products both in practice and in an emergency.

The tests were carried out with 7.5 ton trucks at

• 48 km/h (667 kJ)
• 64 km/h (1185 kJ)
• 80 km/h (1852 kJ)

A test was carried out with a 30-ton truck at 80 km/h (7400 kJ). You can find the results here. A datasheet can be found here.

For the customer, the rating is critical. If the product receives a rating, the test is considered to have been successfully passed.

The findings and experience from these tests are used for the development and evaluation of product variants that deviate from the rated product, e.g. if the customer requires a different barrier height for design reasons or if the foundations need to be adapted to local conditions. The performance is then verified using finite element calculations.
