Telescopic bollards consist of a steel pontoon and bollard barrier with different diameters that can go in and out of each other. They work hydraulically and pneumatically. There is no electro-mechanical option in our barrier systems of this type. The production purpose of our telescopic mushroom bollard systems is that the excavation area is not deep enough. E.g ; 60 cm. If you are going to excavate at maximum depth . Our bollard barrier installed here is 100 cm. rises hydraulic piston and cylinder bollard has 2 stages. Telescopic bollard barrier systems are 100% domestic production and are under the guarantee of our company for 2 years. We have a 10-year spare part guarantee for our telescopic bollard barrier systems. Our telescopic automatic rising bollard barrier systems are produced in crash-tested and normal type mechanical parts. There is a crash test report. Our telescopic bollard barrier systems are divided into 2 in terms of the way they work. 1. Manually operated telescopic bollard barrier systems with lock and key, which can be manually lifted and lowered 2. Automatically working telescopic bollard barrier systems; remote control, wired button, license plate recognition, aags, RFID etc. Automatically operating telescopic cylindrical mushroom bollards are also divided into 2 parts in terms of working power supply. 1. Hydraulic (hydro-mechanical) automatic telescopic bollard barriers. 2. Pneumatic (air pressure) working automatic telescopic pontoon barrier systems. They are high security anti-terrorism and anti-ram bollard systems. It is in normal standard type productions and can be used in your garage entrances. They are ideally used in dimensions with low ground excavation (If the underground is a garage or if electricity, water, natural gas lines pass through the nearby ground, if the excavation opportunity is low and troublesome, etc.), choosing telescopic bollard barrier systems gives you great advantages. Our telescopic cylindrical pipes working by intertwining are manufactured from complete stainless steel, hot-dip galvanized coating on normal steel, and electro-static powder painted on steel. There is power illuminated lighting on the mushroom bollard that will make it easier to be seen at night. Provides manual use in case of power cut, opens the road to passage. OUR TELESCOPIC MUSHROOM BARRIER SYSTEMS are in their sets; 1. Used to prevent vehicle accidents. Photocell protection sensor, loop detector security sensor 2. Red-Green traffic light with pole 3. Remote control button and security bar fixed button with wire 4. Sound and light siren system 5. There are pole type phosphorescent warning signs. The rising telescopic steel pipe bollard part can be manufactured up to 1.20 meters high. Our 1.20 meters telescopic bollard barrier is only 70 cm. needs depth. This is the depth required for our 2-stage systems. In our 3-stage telescopic barriers, 120 cm. 45 cm for barrier height. depth is required. The bollard barrier can be manufactured from pipes of different diameters, which can be intertwined in 2 or 3 stages according to your height needs. As a system project and engineering company, Madoors offers manufacturing options according to your specifications and special requests. Telescopic automatic bollard barrier systems are our patented product. Please contact for information. General Features Telescopic bollard systems are produced as normal type and type with crash test certificate. Our crash-tested bollard systems can be produced in K4 / K8 / K12 / PAS68 standards. The report of each standard obtained from abroad is presented with the product . If you request these certificates, whose contents we cannot share due to security reasons, together with the price offer, we will be pleased to send them to you. Hydraulic and pneumatic type telescopic bollard barrier systems are manufactured in 3 parts. Outer body, inner slide body and movable part. The outer body is the part that is buried in the ground. The inner slide body is the part that enables the moving part to go up and down smoothly. The moving part is the part that rises and performs the main barrier function. Our K12/PAS 68 crash tested telescopic hydraulic bollards rise and fall completely in 1-2 seconds with the emergency start button in case of emergency. In this way, it instantly blocks attacks that can be made with vehicles and trucks loaded with bombs. The load resistance per single axle is 40 tons. Steel movable barrier body 10 mm. It is produced in wall thickness. The movable main body can be made of stainless steel cr-ni or steel drawn seamless pipe. This pipe is hot-dip galvanized and remains as clean as a stainless steel barrier for years. If desired, it can be manufactured from stainless (Cr-ni 316) chrome nickel steel. The photocell protection safety sensor is delivered in 2 sets, 1 meter apart, in front of the barrier axis and 1 meter behind it. The remote control receiving card is 2 channels. The remote control button is delivered with 2 pieces of 2 channels. In all our telescopic bollard systems, there is a photocell or loop detector application as a security measure. Our barrier systems are compatible with AAGS (under-vehicle imaging system), License Plate reading/recognition, Card reader and RFID system. The entire system works with dry contact information. There are power led lights on the pontoon. Our telescopic pontoon barriers can be manufactured in 2-3-4 stages. The main unit that provides operation has IP 65 standard and can be manufactured in a separate enclosure box or barrier body. Different color options are available for the barrier system. Thanks to the drain valve, the barrier can be manually opened in case of failure or power cut, thus allowing passage. Our bollard barrier systems are under our 2-year warranty. There is a 10-year spare part guarantee. It can be said that there is no risk of malfunction. In the unlikely event of a malfunction, the inner chamber can be pulled up from the ground-mounted outer chamber with a slide and the barrier can be used. In addition, the maintenance of the barrier is done quickly and easily in this way. Usage Areas At the entrances of the parking lot At the entrances of the private garages At the guardhouses of our military and security forces In the state institutions and organizations In the touristic streets and avenues where the vehicle entrance is wanted to be prevented As an anti-terrorist barrier at the entrances that require high security
