BERGHAUSNEWS Issue 61 ⋅ September / October 2019 berghaus-verkehrstechnik.de Dear Readers, ProTec 121: On-top fence, and visual screen and security element Tested to DIN EN 1317! Since the presentation of our products and services at the DeuSat in March 2019, we have been working at a few new developments that we would like to introduce in this issue. Fully in line with our motto „We want you to get there safely“, all products have been tested thoroughly and certified accordingly. Our comprehensive range ensures that construction sites such as the Elbe Tunnel or major events such as the Hessian Day run smoothly. AVS also continues to grow on the international scale. Dirk Schönauer has been appointed to the management team at Peter Berghaus GmbH to let everyone benefit from our long-standing know-how, also internationally speaking. We hope you enjoy reading this issue of Berghaus News and that you have a successful construction site season! Dieter Berghaus, Managing Director The mobile crash barriers in the proven ProTec family can now be supplemented with a new on-top fence together with a visual screen and security element for ProTec 121. Following successful tests of other additional elements for our ProTec crash barriers in 2018, such as the emergency opening ProTec-Tor 120, these successfully tested new developments are ideal extensions to the existing system. ProTec 121 on-top fence In spring 2019, the on-top fence was successfully tested in combination with our ProTec 121 for containment level T3 with a truck and a car according to the test criteria and requirements of DIN EN 1317. The on-top fence comes with reach-through protector and square mesh openings. It is fastened to the restraint system on the working zone side. The fence is fitted with a non-transparent net that acts as visual screen to let the wind through. The structure is fastened to the ProTec 121 with a forcefit connection consisting of a specially developed bracket. The complete structure consisting of ProTec 121 and on-top fence is 1.50 m high. ProTec 121 visual screen and security element The series is rounded off by another new development consisting of visual screen and security element. It provides construction site workers with effective protection from grit, flying stones or spray caused by passing traffic. Furthermore, the flow of traffic is not distracted by the work taking place behind the visual screen. In another impact series which was again carried out with our mobile crash barrier ProTec 121, the visual screen and security element with a total height of 1.15 m was successfully tested for containment level T3 according to the stipulations of DIN EN 1317. In 2016, the mobile crash barrier ProTec 121 with a structural width of just 24 cm was developed and tested by our steelwork department and classified by the BASt (Federal Highway Research Institute) with BASt test number 2017 7E 60 as crash barrier with containment level T3 and the lowest effective range W1, and approved for use as construction site protection according to TL Mobile Road Restraint Systems. The new, tested components consisting of the on-top fence as well as the visual screen and security element make a perfect addition to the system. 2 Mobile mast for traffic lights and overhead cabling 3 • DeuSat 2019: review • IRF – Better roads. Better worlds. • Additional module for AmpelTools Mobile masts are indispensable for setting up temporary traffic lights at major crossroads. They act as sturdy traffic light masts for high signals, and also for fitting overhead signals depending on the version. They also allow for safe overhead cabling well above the reach of pedestrians or vehicles. According to the Technical Delivery Conditions for Mobile Traffic Light Systems (TL-LSA), overhead cabling must have vertical clearance of at least 5 m for 50 volt and at least 6 m for higher voltages such as 230 V mains voltage. Now up to 7.90 m high! 4 • Mobile warning trailer SM 10 • Barrier system with traffic light • Hessian Day 2019 • Major construction site Elbe Tunnel • AVS International The mobile rotating and tilting mast by Berghaus permits fast, stable installation of a robust traffic-light signal mast with high signals. It is possible to attach a crossbeam measuring 4 or 6 m in length from our range of accessories as a projecting arm for positioning signal heads directly over specific lanes, also for lane signalling. The new add-on element considerably extends the previous socket mast height of 6 metres and allows overhead cabling at up to 7.90 m in height. This is ideal for taking cables above the overhead contact lines for tramways. The rotating and tilting mast is quick and easy to install for the various usages. It needs space of just 1.20 x 1.20 m to stand on; the base with fitted bottom section is only approx. 2 m high. This mobile socket mast system is very popular because it manages without a concrete pedestal that could easily weigh several tons. If necessary, it can even be set up by hand. Depending on the specific usage, it is weighted with up to 32 commercially available K1 base plates that are placed in the corresponding holders of the base, also acting as theft protection. Lift trucks, forklifts or loading cranes can also be used for installation, depending on the available space. Structural calculations are available for many applications, including for installation of temporary traffic-light masts and high signals in different quantities and heights, with or without side projecting arm and for overhead cables at large heights and over wide distances. The rotating and tilting mast is also ideal as a robust mast for our height warning system or as a light mast for large-scale illumination.
