A new railway line has been provided with new safety for pedestrians, drivers and maintenance teams accessing electrical boxes, by Kee Klamp, guardrail fittings and BoxBolt fixing solutions.
Kee Systems provided safety products as part of the installation, forming part of an £89 million project to improve commuter times into London from Bicester and Oxford. Network Rail delivered the design and construction of the East West Railway route as part of a joint scheme with Carillion Plc and Buckingham Group.
Kee Systems worked in collaboration with Carillion Buckingham JV to supply 8,000 metres of Kee Klamp fittings and 10,000 units of BoxBolt to prevent pedestrians and vehicles from straying into off limit areas and to provide safe access for maintenance teams.
Network Rail’s design requirement for 1250mm high guardrail was met by Kee Systems products, achieving a 400 n/m design load for the project. Throughout the duration of the project, a variety of fixing methods were deployed, with majority being fixed using BoxBolt onto steel capping beams.
The project involved all the holes being drilled with a magnetic drill to fix BoxBolt and the installation of 56 units of Kee Klamp culvert headwalls, using a 114-8 off-set design to help accommodate the varying angles on each individual headwall.
Barry Mullen, Project Manager for Carillion buckingham JV explained that Kee Klamp fittings were chosen as they can be installed using a standard hex key, making it quick and easy to install.
The Kee Klamp has been designed with ease and speed of installation in mind, the components completely eliminate the need for hot works on site, offers cost and time saving as well as being very versatile and suited to a range of guardrail applications. It is manufactured from galvanised cast iron and securely joins structural steel tube into almost any conceivable configuration across a variety of angles.
In addition, Kee Klamp fittings can be installed using a standard hex key, with each fitting incorporating an internal set screw to lock the respective fitting safely and securely onto the tube. The Kee Klamp fittings are TUV certified for strength, manufacturing quality and consistency, complying with BS EN 1562 & BS EN 1563.
Where access is restricted or there are hollow sections, the BoxBolt range is the solution. The system is an economical solution to making blind connections when compared with traditional methods such as welding or bolting through. BoxBolt is a hexagonal head design that helps installation with a standard wrench, suitable for use with rectangular square and even circular hollow sections.
Three finishes are available for the range; zinc plates, hot dip galvanized and stainless steel. The system means no complicated fabrications such as welding internal nuts or providing internal stiffeners to reduce crushing from tightening. Lloyds Register and DIBt has approved the BoxBolt, and it complies with the design requirements to Euro code 3 and DIN 18800.
