EzyCalculator is an interactive online tool designed to help you calculate safe loads to spans for steel, aluminium and FRP strut and cable support components. When developing our cable support OBO can offer reliable solutions for systems, three attributes are at the routing and fastening cables securely core of what we do: efficiency, resil- for each of these installation challeng-ience and safety. Cable ladder systems and cable tray systems shall be manufactured in accordance with BS EN 61537, channel support. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support. Seismic Category II cable trays and their supports are also designed utilizing the design criteria of this appendix.

EzyCalculator is an interactive online tool designed to help you calculate safe loads to spans for steel, aluminium and FRP strut and cable support components.
A cable support system consists of cable support lengths and system components, such as cable support fittings, support elements, mounting elements and system acces-sories. The cable support
This standard defines configurations for the mechanical tests to be performed on cable trays, brackets, hangers and other accessories. It also specifies the requirements and methods for the electrical
Abstract In order to realize the optimal design of the cable supporting system for the purpose of material saving and energy saving and green manufacturing, the strength-stiffness ratio is
For flexible systems, where the cable is not directly fixed to the support system, for example a J hanger installation, calculations need to be undertaken to determine the required distance between the cable
A cable tray hanger is classified as a _ seismic Category I structure, and therefore, it shall be adequately designed for the effect of the postulated seismic event combined with other applicable and''
- Calculations are provided to check bending stress, shear stress, deflection, buckling, and forces on supports to ensure the design is safe based on the
The radius for cable ladder and cable tray fittings is usually determined by the bending radius and stiffness of the cables installed on the cable ladder or cable tray.
The document then covers structural design stresses and factors of safety used in determining allowable stresses for aluminum alloys and hot rolled steels. Finally,
