Construction: Interference could undermine development of crane technology

Keith Armstrong, worldwide electromagnetic compatibility specialist at EMC Standards, looks at problems with electrical interference and how construction managers can minimise their risk

Cranes are synonymous with the idea of development. Typically used to construct buildings, cranes aid the economic and social development of a town or city. However, cranes suffer from a persistent problem that is indicative of a significant threat to the future of technology: interference.

In the early days of the UK Department of Trade and Industry’s EMC Awareness Campaign, there was an infamous incident where a man was crushed to death by a crane. In this case, electrical interference caused the crane to prematurely release its load while the man was operating it with his radio-control pendant. Unfortunately, this tragedy is not an isolated incident.

There was another incident with a company that claimed to have made the controls and drives for the first large scale hovercraft-testing tank in the late 1960s. It was, in effect, a sophisticated travelling overhead crane, which ran the length of a gantry along overhead rails and towed a hovercraft shape along a large pool of water in an even larger building. In those days, they used resistor-transistor logic, which ran on a 40 V rail to provide noise immunity.

Dassault Systèmes to acquire CST

Dassault Systèmes has entered into an agreement to acquire Computer Simulation Technology, a provider of electromagnetic and electronics simulation, for approximately €220 million. 

With the acquisition of CST, based near Frankfurt, Germany, Dassault Systèmes will complement its industry solution experiences for realistic multiphysics simulation on the 3DExperience platform with full spectrum electromagnetic simulation.

CST’s Studio Suite software is used by designers and engineers at more than 2,000 leading companies in the high-tech, transportation and mobility, aerospace and defense, and energy industries to evaluate all types of electromagnetic effects during every stage of electronic system design processes.  Continue reading Dassault Systèmes to acquire CST
