Tensioning
Mechanical tension systems (compensation ratio 1/3, 1/4, 1/5) with concentric pulleys, fall arrest brake, and spring tensioners.
Our principle, OEM, offers various mechanical tension systems to address the elongation of contact and messenger wires caused by atmospheric temperature fluctuations. These systems are defined by their compensation ratio (1/3, 1/4, or 1/5) and type, including concentric pulleys, multiple pulley systems, or springs. They are tailored to specific characteristics such as the presence of brakes or structures for supporting and guiding counterweights. Our principle's offerings include: Concentric toothed pulleys with a counterweight fall arrest system for cable failure/cutting. Multiple pulley systems. Spring tensioners customized based on the section to be compensated and the mechanical tension of the cables.
