To be able to do measurements, for example, in cable pulleys, force measuring pins need a constant looping of the cable so that the direction of force transmission of the resulting force remains constant. The looping must often be held constant during various boom positions with the aid of an auxiliary roller in the crane boom.
BROSA has developed a force measuring pin which can output the line pull to the PLC regardless of the looping of the cable pulley, also varying within a defined angular range.
When measuring in the foremost cable pulley on the crane boom, it is possible to minimise friction losses, the construction effort as well as cable wear and use of materials.
As a proven means to detect forces in eye-bolt connections, the force measuring pin can, using new technologies, open up new application fields and solve measurement tasks that were previously only mastered with more complex concepts. The additional features described in this article were also used in BROSA tubular load cells (patented sensor design) and offer additional constructive advantages.
The increased versatility of the force measuring pin which results from the additional functions, certainly offers even more options for arranging the crane operation more safely and efficiently through innovative ideas. BROSA, with long years of experience, is happy to be at your disposal as a development partner.
