Siko has developed a range of wire-actuated encoders for a wide spectrum of applications with measurement lengths ranging from 600 mm to 40 m. The functional principle is simple. A measurement wire is wound onto a drum and when the wire is pulled out, it causes the drum to rotate. A sensor connected to the drum axle records this rotation and generates a measurement signal proportional to the wire movement of the drum, which indicates the position.
When extending crane arms, exact position detection of the supports is essential in order to prevent the crane or truck from tilting or toppling over. This is done by measuring the current values of the extended supports and comparing them directly with the length of the extended crane arm. This means that complete extension of the crane arm is only possible if the supports are also extended to the maximum width.
Lifting platforms
Wire-actuated encoders are not only used for cranes operating at great heights. Optimum precision is also needed when extra-long loads have to be lifted. Wire-actuated encoders ensure even lifting e.g. of trains, underground trains or trams using a lifting platform. Failure to observe this can cause strain, which can result in damage to the entire construction.
Space-saving and resistant to cold
A redundant system is often necessary for safety reasons and in space-constrained situations. With these precision requirements in mind, Siko has developed the SG 30 wire-actuated encoder with its particularly slim, compact design. Despite its space-saving size and lightweight of approx. 500 grams, no compromises have been made with regard to stability. The outer housing is made of sturdy zinc die-casting and the spring housing of fibreglass-reinforced plastic.
Another unique feature of the SG 30 is its wide range of working-temperatures, which enables it to be used from -40 to 80°C. Four lockable aeration holes are integrated to avoid condensation. The wire outlet has a special protective seal. The wire pullout is flexible, so that 100% alignment with the extension direction of the outlet is not necessary.
