In most respects, the LoCo LCS units are standard load shackles and can be used as such. The essential difference lies in their special load-measuring pins, which are made from a special high-quality steel, and feature integrated active measuring system with sensory elements. These determine the forces applied by the suspended loads and transmit the data to electronic processors that are also integrated.
Depending upon the model, the rated loads range from 3.25 to 4.75 metric tons. Currently three models are available: LCS-AX - the simplest model, which is based on the LMS-M series with analogue signal transmission according to the industry standard (4-20 mA); LCS-DX - with digital and 4-20 mA analogue outputs and an integrated storage battery; LCS-RF - offering a choice of radio or digital cable operating modes as well as an integrated storage battery The transceiver radio module operates in the 868 MHz ISM band and is EU approved.
Thanks to their integrated storage batteries and Wake-On-Radio functionality, the DX and RF models can operate autonomously for up to 30 days. The test and calibration system featured by all versions has the advantage that the self-testing can be performed without detaching the load.
