SiChock is an industrial IoT solution designed to improve safety and efficiency at loading docks, one of the most critical and least digitized points in the logistics chain. The system is based on a connected smart wheel chock that detects in real time whether the truck is properly immobilized. Based on this information, it enables or conditions operations such as door opening or dock usage, preventing accidental movements and reducing occupational risks. In addition, it turns the dock into a source of operational data on loading start and end times, dwell times, number of operations, incidents, and misuse events.
