Crane Height Limitation Management System GPSkySafety (Land)

basic information

【System Overview】 It automatically calculates the distance between the GNSS antenna position installed at the tip of the construction crane and the set restriction surface in real-time. If known points are available, a GNSS base station is set up to transmit correction signals via radio. In environments where a base station cannot be prepared, network-based RTK-GNSS surveying can be performed using VRS (Virtual Reference Station). Height and position accuracy can be managed within approximately 5 to 6 cm. Current altitude is visually displayed using dedicated PC software. Workers operate the boom based on the height/clearance display on the screen. When the boom tip approaches the height restriction surface, an alert is triggered through audio and screen display, providing a warning to both the workers and supervisors.
