Abstract:
1. A method of monitoring crane safety during the setup procedure of a crane, comprising the steps of providing the crane with a sensor system and a crane control, assembling the crane from a transport state into a working state including luffing up a boom of the crane, as the crane is being assembled and the boom luffed up, prior to the crane being in a payload table applicable to usage, sensing at least one angular position of components being raised or assembled by the sensor system as one or more measured values, directing the one or more measured values to the crane control which receives the one or more measured values from the sensor system during the setup procedure, comparing the measured value or values received by the crane control with at least one corresponding angle-related limit value, and triggering a response on exceeding and/or falling below the limit value.
