Measures the boom inclination above horizontal using "solid state" technology
- Installed on the side of the crane boom foot section, using two bolts only
- Measures the boom inclination above horizontal
- Using "solid state" technology without any moving parts for maintenance free, long service life
The sensor measures the boom angle. The hook radius displayed is based upon the crane boom length and geometry, calculated so the operator will have hook radius displayed in metres or feet.
The sensor is simple to install and is calibrated with using two known radii only.
