Tower Crane Height Warning

The laser ranging sensor is a non-contact distance measurement method, which can measure the distance of the staff that cannot reach or some special places, and the measurement is convenient and safe. Laser ranging sensors are more reliable when taking crane measurements.
The laser ranging sensor accurately measures the target distance through laser, which has high accuracy, is very convenient to operate, and is easy to install. Therefore, the error of the crane girder span, the crane girder deflection and the diagonal line of the wheel, the vertical height of the crane to the ground , crane anti-collision and other aspects to measure and give early warning.
