LIDAR (Light Detection And Ranging, also LADAR) is an optical remote sensing technology that can measure the distance to, or other properties of, targets by illuminating the target with laser light and analyzing the backscattered light. LIDAR technology has applications in geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, remote sensing, atmospheric physics, airborne laser swath mapping (ALSM), laser altimetry, and contour mapping.This lidar (laser range finder) may be used to scan buildings, rock formations, etc., to produce a 3D model. The LIDAR can aim its laser beam in a wide range: its head rotates horizontally; a mirror tilts vertically. The laser beam is used to measure the distance to the first object on its path.
The Terex RH400 is the worlds largest hydraulic shovel and weighs nearly one thousand and eighy tons with a shovel capacity of ninety-four tons in a single scoop. It can fill huge mining trucks like the Komatsu 930E with three or four passes. The RH400 has the working ability to scoop up around nine thousand nine hundred tons of material ever hour which is a world record for a vehicle of this type
