When planning a lift, LiftPlanner and Lift Movie developer, Jim Meehan says, “Site information is provided from one of three sources: a computerised plot plan of the lift site is available from the construction company; the lift planner has to visit the site to take precise field measurements; or a three dimensional laser camera can be used to create a dense grid of spatially-aligned points, known as a “point cloud”. The point cloud measurements taken around the site are joined together, transferred into AutoCAD and the cranes, rigging and loads inserted to produce a view.
The project (left) is a malting plant in Minnesota, which was scanned by LiftPlanner Software in conjunction with Online Systems Inc. A Liebherr LTM 1220-5.1 wheeled mobile with 60 m main boom and a 22 m fixed jib offset at 30 degrees was used to place a baghouse on a 61 m high silo platform.
The information gathered by the laser scanner can also be used to create a video of the complete lift, using LiftPlanner Software’s Lift Movie program.
