At last, a case is represented in order to demonstrate the use of the developed algorithm and to illustrate its essential features. The algorithm is incorporated into a three-dimensional 3D computer-aided system that integrates crane selection module, crane modeling module, 3D-simulation module, 3D computer-aided design modeling module, rigging calculation module, and data management module. This paper presents a newly developed algorithm for selecting mobile cranes on construction sites, which takes into account the lifting capacity, the geometrical characteristics of the crane, the dimensions of equipments and riggings, and the ground bearing pressure. It is a tedious job that lifting planners select cranes for construction projects based on a large number of lifting capacity charts. These charts are structured based on predetermined crane configurations, which consist of boom/jib length, lifting radius, main boom angle to ground, and jib angle to ground or its offset to its main boom centerline. No special expertise is required to use the program and apart from a standard PC, no additional hardware is required.Lifting capacity charts are tabulated and provided to operators and practitioners by mobile crane manufacturers. Map views from Google Maps and 3D data can be included in the display in the correct scale. The pro version contains detailed, interactive 3D models of the cranes, as well as a library with various 3D objects such as buildings, roads, machines or load objects. Each time the configuration, load or geometry is changed, a new calculation is carried out.Ĭhallenging planning tasks can be completed professionally in 2D using the free version. Key data such as ground pressures, support pressures, lifting capacities and centres of gravity are calculated simultaneously. The results of the planning process can be exported in the form of a report and sent to the customer. The tool combines an interactive 3D visualisation of the machines, the loads and surrounding objects with dimensions, a positioning tool and Google Maps, without the need for CAD programs or high performance computers.
This also includes the new distance tool, which enables objects such as machines and buildings to be positioned relative to each other with centimetre precision. Users of the current version will enjoy the benefit of the new crane models and functions, automatically and free of charge, following an update. The LTM 1350-6.1 will be the first of these. The new release features the following cranes: LTM 1650-8.1, LTM 1450-8.1, LTM 1300-6.2, LTM 1250-5.1 and LTM 1230-5.1.Īdditional telescopic mobile cranes are being added to the software at regular intervals. Liebherr has launched the latest version of its lift planning software, which now includes a variety of new cranes, as well as a new distance tool.Ĭrane Planner 2.0 is Liebherr’s lift planning and visualisation tool.
