In this paper the design optimization of double box girder has been done and a comparative study of results of finite element analysis of a crane with 10 ton capacity and 12 m span length has been conducted. the design optimization of overhead eot crane . Thus a load which is slung above and through the center of gravity will be stable and will not tend to topple or slide out of the slings. j. adv. Figure 3-1 shows the assumed construction sequence. Performing Organization Code 7. Height of crane pivot point On standard tires, 100mm between ground and tires C. Sheaves distance For the Liebherr LTM 1100-5.2 the base dimensions are: A=2.0 m; B=3.83 m; C=1.1 m Calculations Minimum radius Minimum radius = ½*outrigger base Liebherr LTM1100-5.2: ½*7.0 = 3.5 m Maximum radius Pulley 4.

Deflection is the measurement for the displaced structural element under load. @Prolific 3D Tech presents Project which explains about How Crane Works? Using the crane with a broken cable can cause it to fail and drop the load. The girder box section is shown below: Figure-2 Crane Girder The rail must be situated directly over the inner web of the box girder, so that transverse flexural stresses in the top flange plate are avoided, as shown in Figure 12e. Boyd and foster method, also known as the semi-rational method can be used to find equal stress for ESWL (equivalent single wheel load). PGSuper models the various construction stages with … We are a small software development organization dedicated to develop computer software for design of EOT Cranes as per latest Indian Standards (807, 3177). Safety limit switches for stoppers will be provided to prevent over traveling in all motions. The vertical and horizontal displacement can cause changes in the design of the crane and also impact the working of the device. In the case of overhead cranes, displacement of any member or part of crane is considered as deflection. Use is made of a computer program to compare the behaviour of alternative girder support systems and the advantages and … Modular design, ease to install and maintain, reliable operation, fuse less circuitry, ducted wiring and compact terminals. Wheel Load Design Calculation of Jib, Double Girder, EOT Crane The crane wheel load, usually referred to as maximum wheel load is the total load in pounds that any single crane wheel will see. The calculation checks the design of simply supported gantry girders comprising of either a plain I section, an I section with a capping plate or an I section with a capping channel, carrying a conventional overhead or an underslung travelling crane. ...
