Construction of ball connector for Huddig : Construction of ball connector for Huddig 1260 backhoe

This report describes the construction of a ball connection structure with ball hitch to Huddig AB Backhoe, 1260. As will be used to pull heavy trailers at work. The reason for the project is that people often tend to make their own solutions to this problem, which is often made using modifications of the rear frame, where laws and regulations are unclear on what is legal and what is not. In this report. The laws and regulations will be examined, to see what actually comes to the construction of towing devices for backhoe loaders. These laws will then be the basis for the construction. A prototype construction will be made in SolidWorks and then calculate the strength through finite element analysis to ensure that the construction has good strength. As well as a choice of ball hitch from other manufacturers will be investigated. The construction is made to withstand 15 ton traction and 3 tons vertical load on the towing ball. The structure must use existing anchor points on the machine where normally the train set is mounted on the "rail" models, and where a tow hook is mounted on the standard models. This report addresses only the construction and not the prototype manufacturing process. The idea is that it will later be included a hydraulic design to open and close the ball connector.
