Sammanfattning: This Thesis is performed in cooperation with Kalmar Industries in Lidhult, Sweden. The projects main purpose was to develop a draft design of a test equipment. The equipment will simulate and valuate the drive-train and brakes at Kalmar’s bigger forklifts. The equipment will be designed so the wheels of the forklift are placed on two rollers; these absorb and affect the forklifts brake- and driving force. With this characteristic an up- and downhill can be simulated. Today, the forklifts are being tested on a test track. This test method is both very time consuming and the repeatability is miscellaneous with insecure values as result. The thesis has consisted of determining base dimensions like axle load, torque, power requirement, etc. Even roller, bearings and axle dimensions was created. Searching for proper application to drive and brake the rollers was also done. Under the project’s time mechanics- and strengths calculations were made. Even investigations of available and existing equipment have been done. The result of the project is proposition of a drive/brake equipment and a beginning of primary design.
