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.
