A Jack is a device which can lift heavy loads with an application of a small force. This scheme is followed to lift cars with the help of car jacks. Hydraulic powered jacks are more influential than other jacks. The present work is focused on the design and modification in the existing model of trolley jack 20261. The former model was carefully studied in terms of the design features, specifications, capacity and with the help of new methodology an attempt was made to fabricate a new design that can produce greater capacity within the economic range. The work consists of the fabrication of the new model and projects the advantages of the new design. The new design was successfully made and was able to fulfill all the required objectives. The following work can be a new eye opener for the design engineers dealing with design of jacks.
