Development of an Integrated Toggle Jack for Lifting Automobiles

Abstract

In order to mitigate the problems associated with the use of a single jack and other lifting devices to raise cars completely off the ground to effect repairs, such as changing of tyres, maintenance of suspension system and intricate parts that are on and beneath the chassis, an integrated toggle jack was designed and fabricated for a load of 2.2tonnes. On performance evaluation it was able to raise cars of curb weights of 1.04, 1.24, 1.37, 1.48 and 1.58 tonnes to a height of 200mm in 1.1, 1.5, 1.2, 1.6 and 1.3minutes respectively.
