The adverse effects of neglecting to obstruct a vehicle’s motion during maintenance operations, such as tire changes or suspension work, can lead to severe hazards and equipment damage. Hence, developing an appropriate technology for a vehicle wedge is essential for ensuring vehicular stability during such operations. This paper presents the design and construction of a low-cost, mechanically simple vehicle wedge capable of providing motion obstruction during the lifting of any vehicle suspension point up to 160 mm height for passenger cars weighing a maximum of 1660 kg. The design calculations cover the evaluation of ground clearance of common passenger cars in Nigeria, curb and maximum vehicle weights, applied load on the wedge, frictional forces, and the critical buckling load of the wedge plate. The fabricated wedge was tested on selected passenger cars and demonstrated excellent motion obstruction during lifting. The design proved both technically sound and economically feasible for local automotive applications.
