When I bought a used passengervehicle and started it, my first mate at the garage has become… the lift that I built the ceiling. Without him I would hardly be able to, for example, such difficult alone operation as engine replacement.
Infigure 1 shows the location of the lift in the garage — just above the hood of the car. With a boom length of a little more than a meter, my tap has a working area of approx 5m2. This is enough for maintenance or repair of the vehicle to remove and return in place of heavy components and assemblies.
