Generally speaking, there are three main types of ramps as well as variations or hybrids of the three spiral ramps, switchback ramps and straight ramps. Each has advantages and disadvantages. Placement will also play a large role in determining what type of ramp is best suited to a project, therefore these design parameters should be established in tandem.
