Selecting the proper length and type yard ramp is the third characteristic that should be determined. The straight type, which is 30 feet long, is used primarily for ground to dock applications. This is a good choice when no level off is required. The level off type, which is 36 feet long, is used in most applications. The six foot level off at the end of the ramp adds maneuverability for forklifts. This allows forklifts easier turning access into rail cars and allows them to handle pallets next to the door openings. The 36 foot ramp is the most popular where end loading is required. Level off type is noted by the letter L following the model number.
