Vertical Lift Check Valve

    vertical lift
  • A rare feature where instead of a lift hill, a coaster car/train is lifted vertically upwards on a section of track that acts as a lift. When this section is aligned with the rest of the circuit at the top, the car/train moves forwards to complete the ride.

  • A type of lift where the train rolls onto a section of track and is raised straight up.

  • Refers to a hardware design that causes doors to open vertically where no horizontal tracks are required





    check valve
  • A valve that closes to prevent backward flow of liquid

  • A valve which will allow water to pass in one direction but will close and prevent flow (backflow) in the opposite direction.

  • A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.

  • Limits the flow of gas to one direction only. Use a check valve between the bubbler and generator to prevent unwanted pressure build up in the generator, and a safety against a low level bubbler. A check valve, such as used on torches, is recommended.

Calumet River Railroad Vertical Lift Bridges
Pittsburgh, Fort Wayne & Chicago Railway Bridge

Construction Date: 1912-1913

The Lake Shore & Michigan Southern Railway’s two parallel vertical-lift spans over the Calumet River, and two neighboring spans built by the Pittsburgh, Fort Wayne & Chicago Railway (of which one survives), are the largest multiple installation of Waddell and Harrington’s patented design. Differences between the two pairs of bridges demonstrate disparity among American railroads’ building codes, as well as Waddell and Harrington’s refinement of the vertical-lift form. This site’s many bridges built in close proximity is an artifact of intense competition among trunk lines entering Chicago from the east, and perhaps the greatest physical monument to the railroad capital of North America.

Vertical lift shuttles allow storage of parts all the way to the ceiling. Automation of parts retrieval reduces time and labor that are required for a traditional warehouse.
