The Platform Elevator provides a large cargo area for transporting experiments to the seafloor. The floatation can be adjusted for payload. However, the large surface area can also be affected by strong currents.
Total in-air weight limit is 2500 pounds.
Use the payload worksheet to determine elevator weights.
With 16 cu ft of syntactic foam, the elevator has an in-air weight of -915.8 pounds without any payload. The addition of the required anchor (-375# air) brings that total to -1290# in air. The addition of 1200# of payload brings the in-air total weight very close to the 2500# limit.In water, the empty elevator has approximately +281.65 pounds of lift. A 375# in-air (steel) / (326.25# in water) anchor will provide -44.6# net weight to keep the elevator on the bottom. The addition of -250# in-water weight of payload will leave + 31.65# of lift to bring the elevator back to the surface once the anchor is released. This is a minimal amount of lift and may lengthen the time for the elevator to reach the surface.
