Instruments

Benthic elevator

Supplied Name: McClain benthic elevator

Supplied Description:

Elevator used was a aluminum work basket suspended from the vessel’s winch. The elevator was special build for PI McClain by Theriot Machine Works (Chauvin, LA). The basket is rectangular in shape with an A-frame frame pick point and 2 independent doors on either side of A-frame. Total length is 1.96 meters, width of basket is 1.33 meters and height of basket enclosure is 0.96 meters. Maximum height at pick point is 1.85 meters. The basket lids on either side of the a-frame swivel on dual hinges and open fully to touch the a-frame where they are held in place by attached magnetic strips. Each lid has a width of 1.25 meters and a depth of 0.765 meters.

Instrument Type

Generic Name: Benthic elevator

Generic Description:

A platform used to carry equipment and samples from the surface to the seafloor and back up again.
