Hydraulic Tools and Equipment for Underwater Salvage

摘要

Commercially available hydraulic pumps, rigging, load handling and cutting equipment have been evaluated to determine characteristic diver performance and mechanical suitability for underwater operation. Manually operated hydraulic pumps were modified and pumped against a load cell to determine reasonable levels of diver exertion. Tests have shown that divers can be utilized as prime movers for small jobs and that some conventional surface hydraulic equipment can be used underwater for reasonable periods of time with a minimum of additional maintenance. Surface hydraulic equipment suitable for underwater operation includes manual pumps, rams, cylinders and several cutters. (Author)
