A-Frames And Lifting Equipment

A-FRAMES
We have custom-designed and manufactured a wide range of A-Frames andlifting equipment devices for various industries and applications.

Depending on the customers requirements, such as operating in varioussea states, swell compensation, man riding units, retrieval of ROVsand lowering and raising of scientific instruments, different solutionsare available.

Units, if required, are designed and manufactured to class approval.

All cranes are protected for marine applications and are fully load tested in the factory.
Our Marine Cranes have a proven track record for their reliability and rugged construction.
