A-Frames for Offshore Use

Hi

I'm searching for manufacturers of A-frames for offshore use. I have following info:

- Distance from foot hinge axis to load attachment in top of A-frame 50 metres

- Load 30 Tm x 3 (all together 90 metric tons)

- A-frame angle at parked position 3 deg. from vertical

- A-frame angle in operational position 26 deg above horizontal

Regards
