Adjustable Tie Backs
Adjustable Tie Backs
(OP)
I have a little job at the moment to design a small tied back 'A' frame to support a snatch block. Nothing difficult about it except the client wants the tie back members to be adjustable so they can change the 'A' frame angle to horizontal on site. This is because the frame has a restricted clear height and the client wants to reduce the risk of it not fitting.
The frame will be used on platform topside so hot work is not permitted.
I was thinking about using screw jacks for the two tieback members but have been unable to source something suitable. The loads are pretty low.
Could any members offer up some suggestions?

if the frame is to heavy for a man to hold while adjusting then you can add a small block&tackle to support and move the frame while the pins are out for adjustments
or you could just use a chain fault with a lock for a tie back that would support and adjust all in one

I have used the two sliding member arrangement before, and it worked fine, but it was on a much smaller member. These will be over 6m in length and from a health and safety point of view I would like to have them self supporting.
