Telescopic Strut.
Telescopic Strut.
(OP)
I am looking for a telescopic strut for a marine application (think camera tripod or monopod). I need it to collapse to 800mm or less and extend to 1800mm. Max load is 100 kg axial. Problem with available tripods they all seem to have friction locking only. I need positive locking (pins perhaps?) but without backlash (so it needs friction or clamping as well).
The strut will act as one leg of a tripod for towing a sub-surface apparatus. Depth of the apparatus will vary from 600 mm to completely out of the water.
Alternatively a linear actuator (either 12v or manual) that meets the above specs might do the job.

Then you could adjust it and and it would stay in place. You could motorize it if you wanted to.

If you absolutely require a reliable friction clamp, you don't need the positive lock, except perhaps as a fail safe device.
Could you use a hydraulic or pneumatic ram extended to solid height?

You are judged not by what you know, but by what you can do.

Greg, I forgot to mention. Length needs to be adjustable in increments of 100mm (4") or less.
