Gripper utilities - line cutters


(Oystein Skarholm) #1

Any clever and handy persons out there who have made tooling to replace the claw yet? Like line-cutter or any other smart and handy add-ons?


#2

Not really tooling but this might give some ideas… https://discuss.bluerobotics.com/t/attaching-a-carabiner-to-a-rope/4092

i have the plan, but havent done anything yet, looks like we can copy the “originals” with this… make the piston drive the cutter, so its a mecanical thing. …but i had oxyarc in my mind the other day for cutting, can cut whtever we want in the end there, one string is enough for a lot of steel :wink: …but you need the oxy to…?..might go with a ponybottle… a thought towards the problem that comes :wink: …the way of ROV…

…but the coolest way…a mini grinder/cutter :wink: …but also…diamond wire… roll and cut?..truster motor can do it?

OXY ARC needs quite some O2, a pony bottle wont bring you far. Cutting a wire or a chain may be feasible but I doubt you will be able to perform a nice cut of any length.

a Pony will bring you One string… as you have the abillity with a Bluerov2, l´ve been using oxyarc so i know the amount of oxy, the amount of cutting is beyond every battery you must use of Any cutting in difference of One string of Magnesium, it will cut about a 10 cm chain(if you can use it)… i know i have done it. if you need a bigger bottle or surfaced oxy?..so what?..can cut Everything exept Wood! ;)…easy to implement…to start it, use battery?.. simple;)…And no fingers are gone after work :wink:

…cutting is cutting…how it looks?..who cares?..haven gotten any complains yet after +10 yrs in the in the industry, get i Loose!..thats the task. if you need a Good looking cut…call DO( in Hgs.) ill do it :wink:


(Oystein Skarholm) #9

Have you tried cutting with oxyarc attached to an ROV? Even though I love the idea I am bit skeptic as you will loose the “feeling” I have been doing my share of oxyarc too after being a diver for 30years :wink: Do you work for DO ?


(Christian) #10

Nope havent tryed cutting with a ROV. but i see that it shuldnt be a biig problem… practice, but when you have it?.. se my point?:wink: ( but in my mindttravel in this idea… diamond cutter… thats easy… just need a motor and the wire going around?..can curt allmost anything? …but i dont see the big issue by cutting with oxy, just ned a manip to control your angles;) been in most but, DOF,Do, Oceaneering is primary, and IMC in Bergen…( the setup at Helge Ingstad is me who made)… got my Traninee time at Geoconsult :wink: …i built Geomasters windows on the bridge when i was 13 ;)( so iva been in the industry for a while;) …and IKM, no comment…spyr. :wink:
