SYIL Power Drawbar

Fantastic! :D I am as it goes

Is it any old butterfly wrentch or a specific brand/type?

• Standard old butterfly. You have space & might want to beef up the air piston from the small one I have.
• Find a 12 point socket for the drawbar.
• Air plumbing (in my case) used 3 air solenoids.
• The long strip in the design suits a limit switch to start the wrench.
• Cut an internal relief for the piston clamp
• Source a couple of linear bearings for the wrench plate travel
• The bars were silver steel (what I had in stock at the time), they're holding up fine.

Thats very good of you. thank you :) couldnt understand what you meant then for a sec - so a roller type limit switch will start the wrentch as the piston ends it stroke ? I pretty sure ive got it.
