When the platform reaches upper limit, a limit switch is made. That switch fires the small double acting cylinder that pushes the steel pin into the deadbolt for safety... to hold platform in place in case of loss of air pressure. There is a button ("Unlock") that when pressed will unlock the...

I'm hoping to do this with just pneumatic device (No electrical devices)

Also... anyone know of decent free Pneumatic Circuit simulator software? Nothing elaborate. I just to want to be able to practice connecting diff types of valves.. and trigger outputs.

I have a machine that when operator presses button, it will move upwards. When it gets to the end position, a switch is made and that causes a double acting pneumatic cylinder to engage... pushing a pin into a sort of "Dead bolt" safety position.. to lock machine in place. Operator then does...

I have been told that plant air is 100psi.

I was thinking that cylinder could PUSH harder than PULL... And my original thought was to have the cylinders under the platformBut, space and ease of maintenance was an issue with that.So... I had to punt... And try something different.I've been told that plant pressure is 100psi.

Sorry about that. I do not know how to merge posts.

i am going to have 2 uprights. 2" x 2" tube steel... 3/16" thick walls. I'll add a bit of reinforcing to the bottom of ONE of the uprights. (I really can't add anything to the left of one of the uprights) I'm going to tie the 2 uprights together with a couple pieces of 2"x2"...

9.9 to 15.9...Are you saying that needs to be the length from the hinge to where the cylinder mounts to platform? (And, I guess thatd give the 45degree angle)

Absolutely!I'm using 2 - 2" bore cylinders. Is the stroke length long enough to get the ideal starting angle?(your sketch looks a bit better than mine... hah... Whatd you use?)

The cylinder is about 14" retracted ..and 22.5" extended.I wish it was that cool.. Hah

I feel that my best bet would be to mount the extended cylinder at a 45degree angle...and go with a longer stroke(Not sure how much longer) but, I'm not sure.

I'm making a device that will tilt a 500# load 20 degrees. Going to consist of a hinged 24" x 24" platform (that the load sets on). The platform will tilt to the right(clockwise) according to sketch. The upright post that the cylinder is attached to could be any length. The cylinder will...

I am hoping to build a 3 sides frame on heavy casters that could be pushed up to and around the drum.The 4th side would be a movable/removable gate.. that container a safety switch If gate is not in position, cylinder would not be allowed to engage.
