Hydraulic Ram

[frizzen]

The machine you referenced is called a 'Jackscrew mechanism'. You can use all-thread and nuts, or the nicer version uses Acme rod with Acme nuts.

Also a forum sponsor Actuonix makes several plug and play linear actuators, that can be run as either a linear servo that self centers or an actuator that holds position. It would be cheaper than hydro. They even have built in micro switches at travel limit.

Greg,

Here is a link to my dump truck video. I used a small motor to turn the threaded rod which turns inside a section of delrin that I threaded to match the rod.

Hi frizzen, thank you :-)
That's handy to know as I did look into some linear actuators some time back but at the time couldn't source one the right spec...I'll have to have a look at those if the hydraulic method doesn't work out.
All the best,
Greg
