can anyone recommend me a high power actuator for either a horizontal or vertical crusher?
would an actuator like this be suitable?

they look to be ok although may be of poor build quality
True, I'm not sure on the quality but at 600kg it cant be that bad
At that kind o power the build quality can't be that bad
There's nothing to say that the figures that someone gives you on an ebay auction dictate the build quality of an item. Don't believe me? Go search for brushed speed controllers and see the crazy figures some people rate their speedos at (300A ish) when they would struggle with more than 5A.
You would be cheaper building a linear mechanism yourself. A couple of bearings supporting a threaded rod. The threaded rod coupled to a motor. A large nut or nuts on the rod attached to your mechanism will then do the movement. Simple and effective. Just make sure to grease up the rod (Rofl rofl rofl :rofl: )
I have a homemade linear you may of saw it at whitwick but this is it

its really for a vertical crusher or a more powerful horizontal one. what kind of power would a drill motor give?
i doubt you could get enough for an effective vertical crusher
then throw a speed 900 on the end or something even bigger. How do you think most linear actuators work? Threaded rod and nut style design.
I like the speed 900 with threaded rod on it idea :)
I cant find it now but i've seen a drill powered featherweight crusher.
Was great force from that drill motor, went through 8 or 10mm polycarbonate with ease etc.
You can get good power depending of course on what quality motor.
if you could find out that would be great since it sounds interesting too meQuote:

It all depends on gearratio and quality/shape of the treaded rod.
The higher the gearratio, the more torque is available, and the better the tread the better all works together. (trapezium tread with brass nut is the best between cost and useability. A normal tread and nut is cheapest, but the least efficient and easely damaged.)
