ganging linear actuators 1

[MHED58]

Does anyone have any advice on ganging linear actuators?
I need to lift 2000 lbs. I have 4 posts like a table.

I want to replace a hydraulic lift table with screw jacks in order to open up the area under the table.

Screw jacks require guides like profile or round rails, while actuators have this feature combined.

Linear actuators even have the motor built in, but since my table is 80 x 30 inches wide, at least two maybe 4 actuators may be required.

Thanks for any advice

3 points fully define a plane. 4 are statically indeterminate.

You can't count on people always placing the CG of the load exactly on the effective force center.

Thanks Mike
My loads and requirements are similar to the posted link.
This is also why I try to stay away from chains.
I find Jack screws work better in tension, but to build a frame to hang from cost money. A profile guide way will prevent some of the splaying that Itsmoked saw on his chains.
Also under considertion is ganging 2 narrow motorcycle hydraulic lifts

Electric linear actuators driven by AC motors and switched together should give you an even rise and lowering of the table. Jordan Controls and Beck Actuators come to mind as good quality stuff. I'll leave the googling to you.
