How to Make a Massive Electrical Vise - 4 Tons!!!
Construction of homemade electric clamps, with electric piston reaching 4 tons closing power !! You also had to build a very strong base to carry the pressure intensity the plunger runs at closing. This is the most expensive project I've ever done! The cost of electric plunger about $ 1000!

Looks a lot like an electric log splitter.

I'm not sure where electric actuators are used, and can only guess at the internals; a pressure cylinder or a screw.
My inclination would lean towards a far shorter stroke and multiple attachment points along the bed, like a quick setting grinder vise.
One viable concern is rigidity of an extended ram against side-forces typical in milling. Such use is commonly addressed by dovetails, gibbed slide ways, or guide bars.
An ideal application would emulate 2 piece milling bed vises. Common vises are tedious operating their screw with that axis over the table.
