Hi Wolfgang,
Welcome to the forum. My father pulled the motors and various parts off of hospital beds, lift chairs and other nursing home equipment. It is on the lightweight side but at least over here too much of that equipment gets thrown away with very few hours on it. I saw another bed going to the landfill the other day, 2 lift motors, controller and lots of steel, simply amazing.

lots of things you can use. The biggest question is do you want threaded rod, chain? use the existing setup and just add power?

I think on one of those the head moves pretty easy. I bet you could find a 12 volt wheelchair motor and connect right to the starter battery if you have one. Then just run roller chain to the original crank handle.

DC electric motors are fairly easy to use with speed control.  Torque at low speed depends on the how the motor is wound and on the speed controller.
Single phase AC motors generally run at full speed only although there are exceptions.
Three phase AC motors combined with a Variable Frequency Drive have good low speed torque and excellent speed control (cost more).  For small motors (3 hp or less) a Variable Frequency Drive can use single phase input to run a three phase motor.

Wolfgang,
Show us pictures of your present setup and we can be more specific in our suggestions.
