Need some help to build a machine for lifting and pulling of weight 1000 kg approx.
Lifting and pulling what? It's hard to make suggestions with no info on job.
worm gear is one of the solutions.
Equivalent 2200 lbs. If movement of the load is involved, there are complications. Pure lifting is easy enough with a ratchet or chain lift hung from an A frame. Question remains what you mean by 'pulling'. Lowering mass onto a skid and pulling with an off-road winch is very commonplace. Main issues are anchor point, distance and whether an incline is involved.
Think like ancient Egyptian, Roman or Grecian. If I can get a 2500lb bandsaw on my tilt bed trailer, (two separate machines and occasions, I like bandsaws) by myself anybody can. Used two speed manual boat trailer winch loaded with tow strap, wooden peeler cores as rollers. Built a winch mount on receiver hitch for my little 4wd truck. Detach trailer, chock trailer wheels, move vehicle forward about 8 feet, park in neutral and chock it as well. This benefits catenary effect (lowers pull effort parallel to ground). Pay out winch strap and attach. Pry machine up for first roller, [nice with an assistant to keep the rollers fed from the front], start cranking and watch reaction of onlookers.
