John Crichton: "Pilot, get a tractor beam on that shuttle."
Pilot: "Tractor beam? What's that?"
Crichton: "Graviton field, attracto ray, superglue. Whatever it is you yanked me aboard with."
Pilot: "You mean the docking web."
— FarscapeClassic Applied Phlebotinum found on many, many space ships in fiction. At the press of a button, a beam of light comes out of the ship and sucks in anything in its reach. Occasionally used to move things already on the ship, too. The Tractor Beam thus allows space travellers to capture enemy ships, travel to the surface of planets, and steal the farmer's cows. Many stories with Alien Abductions use this as the means of abduction—a small tractor beam just big enough to pull one human. Of course, that kind tends to run in reverse as well. Not to be confused with Weapons That Suck.

Anime and Manga
- Called "Gravity Cranes" in Cannon God Exaxxion. Explained as an application of Artificial Gravity technology, the series gets a lot of mileage out of the different uses they have. For instance, using them in reverse to crush things or shoot holes in buildings with blasts of pure, concentrated gravity.
- Examples from the Calvinverse:
"THAT DUMB HAMSTER BUILT IN A SHIELD, LASERS, AND HIGH TECH LAVA PROOF METAL, BUT HE CAN'T PUT IN A STUPID BEAMER!"
- Dr. Brainstorm uses one to capture Calvin and Hobbes in one episode of Calvin and Hobbes: The Series.
- Star Wars universe:
- A New Hope Vader's Star Destroyer pulls Princess Leia's consular ship into the Star Destroyer at the beginning and the Millennium Falcon is pulled into the Death Star with one after it reaches the Alderaan system.
- The Empire Strikes Back. At the end of the movie, Vader's Super Star Destroyer is about to grab the Millennium Falcon with one when the Falcon's hyperdrive finally starts working.
- Spaceballs has one of these, too (called a "magnetic beam" in the film).
- In Austin Powers in Goldmember, both Goldmember and Dr. Evil came up with designs for a tractor beam to allow them to pull in an asteroid down to Earth. Dr. Evil calls his "Preparation H", as Preparations A-G were unsuccessful.
- The project itself is called the Alan Parsons Project after the head researcher. Scott mentions that it's the name of a band, but Dr. Evil doesn't get the reference.
- The ZARYa in the Soviet film Moscow — Cassiopeia has a "force field" that appears to act this way. It's only mentioned, though, as the target is beyond its range at that point.
- Shows up in at least three occasions in Guardians of the Galaxy:
- Used early on by Yondu to abduct little Peter and again later when saving him and Gamora from freezing to death in space.
- Nebula's Necrocraft has one which she uses to collect the orb with after blowing Gamora's ship apart.
- Tractor beams and ways to get out of them appear regularly in the Star Wars Expanded Universe.
- In The Thrawn Trilogy, Luke got out of one by dropping a hastily reprogrammed proton torpedo, letting it get drawn up by the tractor beam to destroy its projector, and doing something unorthodox with his engines at the same time. Later in the trilogy he's caught again and escapes by making an empty freighter explode into a cloud of highly reflective particles, breaking the lock despite the operator's best efforts. Thrawn did not kill that operator, instead recognizing that he made a novel effort and tasking him with figuring out an effective counter. And evidently he did; the trick doesn't work in the Hand of Thrawn duology.
- The X-Wing Series makes it clear that if a ship tractors something with a larger mass, the ship is pulled towards that mass instead of the other way around. In Wraith Squadron, Wedge uses this to move a ship without giving off drive emissions. In a simulation in Isard's Revenge, Corran tractors a space station, using it to make an even tighter turn than the TIE Defender he's flying is normally capable of.
- In Galaxy of Fear there's a book with scenes on an asteroid too small to have much gravity. There's Artificial Gravity on a base, but otherwise characters use special boots with tractor beams in them to move about. They can also be used to climb vertical surfaces in gravity, but with difficulty - they're very heavy.
- A possible Ur-Example is Jusel Verne's The Meteor Hunt, written in 1901 and published in 1908, where such a beam is used to bring the titular meteor down to Earth.
- One of the functions of effectors in Iain M. Banks's Culture novels.
- Rudyard Kipling, in the 1912 short story "As Easy as ABC", featured an effect referred to as a "flying loop," which John Brunner called the first-ever use of the tractor-beam concept. When a woman tried to commit suicide to make a political point, the "loop" yanked the knife out of her hand:
She threw out her right arm with a knife in it. Before the blade could be returned to her throat or her bosom it was twitched from her grip, sparked as it flew out of the shadow of the ship above, and fell flashing in the sunshine at the foot of the Statue fifty yards away. The outflung arm was arrested, rigid as a bar for an instant, till the releasing circuit permitted her to bring it slowly to her side.
- Mentioned and used several times in Alan Dean Foster's Humanx Commonwealth Space Opera series.
- Used as a weapon in the Mc Cade series by William C Deitz, where the main character is struck by one while in space. Then some sneaky git kicks it into reverse and turns him into 'one big bruise'.
- Featured regularly, along with their opposite, Pressor Beams, in E. E. “Doc” Smith's Skylark and Lensman novel series, which may well have originated the term. Also "tractor shears", which are planes of force capable of breaking a tractor beam.
- Lois McMaster Bujold's Vorkosigan Saga features tractor beams at military scale, including on starships, but also in civilian use at smaller scale - 'hand tractors' are used for cargo manipulation, and 'medical hand tractors' are used for delicate surgical work - ideal for battlefield medicine as they're fundamentally sterile, never physically touching the patient.
- David Weber's Honor Harrington series uses gravity-based tractor beams for tugboats, search and rescue operations, and towing missile pods. Apparently, with the limiters turned off, they can shred a ship at short range. Powered up even further, they form the basis for a stealth drive that pulls itself by poking hole into hyperspace and grabbing it.
- Vital in cargo handling and rescue operations in James White's Sector General series. One weapon system consists of using a tractor beam and a pressor beam on the same target.
- In an early Star Trek novel, Spock Must Die!, it's stated that tractor beams can only be used to pull, not push. To achieve a "push" effect, Scotty has to use a tuned beam from the main deflector.
- Used in the first Arrivals from the Dark novel called Invasion, where an alien starship pulls an Earth cruiser in for a closer look. Since the starship's Deflector Shield is masking it from human radar systems, the cruise's captain has no idea why the ship is suddenly moving forward despite the retro-rockets firing.
Live Action TV
- Doctor Who: the TARDIS has one, first (certainly in the new series, anyway) used in "The Satan Pit", probably because a phone box pulling a massive spaceship looks very weird. Later used on a planet, which was weirder. In the original series it had one in The Creature from the Pit, but that story was the only time it was ever mentioned.
- The example in The Satan Pit was indeed a tractor beam. However, moving Earth in Journey's End was not. They actually looped the Cardiff spacetime rift (mentioned in Torchwood) around the TARDIS, and that was used to pull the planet (not the TARDIS's tractor beam).
- Farscape: The Flax, a tractor net designed to capture ships for destruction and salvage by pirates.
- Also, Moya has a "docking web," which is usually used to help damaged ships aboard. Much to Pilot's confusion, Crichton ends up calling it a tractor beam in an early episode.
- Used as a large scale, multipurpose tool in the Star Trek series. Except on Enterprise, where grappling-cables are used instead. Tractor beams have been invented, but the Vulcans didn't feel like sharing.
- The Searcher has one on Buck Rogers in the 25th Century.
- They Might Be Giants: "The Bee of the Bird of the Moth":
All are irresistibly directed by the suctionOf the hypnotizing tractor beam presenting a production...
- Attractor and pressor beams exist as superscience devices in GURPS: Ultra-Tech and Spaceships. They're mainly construction tools but powerful ones can be used in combat.
- Task Force Games
- Starfire likewise has tractor and presser beams. These not only pull (or push) enemy starships around, they also make it easier for your weapons to lock on to a tractored target, and can tear small fighters to pieces. They can be countered by installing a Shearing Plane on a starship, which negates all tractor and presser beams attempting to lock on to it.
- Star Fleet Battles is based on the Star Trek universe and most starships have tractor beams as standard equipment. In addition to grabbing enemy ships for the usual purposes (e.g. towing), they can be used in combat as well. Above the simulator room doors at Star Fleet Academy is written "Use your tractors, Dammit!"
- They can be used to grab an enemy ship and prevent it from launching a "wild weasel" shuttle. This allows the tractoring ship to fire seeking weapons such as plasma torpedoes and drones (missiles) into the tractored ship with no chance of missing. This tactic is known as the "Gorn Anchor" in honor of the race that uses it most often.
- They can grab enemy drones and hold them for later disposal.
- They can grab enemy shuttles and be used to "death drag" the shuttle to destruction by traveling at high speed.
- Monsterpocalypse features a Martian faction, who use some relatively small flying saucers equipped with these, as well as one Kaiju-size one.
- Robo Rally has both tractor beams and pressor beams as enhancements that may be used in lieu of the default laser weapon.
- Warhammer 40K: Ork weapons mount giant nuclear-powered tractor beams on their Humongous Mecha, mostly for anti-tank duty (and anti-infantry, by dropping the tank onto the infantry). In the tradition of keeping their weapons as straightforward as their tactics, it's called the Lifta-Droppa.
- The Excursion Funnels from Portal 2.
- The Jetman games (Lunar for the ZX Spectrum, and Solar on the NES) made heavy use of a tractor beam for carrying ship parts and fuel.
- Gravity guns:
- Thrust, the truly ancient computer game where you piloted a spacecraft through tunnels to pick up an object with your tractor beam and pulled it out again.
- Crops up in The Legend of Zelda: Majora's Mask, of all places - a golden tractor beam is used by the 'ghosts' to abduct cows (and the unfortunate Romani).
- Crypto's flying saucer in Destroy All Humans! has the Abducto Beam, which you can use to pick up tanks, smash them against buildings, drain them of their energy, and fling them out to sea; or you can use it to, you know, abduct people.
- Freelancer has a "tractor beam" that pulls in any nearby items. It actually teleports them into your cargo hold. No explanation is offered why its still called a tractor beam.
- In Starscape your fighter ships have a tractor beam used to suck in minerals from recently exploded asteroids.
- The main charater of Rocket: Robot on Wheels has a small, personalized tractor beam he uses to pick things up and throw them.
- Tractor Beams in Sword of the Stars can be mounted in nearly any large turret socket in the game. They're especially effective when mounted on rotating defense satellites orbiting planets, where they can grab attacking ships and smash them into the planet's surface. The game's AI for some species actually takes advantage of this.
- It would make more sense to do that with ships, at planets that aren't yours. Unfortunately the ships' Artificial Stupidity is not capable of this maneuver and the player's user interface is too clumsy to manually swing the target into the planet before the beam times out.
- Also a key part of the random encounter and Morrigi special unit "Colony Trap", first time someone attempts to colonize a trapped planet several drones launch and drag the fleet into the planet's gravity well with tractor beams.
- Frigates and Cruisers in Gratuitous Space Battles can be mounted with (blue) Tractor Beams, slowing the pesky-deadly fighters down to the point where slow tracking beams and missiles can kill them.
- They appear in the Space Empires series, along with their opposites, Repulsor Beams.
- One of the gadgets in Ratchet & Clank: Going Commando. It only works on objects with a special marking.
- The final Bowser level of Super Mario Galaxy has tractor beams that pull you from one planet to the next, but a Launch Star is actually used to get from the second-to-last planet to the one you fight Bowser himself on.
- In Super Mario Galaxy 2 however, tractor beams are now produced by large doors (which can only be opened by smashing meteorites into it) leading to the planet you fight Bowser on at the end of all three Bowser levels.
- The War Blimp boss in Heavy Weapon has a "Meteor Tractor Beam", it makes meteors rain on you shortly after it is fired.
- The Fallout 3 add on Mothership Zeta has the player abducted using a energy beam.
- Beyond Good & Evil's gravity lift's function as a voluntary tractor beam, allowing you to move up or down.
- In X3: Reunion and X3: Terran Conflict, tractor beams are a player-usable weapon, used mainly for towing ships and moving stations around. In a symptom of those games' broken economy, the factories that create them sometimes disappear before the player can buy one, forcing one to build a factory for an item the player only ever needs one of.
- Interestingly, tractor beams are programmed to be incapable of locking onto non-player-owned objects. This is mainly to prevent the obvious exploit where the player drags enemy vessels into stationary objects like asteroids. The "Super Tractorbeam" mod disables the restriction and allows tractor beams to pick up anything. Your pitiful freighter can become a weapon of mass destruction when you tether an asteroid behind it and start mashing ships and stations with it.
- The player's ship in Spore has one for grabbing items, and plants, and animals.
- There is a tractor spell in Final Fantasy XI. It's used to pull dead players' corpses only, thought (still usefull to pull them out of monster reach before resurecting them).
- The Dead Space series has gravity tethers, which can move massive amounts of rock into orbit. The player also has a smaller version in the form of the Kinesis module
- Tachyon: The Fringe has a Tractor Wave item that you can add to your fighter provided it has a slot for it. Unfortunately its short range and forward-facing targeting makes it something of a Useless Useful Spell.
- Present in the first two games in the Escape Velocity series, and possible but unused in the third. If one ship tractors another, the least massive ship is the one that gets pulled along. A larger ship can even use the tractor beam to prevent a smaller one from entering hyperspace. Mechanically, they're created by putting a negative number into the "impact" fieldnote of a Frickin' Laser Beam. There are also (equally unused but possible in the third) repulsion beams, who mechanically are simply beams with a positive number in the impact field but (like tractor beams) doing zero damage.
- Appears as a recurring non-elemental spell in the Tales Series, which lifts enemies and then drops them for damage.
- Muppy has a skill in Mana Khemia which summons a flying saucer to attack with this.
- Wing Commander II has one ship that has turrets equipped with a tractor beam along normal guns). It is used in one mission to retrieve a data recorder jettisoned when a ship blew up.
- Star Ruler features two versions of the tractor beam; one which will pull objects towards the ship (or station), and another which will push objects away from the ship. The devices are largely pointless, though it's always entertaining to use them to catapult an enemy's defense station out of orbit. Micromanaging a station with a repulsion tractor beam allows players to assist their ships when leaving the system, effectively giving them a big push; very useful with very large ships that are very heavy or have weak engines.
- The player's ship in Zigfrak has an electromagnetic tractor beam for the purpose of collecting loot and materials in space.
- Star Trek Online, given its source material, allows science bridge officers to learn a skill to use the ship's tractor beam in combat. It's a heavy speed debuff, though unless the target ship is already very slow it doesn't stop the target entirely. The Borg and the Tholians use this to deadly effect. There are also two other player-based Tractor Beams - Tractor Beam Repulsors, which push away enemies, and a DOFF skill that inverts the Repulsors, pulling them toward you.
- The first two Star Trek: Starfleet Command games use tractor beams as a passive defense against incoming missiles. If a tractor beam is set to missile intercept mode, it captures the nearest enemy missile and holds it in place relative to the ship until one of three things happen: the beam's power runs out and the missile continues on its course, the missile's fuel runs out and it disappears, the missile is destroyed by one of your point-defense phasers. They can also be used to keep enemy or friendly ships in place for a time. However, in the first game, a tractor beam cannot be rotated, which means the positioning can be a bit of a crapshoot. To counter a tractor beam, the enemy can change their tractor beams to "push".
- The Big Bad Wolf's breath in Activision's Oink! works like this when it touches one of your three little pigs.
- The Galaga flagship (a.k.a. Boss Galaga) from Galaga occasionally stops in mid-flight to emit a tractor beam in order to capture your ship.
- In the game sequel Gaplus, your ship can also emit a tractor beam that can capture aliens and use them to increase your firepower.
- The ZIG shuttle in Zero Wing has this to capture enemies, then toss them forward, Kirby-style.
- Time Crisis 4: Wild Dog, in previous games, has outfitted his gun-arm with flamethrower and rocket launcher attachments, but in 4 he employs a tractor beam for the final phase of his fight, throwing all manners of cargo containers at you. Elizabeth is surprised that an actual tractor beam exists. When defeated, the tractor beam malfunctions and pulls in the cargo towards him, crushing him under it...although he survives.
- X-COM: Interceptor has a ship mountable tractor beam. Using it disables the energy weapons, but not the missiles. Of course the effort of the ship trying to fight loose would damage both ships. They could also be mounted to stations, which would slow attacking alien ships for weapon turrets and defending fighters.
- One of the functions of gravitic technology in Schlock Mercenary is to act like this, usually referred to putting a ship in a "tractor-bubble" or "tractor-lock".
- Robot #1 in The Easy Breather uses a tractor beam to pull Ant Woman into its cargo hold.
- Wikipedian Greg Williams created an illustration◊ discussing tractor beams (with a side helping of Aliens Steal Cattle) in December 2007 as part of a series.
- The animated show Galaxy High once showed this with a Visual Pun: a beam with a farm tractor at the end.
- Tractor Beam abduction is spoofed to heck and back in the Pixar short film Lifted.
- Spoofed in just about every alien abduction episode of The Simpsons. In one, the tractor beam isn't strong enough to lift Homer and they end up having to use two. In another, Marge is hit with what looks like a tractor beam... and then a lasso drops down instead and yanks her into the flying saucer.
- In Recess: School's Out, the villain's plan is to aim the tractor beam at the moon to redirect its orbit causing a global ice age, eliminating summer vacations and forcing kids to study indoors making test scores go up.
- Scientists at the University of St. Andrews in the United Kingdom were able to create a tractor beam, although at a microscopic level. This can have many applications, like for medical usage.
