Not to be confused with Inconveniently Placed Conveyor Belt, a common hazard in video games.
The main character(s) have become trapped on a conveyor belt (mining ore cart, log in a flume, or any other mechanized delivery system) responsible for shuttling them into a large blast furnace or incinerator, crusher or grinder, large rotary saw blade(s) or anything else that will give them a quick and painful end.
Sometimes this is done purposely by the villain (like tying the Damsel in Distress to railroad tracks) as part of (or in place of) a Death Trap, or as a method of interrogation (as an alternative to physical torture). Thus, often a part of Lumber Mill Mayhem. Or the heroes may wind up in such predicament by more or less coincidence, but still have to find a way to escape whatever machines whose job of processing and/or assembling raw materials is invariably lethal to their soft warm bodies.
Commonly seen in large mechanized factories, mills, mines, research labs — or any place with No OSHA Compliance. This may also provide the reason why the heroes always end up trying to run against the direction of the conveyor instead of, say, trying to leap off the side — it may be 1-Dimensional Thinking on the part of the writer, or perhaps the conveyor belt is situated high up where there really is nowhere else to jump to.
If the hero wasn't deliberately tied or trapped on this conveyor by a villain, expect them to trip over something, or get an arm or leg snagged underneath whatever debris or items normally travel the belt, just to up the tension. Likewise, if there are any Mooks trapped on the conveyor with the hero, expect them to be the first ones meeting whatever doom awaits at the downstream end. Depending on the length and path of the belt, sometimes the ultimate fate of the conveyor belt is unknown at first, giving everyone a moment to look up in shock once they realize exactly what they're being drawn towards.
Playing Raymond Scott's "Powerhouse" in the background during such a sequence is purely optional.
Originated as a standard Cliffhanger scenario in 19th-century melodramas and the silent matinee film serials that followed them, such as The Perils of Pauline (and echoed repeatedly on The Perils of Penelope Pitstop). Probably a Dead Horse Trope, at least in the dramatic sense. But then, it wasn't too bad in Enemy Mine.
- The theme of one commercial for Wilkins Coffee shows the spinning saw blade variety of this conveyor, on which Wilkins the frog, who loves Wilkins Coffee, puts Wontkins, who hates Wilkins, as punishment for not drinking the coffee.
Wilkins: He [Wontkins] always was a cutup!
- Kirby: Right Back at Ya! features this trope in a more classic fashion. In Episode 61 of the anime, there is a short scene in which Kirby is forced to run on a conveyor belt to avoid being speared by a plate of rotating spikes at the end of it in a part of a crazy exercise regime.
- Subverted in a Bronze Age Supergirl issue when the titular heroine tries to save a guy from a conveyor belt and finds the buzz saw is made from plastic. The conveyor belt wasn't supposed to cut the weak-hearted guy in half, it was meant to scare him to death.

Donald saves them in the nick of time by turning it off.
- A variation occurs in The Saga of Swamp Thing Vol. 1 #4 when a possessed man hangs Swamp Thing on a meat hook on a stationary conveyor belt leading to a freezer. Swamp Thing tricks the demon into possessing him instead and then starts the belt. While he can survive the cold for a short time, the demon can't.
- In "Capt. Sprocket Meets His Greatest Foe Dr. Neutron" in Mad House Comics Digest #5 Dr. Neutron freezes Captain Sprocket in a block of ice and puts it on a belt leading to an ice-cube-making machine.

- In Amy Potter Is Batgirl Amy and Hermione are tied to a conveyor belt in a bookbinding factory by The Joker. He actually returns them to the start of the belt several times when Batman and Robin take longer to arrive than he expected.
- Played straight in the New Zealand movie Footrot Flats: A Dog's Tale - the main canine character, Dog, ends up on a conveyor belt that is moving towards a swinging circular sawblade, three very vicious, very evil dogs surrounding the sides, ensuring he doesn't escape. He does, of course.
- Near the end of The Brave Little Toaster, the characters have become stuck in a junkyard filled primarily with (anthropomorphic) cars whose fate is to be placed on the conveyor by the resident electromagnetic crane and smashed to death in a teeth of a crusher at the end of the line.

- Toy Story:
- In Toy Story 2, while trying to rescue Woody from being shipped to Tokyo, the characters wind up in the airport's automated luggage processing center — a maze of conveyor belts and parcels, but (fortunately) none of it lethal.

- In Monsters, Inc., Sully thinks that Boo was trapped on one of these, when it was actually just a piece of her monster costume. In a way, this allows the scene to be much more gruesome than it otherwise would be, juding by Sully's reactions as he watches the costume-piece go through one crusher and thrasher after another, assuming Boo is in there.
- Chicken Run has the various machinery inside and leading into the Pie Machine, which is basically lots of conveyor belts all put together.
- Kung Fu Panda 2. Po gets caught on one made of bamboo in Lord Shen's cannon factory. Although he's not tied to it, Po can't run fast enough to avoid going over the edge into the smelter. Fortunately he's grabbed onto a fork that he can stick into the bamboo planks and get carried away underneath.
- Fender is placed on one and is able to escape before getting chopped to pieces and thrown into a furnace. However, it's a little embarrassing when he loses his original bottom half and has to do with one more suited for a female.
- Bigweld is also put on a conveyor, but is saved before getting dumped into the furnace as well.
- Farmhands somehow fail to notice that they're feeding Buster Keaton into a threshing machine in The Scarecrow.
- Roscoe "Fatty" Arbuckle (under a pseudonym) directed a short called "Curses", a parody of 1910s serials, in which the Damsel in Distress is strapped to the now iconic log headed for a sawblade. It's probably one of the first parodies of this type of scene.
- Subverted in the movie version of Dudley Do-Right, where the eponymous Mountie goes "bad" to fight against Snidely Whiplash, who has taken over the town. He ties one of Snidely's minions to a conveyor belt heading for a sawblade for interrogation. Once he has gleaned the information he needs, Dudley seems to have trouble stopping the conveyor belt — then he breaks apart the sawblade to reveal that the "saw" was just a harmless cardboard prop all along.
- James Bond:
Bond: Do you expect me to talk?
- In one of the film's most famous scenes, the eponymous villain of Goldfinger straps James Bond to a table and uses an industrial laser in place of the traditional sawblade; here, it is the peril that inexorably advances toward the hero, rather than the other way around (compare Chained to a Rock). Bonus points because of where on Bond the laser is headed.
Goldfinger: [laughing] No, Mr. Bond! I expect you to die!
- Parodied in Austin Powers in Goldmember, where Austin's father is strapped to a conveyor belt-esque contraption that would eventually pour liquid gold over his genitals.

- In the Jackie Chan Movie Mr Nice Guy, during the construction site fight, Jackie is knocked down on a piece of plywood sliding towards a circular saw, which he rolls out of the way of at the last second, then does a sideways roll over while it's still spinning. Remember, live stunts, no stuntman.
- There's another Jackie Chan movie with a conveyor belt o' doom. It's a sticky surface that gets chopped into lengths by blades at the end of the conveyor belt. Jackie and the girl get stuck on it while fighting mooks. In the end, Jackie gets himself and the girl off (with some Clothing Damage)... and then goes back and stops the belt just before the mooks get sliced into pieces.
- In Star Wars: Attack of the Clones, Anakin and Padme find themselves on a conveyor belt on Geonosis. Anakin battles Geonosians, and in the process has his lightsaber destroyed and his arm stamped on a metal plate. Padme falls in a giant crucible, and is only saved from being incinerated by molten metal by R2D2, who deactivates the machinery just in time.
- In Minority Report, the main character, John Anderton, finds himself on a conveyor belt on which machines are building cars, and fights his enemy on it. He manages to avoid the machines for a while, but in the end finds himself trapped in a car that's being built right around him. At a certain point we see a machine close in on him, then the camera cuts on the outside of the car, leaving the audience to think he has been squashed flat. Instead, as the car is completed we see he is right in it, and as it exits the factory he drives away from his pursuers.
- As an example where someone actually died in Child's Play 2, a factory worker is shoved in and has plastic eyes forced into his.

- The Ice Pirates has the castration factory.
- In Indiana Jones and the Temple of Doom, Indy fought a Thuggee guard on a conveyor belt that led to a rock crusher. Things were further complicated by the brainwashed prince stabbing a voodoo doll of Indy just as he gained the advantage in the fight. Indy of course escapes, the guard... doesn't.
- The same film features a cage that is used to lower human sacrifices into a large lava pit. Indy manages to save Willie from a fiery demise in this device, but an unnamed Sacrificial Lamb is not so lucky.
- In the film adaptation of Richie Rich, Professor Keenbean invents a sort of futuristic recycling machine that transforms trash into various objects. Later in the movie, the bad guys try to use the machine to dispose of Richie and his friends, who are forced into its cage-like intake hopper.

- Who Framed Roger Rabbit contains elements of this trope along with Chained to a Rock near the climax of the film, when Roger and Jessica Rabbit are suspended by chains while a nearby contraption spraying The Dip, Judge Dooms weapon of choice, inches ever closer. Notably comparable to Goldfinger, although this plays with the tension by having the stream swung back and forth haphazardly.
- The scene where Judge Doom gets his hand stuck to the steamroller and is slowly crushed contains the inescapability of the trope.
- In Showdown in Little Tokyo, Kenner and Murata are trapped in Kenner's car when the bad guys place it in a car crusher. Deciding that this isn't enough, they only crush it halfway and place them on a conveyor belt to be ground up into bits.
- E.B. from Hop gets immobilized and placed on a conveyor in the Easter Bunny's candy factory. The conveyor leads to robotic circular saws that cut large hunks of milk chocolate into manageable pieces. E.B. is able to wriggle and dodge around this mechanized Death Trap so well that his outfit remains intact while his bonds were eliminated.
- The Black Hole, though rather than a belt it's more a rotary device that carries the victims underneath some kind of lobotomizing laser. After discovering the crew of the USS Cygnus have been turned into robotic drones, The Chick is taken away to be turned into one also, with the requisite Just in Time rescue.
- The Anthony Horowitz book Skeleton Key has a scene like this too, where Alex Rider is drugged so he's unable to move except for his head, and put on a literal conveyor belt. The main purpose is to get information out of him, on threat of being ground to a pulp starting with his feet.
- Charles nearly gets his feet sliced into by the lumber mill's machinery in the fourth book of A Series of Unfortunate Events.

- The iconic laser scene in The Film of the Book Goldfinger, in Ian Fleming's original novel, used a circular saw - and Goldfinger did expect Bond to talk.
- Arguably the most horrific example occurs in the second book of Michael Vey; when Dr. Hatch shows off his giant rat-powered electricity generator to his electric children, he makes special note of the bowl's feeding conveyor belt. He puts Elgen guards who have failed him onto the conveyor belt to be fed to the rats. The process is horrific, as Taylor and the captured Electroclan can vouch for during Book 7; Hatch claims that the rats will jump like piranhas onto their next victim, so one doesn't even have to reach the end to die or see themselves disemboweled. And he keeps finding ways to make the process even more painful. Michael Vey is sent into the bowl during Book 2, but he survives because the electricity generated by it gives him a giant boost in power; he incinerates the rats and frees himself.

The tenants arrive in the entrance hall here, and are carried along the corridor on a conveyor belt in extreme comfort and past murals depicting Mediterranean scenes, towards the rotating knives. The last twenty feet of the corridor are heavily soundproofed. The blood pours down these chutes and the mangled flesh slurps into these...

Mr. Wiggin: Rotating knives.
Second City Gent: Are you proposing to slaughter our tenants?

- Wildly twisted in God of War 2: You can't get to the next area because there is a large crushing wheel blocking your way that is right in front of a Conveyor Belt-O-Doom that constantly tries to make you hit the damn thing. The solution? You find a half-dead member of Jason's Argonauts, bring him to the belt, lay him on it, and then watch as he screams in horror and is carried under the wheel where his crushed bones jam it, allowing you to break it and pass through.
- There are a couple of instances in the original game that are both straighter and infinitely more annoying.

Sure, his fellows are disturbed and distrustful of the Strogg on their side, but he never complains. And, in the end, it pays.
- In Portal, GLaDOS attempts to kill Chell by tricking her onto a conveyor belt that travels through a furnace. The trap would be extremely difficult to avoid had Chell not had a portal gun, which makes it very simple.
- Parodied in Portal 2, where one of last traps is a conveyor belt into a grinder which you escape by jumping off it onto a ledge on the thing's side—no portals necessary.

Naturally, the villain activates the conveyor again, and Jack survives only by jumping onto the catwalk over the grinder, which breaks and blocks the cogs. The whole episode is pretty nightmarish.

- In Mortal Kombat 9, Kung Lao's "Razor's Edge" Fatality creates a facsimile of the rotary blade version of this Trope even without an actual conveyor belt; After kicking his opponent to the ground, he throws his hat on the ground, turning it into a buzzsaw which he drags his opponent through, groin first, cutting them in half. (Ed Boon himself has admitted that this was brutal even for this game, saying that it was "probably the most painful-looking Fatality ever made." This sentiment is shared by many critics, including Cheat Code Central's Shelby Reiches, who included it among the four worst cinematic scenes in games, commenting: "Every time he does this to a male fighter, I can hardly watch. I try not to fight against Kung Lao anymore."

- In Scooby-Doo and Scrappy-Doo, the series premier had Shaggy, Scooby, and Scrappy, after splitting up from the rest of the group, get trapped on a conveyor belt that would have sliced them to pieces had it not been for a last minute burst of adrenaline on Scooby's part.
- One of these was set up by cliché devotee Señor Senior, Sr., on Kim Possible. At the end was a stolen cryogenic freezing device. As a keen observer of villain codes, he points out the power switch to them.
- But they can't reach it, and Rufus the naked mole rat doesn't weigh enough to push it.
- In Batman: The Animated Series, the deathtrap is neatly subverted, as Catwoman is carried to her doom while Batman has captured Harley Quinn, who tells him that he has to choose whether to keep her or save Catwoman.

- In Futurama, Fry has to choose between saving Bender, who is tied to the Conveyor Belt-O-Doom (which will turn him into Slurm cans), saving Leela, who is being dunked in a slurm-filled pit (which will turn her into a Slurm Queen), or drinking from a trough of delicious concentrated Slurm. He chooses the Slurm, of course. However, he saves Leela by dragging the trough with him, who then saves Bender. Hey, he was literally addicted to the stuff.
- Underdog has been in this situation three times, and Sweet Polly was in the same mess each time:
- In episode "Batty Man", Underdog and Polly are chained up and placed on a conveyor belt that goes to a machine that turns anything into bowling balls. Underdog is still able to access his Super Energy Pill, though.
- In "Pain Strikes Underdog", the conveyor belt is part of a candle-making machine that the villain Riff-Raff is using to disguise stolen swords as candles; in this case, both victims are bound with the wicks and hardened wax, the wick cutter intended to be used like a guillotine. (It even looks like one.) Unfortunately for Riff-Raff, wax and normal rope can't hold Underdog for long...
- In "The Silver Thieves", Underdog's ring has been stolen, he's already nearly powerless because of it, and he and Polly are thrown onto one that leads to a furnace designed to melt down silver. Fortunately, Polly is lucky enough to find the stolen ring there.
