Conveyor Terminology

  • Bed (slider): The formed steel sheet the belt runs on.
  • Bed length: The lengths of fabricated steel profiles, which are joined together to make up the conveyor length.
  • Bed width: Refers to the overall width of the bed section
  • Belt: Manufactured from PVC / PU / rubber / PTFE or cotton, dependent on application, is continuous and flexible as it fits around the end pulleys for the product sit on
  • Belt scraper: Normally a rigid plastic or a brush, this is used to clean the belt
  • Belt speed: The required speed of the conveyor, across the length of the conveyor. Normally metres per second.
  • Belt width: The width of the conveyor belt (not the overall width)
  • Braked motor: The motor is fitted with a safety brake inside to prevent product roll back. Normally recommended on incline conveyors
  • Casters: These are fitted to the underside of legs to allow the conveyor to be mobile
  • Ceiling Hangers: as support stands but ceiling mounted
  • Centre Drive: When the conveyor drive is fitted underneath the conveyor in the middle. Normally used in reversing, long or incline conveyors.
  • Chain Guard: A fabricated cover to enclose exposed chains.
  • Chute: A fabricated trough through which objects ejected from the conveyor.
  • Cleat: An attachment fitted to the conveyor belt to aid positive drive to the product.
  • Converging conveyor: A section of conveyor where two conveyors meet and merge into one conveyor.
  • Cross Bracing: Steel fixed in a diagonal form, to provide additional stability to the stand.
  • Crowned Pulley: The end roller has a taper section machined into it which is even from each side.
  • Decline Conveyor: A downhill conveyor.
  • Degree of Incline: Angle the conveyor is going uphill.
  • Discharge end: the outfeed end of the conveyor.
  • Drive: A electro/mechanical part which provides the means of belt movement
  • Drive Pulley: A end roller which has the drive attached
  • Emergency Pull Cord: a length of plastic covered steel wire which runs the length of the conveyor, that works with the emergency stop circuits.
  • Emergency Stop button: Electrical button used to stop the conveyor in an emergency.
  • Feeder Hopper: A fabricated item on the infeed of the conveyor to guide items onto the belt.
  • Floor Supports: Support structure for the conveyors which is floor mounted.
  • Flow: The direction of travel of the conveyor.
  • FPM: Feet per minute.
  • Horizontal Floor Space: Floor space required by the conveyor.
  • Horsepower: (HP) Motor power
  • HZ: HERTZ – Electrical term for sine wave frequency. Varied using an inverter to change the conveyor speed
  • Incline Conveyor: A Conveyor transporting up a slope.
  • Infeed End: The end of a conveyor be parts are fed on
  • Lacing: Means of joing the conveyor belt.
  • Lagged Pulley: A coating applied to the drive drum to prevent the belt the belt from slipping
  • Manual Start Switch: A simple switch used to start or stop the conveyor.
  • Motors: Same as drive.
  • Nip Guard: A plate placed to eliminate danger points on the conveyor.
  • Noseover: The section of conveyor going from incline to horizontal.
  • Overall Length: The total length over the.
  • Overall Width: The total dimension outside the conveyors frame.
  • Photo Electric Cell: Electrical devices used to detect the product.
  • Pop-Out Roller: A safety device often fitted to the end of the conveyor on a fixed point transfer, which pops out to create a gap to release fingers etc.
  • Portable Conveyor: A conveyor with wheels
  • Powered Feeder: The low end of a inclined conveyor
  • Pulley: The end roller of the conveyor
  • Push Button Station: An electrical device to start and stop the conveyor.
  • Return Idler: A roller which supports the return underside of the belt.
  • Reversible: A conveyor which is designed to run in either direction.
  • Roller Bed: used to reduce friction under belt – enabling smaller motors.
  • Shaft Mounted: when the motor is mounted on the end of the drive roller
  • Slider Bed: The fabricated part of the conveyor the belt sits on.
  • Snub Roller: Used to increase the contact between a belt and drive pulley.
  • Support: The structure used to carry the conveyor beds to the correct height
  • Tail Pulley: A pulley mounted at the infeed of the conveyor.
  • Take-Up: The means to take slack out of the belt
  • Terminal Roller: As tail pulley.
  • Throughput: The amount of product moved with a time.
  • Total Load: Maximum amount of weight on the conveyor.
  • Tracking: Used to direct the belt.
  • Tread Plates: Diamond top steel filler plates used to fill the gap between rollers on roller conveyor.
  • Through bed: a conveyor designed with a U shaped profile used for carrying powers, rubble etc
  • Under guard: Sheet metal used to protect the underneath side of a conveyor.
