Roach Screw Type Auxiliary Take-Up (for Live Rollers)

TYPE: Conveyor Accessories

MODEL: Take up

Most screw type take-ups ensure adequate tension on conveyor belts. They are the most common type of take-up. With screw take-up systems, the take-up pulley rotates in two bearing blocks which may slide on stationery guide ways with the help of two screws. The tension is created by the two screws which are tightened and periodically adjusted with a spanner.

It is preferable to use screws with trapezoidal thread to decrease the effort required to tighten the belt. 

Screw type auxiliary take-ups are the most common take-ups used on Roach Models 138VP, 196VP, 138LR, 196CALR196ZPA and 251CALR for additional belt take-up.


All belt conveyors require the use of some form of take up device to ensure:

  • Adequate tension on the belt leaving the drive pulley to avoid any slippage of the belt
  • Proper belt tension at the loading and other points along the conveyor
  • To compensate for changes in belt length due to elongation; and
  • To provide extra length of belt when necessary for splicing purposes.
