Take-up Options for Belt Conveyors - FEECO International …

· Belt Conveyors for bulk materials: Take up Arrangement: All belt conveyors require the use of some form of take up device for the following reasons: 1. To ensure adequate tension of the belt leaving the drive pulley so us to avoid any slippage of the belt. 2. To ensure proper belt tension at the loading and other points along the conveyor. 3.

Conveyor Belt Tensioning Techniques

If excess belt length accumulates loosely on the return path the belt may slip or jump off the drive sprockets. Take-up of slack can be done in several ways: The simplest method is to allow the belt to sag on the return side of the belt circuit (called a catenary). The weight of the belt itself keeps the needed tension on the drive shaft.

Pros and cons of using double take up pulley arrangement?

· Recently in one of our projects, we used double take up pulley arrangement as a part of VGTU (vertical gravity take up unit) as shown in the attached sketch. Single counter weight frame was attached to two take up pulleys for tensioning. Even though for attaining the same slack side tension, we have to use more counter weights compared to single take up pulley arrangement, this arrangement ...
