# 4.2.8 Calculation of Tension

Here we have an example to determine the tension in a horizontal conveyor and free flow conveyor.

Terms

*T*: Maximum chain tension (kN)._{max}*T*: Static chain tension at each part of conveyor (kN).*Q*: Maximum weight of conveyed objects (t/h).*V*: Conveying speed (the chain speed). (m/min.).*H*: Vertical center distance between sprockets (m).*L*: Horizontal center distance between sprockets (m).*C*: Center distance between sprockets (m).*m*: Mass of the working portion of the chain (kg/m). The mass of the chain x number of the chain strands, bucket, apron, etc.*M*: Mass of the conveyed object in conveying section (kg/m).*f*: Coefficient of friction between the chain and the guide rail when conveying._{1}*f*: Coefficient of friction between the chain and the conveyed objects in the accumulating section._{2}
