Calculation Formula for Horizontal, Vertical and Gradient Conveyance<br />

The maximum static tension acting on the <strong>chain</strong> can be calculated from the following formula.<br />

Specifications of conveyor<br />

Unit<br />

T : Max. tension applied to the <strong>chain</strong> kN<br />

Q : Max. conveyance capacity t/h<br />

S : Conveyance speed m/min<br />

V : Vertical center distance between sprocket shafts m<br />

H : Horizontal center distance between sprocket shafts m<br />

L : Center distance between sprocket shafts m<br />

M : Weight of traveling parts (weight of <strong>chain</strong>, slats, buckets, etc.) k/m<br />

f1 : Coefficient of friction between <strong>chain</strong> and guide rail<br />

f2 : Coefficient of friction between conveyed articles and bottom and/or side plates<br />

: Mechanical transmission efficiency of drive<br />

kW : Required power<br />

kW<br />

g : Gravitational acceleration 9.80665m/S 2<br />

W : Total weight of conveyed articles on the conveyor (maximum value)<br />

Note: If the results of H f1 - V and/or V -H f1 are less than zero,<br />

adopt zero for those values.<br />
