4.2.8.2 Free Flow Conveyor

Figure 4.20 Free Flow Conveyor

T_max = 2.1 × m × (L₁ + L₂) × f₁ × (g / 1,000) + M × L₁ × f₁

× (g / 1,000) + M₁ × L₂ × f₂ × (g / 1,000) (kN)

L₁: Length of conveying portion (m).
L₂: Length of accumulating portion (m).
M₁: Weight of conveyed objects in accumulating portion (kg/m).

Table 4.5 shows the allowable carrying load for each size of large pitch conveyor chain when it is used in horizontal conveyance.
