Selection Guidelines
I. Confirm operating conditions for DOUBLE PLUS ® conveyor.
II. Select initial chain size. The proper selection of DOUBLE PLUS Chain considers the vertical force exerted on the rollers, as well as the tension on the chain due to friction that results. Make initial chain selection based on maximum allowable chain tension. (See Table 1a or 1b.) T T = W T x f x K T T : Total chain(s) tension (kgf or lbs.) W T : Total weight of conveyed object except chain (kg or lbs.) f: Coefficient of friction f=f 2 +f 3 (See Table 2.) K: Chain speed coefficient (See Table 3.)
The following information is needed to select the appropriate chain: a. Material, weight, dimension, and quantity of the conveyed object (including pallet)
b. Conveyor speed
c. Conveyor length (the length for accumulating and transferring section respectively)
d. Lubrication requirements and environment
Note: If two strands of chain are used, multiply T T by 0.6 to find tension per strand.
