selection guidelines i confirm operating conditions for double plusŪ conveyor 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 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 tt wt xfxk tt total chains tension kgf or lbs wt total weight of conveyed object except chain kg or lbs f coefficient of friction f=f2+f3 see table 2 k chain speed coefficient see table 3 note if two strands of chain are used multiply tt by 0.6 to find tension per strand 12
