1).In case of straight roller conveyor. Roller length (W) ≥ conveying product width (W1) +50mm If conveying product’s bottom is flat and hard, it can be conveyed by overhanging, in this case, please select roller length (W)=conveying product width(W1)*70~80%. 2).In case of curve roller conveyor. In this case, roller length is decided […]

1).Conveying product checking. (1)Outer size checking: Width(W)*Length(L)*Height(H); (2)Conveying Direction; (3)Weight of each conveying product; (4)Shape and material: corrugated box, plastic box, wooden box; (5)Bottom shape: flat, uneven; (6)Conveying product quantity: how many conveying products will be placed on conveyor? (7)Placing way: how to place conveying product on conveyor?Hoist, crane, forklift and hand. 2).Application environment checking. […]
1. Calculation rule: Please calculate roller pitch based on that conveyed product can contact at lease 4 rollers. P<=conveyed product Length(L)/4 2. Sometimes, conveyed product can not directly contact roller because conveyed product’s bottom is not flat. So, we need to pay more attention to select roller pitch and roller load weight.
Gravity roller’s strength is different by conveyed product’s bottom side material and loading impact force. 1) Gravity roller loading weight calculation formula. (A)Conveyed product’s bottom is hard and not deformed(for example, steel,plastc） Gravity roller loading weight for 1 pc=conveyed product(1 pc)/2. (B)Conveyed product’s Bottom is flexible. Gravity roller loading weight […]
