Carryway wearstrips or rollers that engage the tabs are only required at the transition between the horizontal sections and angled sections. This approach reduces initial system cost, as well as ongoing maintenance cost and effort.
Ensure that adequate lead-in radii and/or angles are used to prevent the possibility of snagging the tab on the frame.
Place tabs in every other row (2.9 in [73.2 mm]) along the length of the belt. Tabs can be placed every fourth row (5.8 in [146.3 mm]) for lightly loaded applications.
Each line of tabs along the length of the belt reduces the available number of sprockets by two. Belt rating is reduced by 1,300 lbf (5,780 N) for each line of tabs.
When designing conveyors, include a carryway radius at the transition between horizontal sections and angled sections. This radius must be at least 48 in (1.22 m) for belts that are loaded near the belt strength rating. This radius is one of the most important factors to consider when designing highly loaded conveyors that utilize hold down tabs.
Strength rating for each hold down tab: 100 lbf (445 N) of force perpendicular to the hold down surface.
