• GUARDABELT™ Impact Cradles are installed so that bars in the center of the cradle are set slightly below - (3/4 in.) (19 mm) to 1/2 in. (13 mm) - the unloaded belt’s line of travel. This allows the belt to absorb impact while avoiding continuous friction and wear if the belt is running empty. The wing bars on the sides of the cradle are installed in line with the idlers to allow effective sealing of the transfer point.
• When installing one or more GUARDABELT™ Impact Cradles, it is necessary to verify there is adequate power in the conveyor drive to compensate for the additional frictional drag. Consult Martin Engineering for additional information.
• Standard base stringer width is the belt width plus 12 in. (305 mm). Mounting centers width is the belt width plus 9 in. (229 mm). Wide base stringer width is the belt width plus 18 in. (457 mm). Mounting centers width is belt width plus 15 in. (381 mm).
