JKR Series with M Style attachments

The preference in most North American Asphalt production equipment is for material to be premixed and then transported in its finished condition with inclined drag slats and delivered to heated storage bins for ongoing distribution. The Engineering Roller Drag chains (JKR) highlighted are the most commonly encountered types, with M attachments. In either single or double strand format, the flights are generally welded into position. As they are in direct contact with the material they are normally produced from a pre-hardened steel plate. In the case of twin strand operation it is recommended chains are requested in calibrated and matched strands to ensure the strands operate in unison.
