Automated Flexible Conveyor SPIRALFEEDER Push Unit flexible screw conveyor was developed to support worker safety. The AFC Push Unit sets the drive mechanism at floor level at the hopper rather than at the discharge to invite easy access to the electric motor and gearbox without requiring a ladder, mezzanine or other lifting device. Slips, falls and other safety issues involved with heights and climbing are eliminated along with concern for compliance with OSHA Standard 1910.23.
