Both tracks can go up or down, and can optionally be reversible. Only
one drive motor is required for each track. Models with dual 12-in. or
16-in. wide slats are available. Spirals are chain slat type and
incorporate a proprietary low friction design which facilitates high
speed, low noise, smooth operation and long life. All bearings are
sealed for life and do not need further lubrication. Spirals do not require water lubricants for proper flow. Modular design allows Ryson
to customize with ease and modify in the field to accommodate emerging
needs. Conveyors need less floor space than conventional conveyors, and most models ship in one piece.
