Features
- Turning ability enables belt to avoid obstacles, operate in limited space, and eliminate troublesome transfers.
- Elongated slots allow pickets to nest, giving the belt the ability to turn and also providing for easy and
thorough cleaning.
- Stainless steel Key-Turn belts are USDA approved for use in federally inspected meat and poultry plants.
- H series sprockets for heavy duty belts are suitable for Key-Turn belts.
Turning Radius
- Minimum belt turning radius is equal to 2.2 times the belt width, measured on the inside radius of the belt.
- No maximum turning radius.
- For tighter turns, two or more narrow width belts divided by a rail may be used.
- Conveyor should be designed to include a straight run 3 times the belt's width before engaging sprockets
after a turn.
- Consult Keystone Manufacturing before using the belt in a non-powered turn situation, as this set-up
can cause excessive strain.
- Maximum allowable drive tension is 300 pounds.
- For belt speeds above 15 feet/minute, maximum drive tension is reduced to 200 pounds.
- Both load and return side belt supports should be either rollers or UHMW polyethylene to reduce friction
to a minimum.
