Large Oval Washer

Use with Ref 70 bolts in heavy duty applications.

  • Available in Zinc-Plated Steel / Stainless Steel 304
  • Locates over 4 lugs on bolt head, increasing effective bolt head size and bolt holding
  • Belt must be thick enough to absorb the washer and / or the bucket belt holes should be recessed
  • Not recommended on pulley diameters of less than 20” (500mm)
  • Fit the longest part of the oval across the belt width

 

Is the installation of Ref70 bolts any different to other elevator bolts?

When using the large Reference 70™ (REF 70™) oval washer with the REF 70™ bolt, the washer should be placed with the widest part across the belt in order to minimize stress on the system as it passes around the curved pulley. 

Note:  the bolt head and oval washer are installed on the back of the belt.
