4B Polysur Ferro® Steel Web Cord Elevator Belting
         
 

The 4B Polysur Ferro® steel web cord belt is a rubber elevator belt with a special steel cord core. The cords provide low elongation with high elasticity in the length, and cross rigidity in the width. The built-in elasticity allows running over slightly crowned pulleys which greatly improves belt tracking, and helps to avoid belt wandering which is often the reason for elevators shutting down. The rigid weft cords act as a barrier to ripping and tearing which increases the holding ability for the bucket bolts. This produces a good cross rigid belt resulting in excellent straight tracking characteristics.

In contrast, most conventional steel cable belts lack elasticity and consequently have to run over truly flat, cylindrical pulleys which increases the risk of belts off-tracking.

The 4B Polysur® steel web core belt is designed for heavy duty/industrial bucket elevator applications with long centre distances that require stable running and reliable belts with high safety factors. All

4B Polysur® steel web cord belts are manufactured in accordance with DIN 22102 and ISO norms.

Euro DIN 15237 Elevator Bolts

Euro DIN 15237 elevator bolts have a concave head and two lugs on the underside to help prevent rotation when tightening.  Euro DIN 15237 bolts are available with POSIDRIV® ends, which are recommended for use with 4B Polysur® steel web core belts.

Braime Clamp Belt Splice
  

Braime Clamp Belt Splices

The Braime Clamp (BC) series of heavy-duty belt splices securely fastens belting on larger bucket elevators.  The BC2, BC3 and BC4 versions incorporate an additional three piece machined steel vise grip section designed to ride above the aluminum base clamp and secure the steel cords within a steel web core belt.

  Do I have to use the Braime Clamp (BC) splice with Polysur® steel web core belting?  
  Yes, the Braime Clamp (BC2, BC3 and BC4) was specifically designed for steel web core belting.  
     
  Can the BC1 version of the Braime Clamp be used with Polysur® steel web core belting?  
  No, the BC1 is for textile belts only.  The BC2, BC3 and BC4 versions incorporate an additional three piece vise grip  
  section designed to secure the steel cords.  
     
  Is there a specific type of elevator bolt to use with Polysur® steel web core belting?  
  4B recommends Euro DIN 15237 elevator bolts with hex keyed ends.   The hex keyed ends make installation much  
  easier when trying to get the bolt through the steel web core.  Using a hex or allen wrench allows you to "screw" the  
  bolt through the steel webbing.
