Megaroller HDPE Rollers

Megaroller  HDPE  Rollers  are  an  innovaCon  in  reinforced  high-­‐density  polyethylene  (HDPE)  conveyor  rollers.  

Megaroller HDPE Rollers q  Megaroller  HDPE  Rollers  are  available  in  

Ø  Standard  •  high-­‐resistance  to  wear  by  abrasion  •  ultra-­‐violet  rays  •  used  in  the  harshest  weather  condiCons  and  in  moisture-­‐rich  environments.  

Ø  AnC-­‐Seize  •  UClizes  a  side  flinger  which  remains  staCc  while  the  roller  is  running  •  protects  the  sealing  arrangement  against  any  spillage  that  could  get  lodged  between  the  shaV  and  the  roller’s  side  face.  

Ø  AnC-­‐  Run-­‐Back  •  applied  to  incline  belts  to  prevent  the  belt  from  running  back  in  the  event  of  a  “belt-­‐snap”.  

•  fiDed  with  a  roller  brake  system  which  ensures  that  the  roller  can  only  run  in  one  direcCon.  

Megaroller HDPE Rollers q Main  Advantages  

Ø  Excellent  abrasion  resistance  Ø  Long  lifespan  Ø  Can  be  used  in  almost  any  applicaCon  where  steel  rollers  are  used  Ø  40%  Lighter  than  steel  roller  Ø  Lower  start-­‐up  costs  on  conveyer  drives  thanks  to  lighter  weight  Ø  Recyclable  Ø  Decreases  vibraCon  Ø  Lowers  maintenance  costs  Ø  Minimises  damage  to  conveyer  belts  Ø  Quieter  operaCon  than  convenConal  steel  rollers  Ø  Energy  efficient  Ø  Water  Cght  sealing  arrangement  Ø  Extends  the  lifespan  of  bearings  Ø  CompeCCve  pricing  Ø  Reduces  Total  Cost  of  Ownership  Ø   Performs  well  in  harsh  weather  and  extreme  applicaCons  

Megaroller Hybrid Steel Rollers The  Hybrid  steel  roller  is  a  new  development,  using  the  tested  and  proven  bearing  housing  and  sealing  arrangement  with  standard  conveyor  tubing.  

Megaroller Megahybrid Steel Roller q  Megaroller  Hybrid  Steel  Rollers  are  available  in    

Ø  Standard  •  Are  made  from  mild  steel  conveyor  tubing  for  maximum  strength  •  Patented  sealing  arrangements  allows  rollers  to  be  used  in  extreme  temperatures  and  harsh  weather  condiCons.  

Ø  AnC  -­‐  Run-­‐Back  •  applied  to  incline  belts  to  prevent  the  belt  from  running  back  in  the  event  of  a  “belt-­‐snap”.  

•  fiDed  with  a  roller  brake  system  which  ensures  that  the  roller  can  only  run  in  one  direcCon.  

Ø  AnC  -­‐  StaCc    •  StaCc  electricity  is  earthed  inside  the  roller  to  miCgate  the  risk  of  an  open  spark  in  methane-­‐rich  underground  mines,  which  presents  a  major  fire  hazard  in  cole  and  gold  mines.
