Undercarriage /Pin-on Guide Rail/
First crawler frame set was installed on a 495HR shovel August 2013
–1st set has run 25,000+ hours
–Last structural inspection revealed no cracking
–The previous cracking on the truck frame has ceased to progress
–4 converted, one additional set in fabrication

P&H patent pending, low friction, pin-on guide rails increase the life of new crawler shoes and side frame by reducing drag forces exerted by the crawler shoes, resulting in lower stress levels
Field validation proved plastic remained intact for 153 propel hours which is equivalent to almost 2500 SMU hours (Above engineering’s expectation of 1000 SMU hours)
