We set the standard for crawler shoe and drive system quality and durability.

P&H Delta Series Crawler Shoes

  • Designed to reduce maintenance and eliminate unscheduled downtime
  • Longer maintenance intervals reduces employee exposure to safety risks from maintenance activities
  • Longer crawler system life increases change-out intervals reducing employee exposure to safety risks from system change-outs and component replacement

P&H Delta Drive System

  • Self-seeking pitch design smooths engagement between shoes and tumbler, even when worn
  • Reduces drive lug wear on both shoes and tumblers
  • Longer crawler system life increases change-out intervals reducing employee exposure to safety risks

P&H Front Idler

  • Splined connection between idler and shaft provides more bearing area and better torque transfer, increasing reliability and matching idler life with that of other lower works components
  • Rotating shaft within stationary bushings produces less contact stress and wear
  • Longer crawler system life increases change-out intervals reducing employee exposure to safety risks

P&H Guide Rail Assembly

  • Extends life of the guide rail to minimize change-outs and maintenance activities
  • Wider profiled guide rail matches the profile of the crawler shoe path to minimize the wear between the shoes and guide rails
  • Longer crawler system life increases change-out intervals reducing employee exposure to safety risks

P&H Lower Roller Assembly

  • Helps to maintain system clearances and extend overall life of the crawler system
  • Larger and thicker thrust washer provides longer roller life and prevents damage to side frames
  • Longer crawler system life increases change-out intervals reducing employee exposure to safety risks
