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

P&H Final Drive Upgrade

  • Increased spline length between tumbler and shaft interface reduces stresses on the spline
  • Sealing arrangement engineered to keep dirt out and grease in place to keep bearing running clean

P&H Crawler Frame Upgrade

  • Ideal for models 301M, 495HR, 495HF, and 7495
  • Interchangeable with OEM side frames
  • Designed to accept different mounting and transmission configurations

P&H 10-inch Delta Conversion

  • Improves lower works life up to 26,500 hours
  • Features 66- or 76-inch heavy-duty manganese crawler shoes

P&H 11-inch Delta Conversion

  • Improves lower works life up to 30,000 hours
  • Features 130-inch heavy-duty solid-core manganese crawler shoes
  • Features 76- or 87-inch standard or heavy-duty manganese crawler shoes

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

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 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 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 Delta Drive System

  • Self-seeking pitch design smoothes 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
