Expander Ripper Pins

Background:

This copper mine serviced by SMS in British Columbia Canada has been using the Expander system on their Cat D10T dozers for 10 years. When the mine purchases new dozers for their fleet the OEM pin is immediately replaced with Expander pins before going to work. In the case of the dozers there are unique pin clearance issues to deal with and Expander has the solution. In the lift frame to frame position the tracks must be removed to set up line boring equipment Expander is easily installed without the additional work. Expander also offers a bolt through design which can be installed from one side eliminating the problems faced when there is tight clearance or a blind hole on the opposite side. The savings and reduced repair time are clear to the customer as they also use the Expander system for standard maintenance on their surface drills and trucks.. The Expander D10T &R pins are utilized by many locations throughout North America.

Expander Stabilizer & Suspension Pins

Background:

As a result of an Expander presentation this mine customer in the Powder River Basin Wyoming decided to conduct a trial of the Expander System. They had a fleet of 50 Cat 793B trucks and were concerned about the cost and downtime during repair of the stabilizer and suspension positions. The conventional pins were making contact with the parent metal of the lug ears damaging the bores which required welding and line boring in each case. They ordered the Expander pins through the local KEC dealer and installed the first set. The test period for the Expander pins was short as they were easy to install with the sleeve taking up the wear in the bore eliminating welding and line boring altogether. The Expander system became the standard of repair for the entire fleet. This position application has been successfully utilized for Cat trucks by mines in the US, Canada, South America, Australia and Africa. There is also a large market for the Cat 789C truck which uses the same part numbers in these positions.
