Here is a new topic- sure to have different approaches! As a parts and service sales rep years ago for a large Cat dealership I presented my "case" for using our Preventative Maintenance Services. Part of the service offered was adjusting the lift chains. As I think back to part of the checklist the mechanics I represented were going to take care of- I realize now how close to impossible this task really is. Figuring an hour or less for a 5000# capacity IC truck doesn't leave much time for this. AND, between tires worn beyond limits, operators "spiking" their forks beneath pallets and the condition of many floors- is there a reason to even try?? We all learned that on a vertical mast you want 1/4-1/2" of clearance between the heel of the fork and the concrete. Heck, you could eat up 15-20 minutes on a triple mast between the primary and secondary lift chains. And most older lifts are limited on internal hosing, so you are possibly creating slack. So.....
How do you guys handle it?
*What is your preferred lubricant. We use chain lube, but I prefer hydraulic oil in a squirt can.
*Do you adjust the secondary lift chains?
*Are you checking the fork wear with a go/ no go gauge? How about the chain pitch??
