There’s a Maxi-DUB swivel leaving our Service Center this week, serial number 250-102. The first three digits are the tonnage – 250 tons. The second three digits are the production number – the second one made. (That pattern is standard for any of our big-rig swivels, btw.)
This swivel is something special: it was built in the fall of 1998, and delivered for service on the 12th of November that year. It’s probably the oldest Maxi-DUB swivel in service these days! *
 

We’ve seen it in for service three or four times over the 11 years since. When it came in this year for a routine service, I asked the mechanic to get a few photos, thinking I could write it up to show how regular maintenance will prolong the lifespan of the swivel.
I hadn’t expected it to be so banged up after a year in service! Still, the mechanic worked through it, cleaned it up, and replaced the necessary parts. It looked worse than it was.
Others have tried to duplicate the Maxi-DUB swivel but after years of service and hundreds of swivels, our patented design continues to prove itself. Other manufacturers can’t claim that.
* By the way, if you’ve got a record-breaker, let us know! Send us a photo and we’ll feature it here.
