Ski Lifts International (also known as SLI) was an Austrian chairlift manufacturer that was imported into the United States between 1965 and 1972.
Key Players
Sam Bonasso was a minor partner, but perhaps the term “North American sales engineer” is a better term.
Joe Sugarman was also a minor partner, but perhaps the term “marketing director” is a better term.
Some parts were made in Austria, some were outsourced from American manufacturers.
The Austrian firm entered the North American market in the mid 1960s at the height of ski lift building and ski area rebuilding.
Due to large sales in the Lake Tahoe area – Homewood, Incline Village, Heavenly Valley, Squaw Valley…and Heavenly Valley’s Maintenance Supervisor/Chairlift builder who happened to live in Incline Village NV (and who spoke the language) … a small space dedicated to parts/shipping/storage/sales was then established in Incline Village*.
The company has been mistakenly identified as originating in Incline Village NV.
Sugarman was asked to leave the company and Bonasso soon followed…with 20 other manufacturers there was some pretty fierce competition in this time period…survival of the fittest they say.
The ownership of the small amount of parts left in Incline Village and various ski area parking lots and bone-yards became an issue when the Austrian company’s “North American division” finally went bankrupt due to the aforementioned sales climate.
A “bankruptcy auction” was held with what was thought to be single bidder – that being being Heavenly Valley’s (trying to snag low cost replacement parts for his then new chairlifts) owner Hugh Killebrew…however Tony Sowder, Riblet Tramway’s owner won with the higher bid… much to Killebrew’s surprise.
Riblet Tramway made many aftermarket improvements to the SLI product, this association along with the bankruptcy “sale” is often attributed in history as Riblet buying SLI.
SLI still existed in Europe and sold parts to North American owners for a number of years until they went bankrupt.
Some SLI Peculiarities
In SLI’s final years in North America it was found that the profit margin was going to be quite slim or nonexistent – most chairlifts built that year were minus a tower – the “extra span” was spread among the remaining towers…you can still see the long spans in the original lifts still standing.
The bullwheel gage was narrower than the line gage…shipping issues I guess.
The sheave assemblies where quite large and did not flex – good for alignments but very difficult to rebuild or change because of the weight.
The carriers were touted a being maintenance free…they had galvanized stems and bails with fiberglass seat slats – no paint or stain needed.
The fiberglass slats were never strong enough, they needed constant changing or replacement with wood slats, so not really maintenance free after all.
The carriers were extremely light and very top heavy due to the light seat design, because of this they swing very easy in light winds. If you have ever ridden in a fixed quad chair (very bottom heavy) in the wind you can see the benefits of the design change.
Other stuff
Bonasso was long associated with the B-77 ropeway standards committee.

Sugarman in his younger years was a spy for the CIA (hence the European connection) and the marketing genius behind “blueblocker” sunglasses and was the original (before Bonasso) salesperson for SLI.

If I remember correctly, it was mentioned in SAM that Riblet did acquire SLI or it's American counterpart.

In addition, Sugar Bowl also had an SLI, the former Lincoln double.

Recently I spoke with another past Riblet employee who reconfirms the information given in the original post.
Most of the remaining SLI components that were awarded in the winning bid were installed as a single lift at 49 North ski area in 1980 (I believe this is Payday). This install is mentioned in 49 North’s history page. He also confirmed Riblet was never a sales agent for SLI but did modify existing SLI’s and sold old SLI line machinery (this was my experience also).
49 North resort location is about 49 miles north of Spokane Washington – Riblet was based out of Spokane.
