Aerial Trams

Last year we visited the Historical Museum in Silverton, Colorado. Among the many interesting exhibits was a display dealing with aerial trams.

These aerial trams were used to transport ores down from the mines to the mill and supplies back to the mines by the use of miles of steel cables over the mountain. These trams made transportation of ores feasible over the inhospitable terrain and deep snows much of the year. 

I found this fascinating and acquired books describing how the various systems were created, marketed, installed, operated and maintained. This education made me want to see a system in person.

This led us to the Mayflower Mill outside of Silverton, Colorado which is now a part of the Historical Society. It has an aerial tram house that is still intact. We explored that structure and then went four wheeling up Arrasta Gulch to study the aerial tram towers and understand how they worked.

This structure was part of the tram with a weight being used to maintain tension on the tram cables

The upper set of wheels rode on the upper of two cables. The lower cable was used to move the bucket along at about 5 MPH. A clamp was used to affix the bucket to the moving cable.

This is the oiler that was sent over the tram system once a month to lubricate the cable

The system was also used to transport miners

The miners rode to and from the mine in the ore cars. The company provided blankets to keep them warm

These towers were used to support the cable, change angle of the cable run and direction of the cable

When the mill closed the buckets stopped where they were and remain to this day


All in all a nice way to spend a day exploring the mountains

  1. That is a fascinating mill. A lot of stuff in a very small area. Surprised you didn't make it there last year.

  2. This is amazing! Those miners give new meaning to "rough commute" (to work)! I'm so glad you saw this operation and I am pleased that it is being preserved!
