An Enormous Piece of Concrete

This is the top of the old Pallavicini Lift. Everything you see here was below ground. The vertical pipe is about 8 feet tall. There was an additional 8 feet of pipe that has already been removed. The bullwheel rested on top of that. The pipe is full of concrete and it is embedded in a concrete mass approximately 10' x 20' x 5'. That is huge. The top of a chairlift has to be incredibly heavy to keep it from being pulled down the hill. Between the weight of the chairlift and the motor that drives the lift, there are tremendous forces at work. We will be breaking this concrete chunk apart. The Leitner Poma guys will replace it with a new foundation of comparable size.

Out of curiosity, how extensive are the foundations on the poles in between the top and bottom?

By my calculations that is 150,000 pounds of concrete in the base. Wow!!

Not small either. Leitner-Poma (I’m not familiar with Doppelmayr, but they’re probably similar) pours a 12’x12’x8’ or thereabouts footer, with a 4’x4’x4’ pedestal in too of that for the tower base. Big towers might be 4’x6’x6’ for the pedestal. All numbers are eyeball estimates from being peripherally involved.

WOW. Unfortunately I have considerable experience at removing much less robust concrete. That job is tough! Great info Mr. Al.
