How to remove a 300Ft. Chimney.

[-3Doc]

This is a job I was involved in, we had to remove a 300ft chimney without disturbing the working pulp mill below.
My job was to plumb and wire a concrete cruncher to a 300 komatsu excavator and hang the cruncher on a 325' crane and control the cruncher from a man basket hanging from another crane.
The chimney was then chewed from the top down sending all the material down the center of the chimney and removed out the bottom through a cleanout. Was a fun job!:canada

Nice

I remember pictures from another stack about as tall with a complete excavator held up by a crane doing the demo work.

Here is the thread: https://www.heavyequipmentforums.com/Forum/showthread.php?t=3046&highlight=excavator+crane

Interesting to see different ways of getting the job done. Looks like they both worked out.

Always interesting to see new ways of getting structures down.

We had a similar job last year (ca 150m tall chimney). Then we used a modified brokk, working as a reversed slipform. The debris was chipped into the chimney and taken out in the bottom. The last 33m was demolished with an UHD.

Fred Dibnah

A most talented individual who could turn his hand to anything including a tv career spanning 30+ years,Fred was the most natural presenter who's enthusiasm for his craft as a steeple jack was overwhelming ,but his abilities as an engineer were beyond question .
His use of Victorian methods in his steam engines were a joy to watch,in his yard at the back of his house was a steam powered work shop and one of his final projects was to build a victorian mine form equipment he had salvaged ,in fact most of his home and shop were constructed from salvaged materials from his career as a steeple jack.
The programmed he made well were as "common as muck "and made so as even a person who had no grasp of machinery would understand it and people like us would be watching the other dozen things going on in the backround.

Sadly Fred is no longer with us taken prematurely by cancer but his last series was a tour of England in a steam roller with his son and a colleague columinatiing in his visit to Buckingham palace to be awarded an MBE.He will be sadly missed.

Fred Dibnah MBE (28 April 1938 – 6 November 2004), born in Bolton, Lancashire, was an English steeplejack, engineer and eccentric who became a television personality, a cult figure and, latterly, a national institution.

This job was done about 10 years ago and it was a fun but challenging job to do!
The hoses from the machine to the crusher were about 350' long and there were four hoses and one electrical line that went to the man basket. There was about 25 gallons of extra oil that just stayed in the hoses when we were done, hoses were plugged and caped and stored for next time.:canada
