You must find that post and share it! OMG, the things people will attempt!!
Reminds me on the episode of Alaska the Last Frontier, when Otto Kilchner kept going for bigger with just about every kind of thing that he could use as an explosive, to take out a stump. Not something you do on your own.

How is Daniel's disrespectful when it was the truth. The guy is a licensed engineer and knows what he is talking about.

Unbuilding a Elevator is not something that you just jump in and do. The last thing that happens when an elevator is finished, is raising the counter weights to a specific height, so that they act to help the motor run as spec'd for the max weight of the elevator.

Go talk to a company that works on elevators and they will even tell you to let them handle it and take away the materials. They have the experience in this area and have years of knowledge in knowing how easy the failure or improper dismantling of the mechanical's can kill you if you are not paying attention.

Re: Removing an old elevator with balancing weights


Just for the information that the people on here seem to think it's to big of a job for the average person, I did it, it's done, and i did have to pay to have a company or engineer give me input that had no idea on the job I was doing. Thank you to the guys with "helpfull" information. Basically the motor holds the weights in place when the chains are cut, then lowering the weights to the bottom. I didn't need a degree in engineering to figure it out. But is anyone needs any info on one if it's similar I can give you the steps. Also for clarification, I made 2500 and 100 for metal to remove it. Hince the reason I wasn't calling someone else to do it......

Re: Removing an old elevator with balancing weights


The counterweight stack weighs more than the empty elevator car (and less than the elevator car fully loaded).

The car can be moved all the way up (and the weights brought all the way down) and most of the weights removed from the stack.

Depending on the exact weight balancing and car braking, the last few weights might have to be removed from the fully raised position (with the car lowered all the way).

Re: Removing an old elevator with balancing weights


Sometimes you gotta just say, what the heck, and go for it.

I repaired an old freight elevator a few years ago, in an early 1900's building that formerly housed a buggy builder, lumber company, a chevy dealer from the 40's to the early 60's, a furniture store up to the early 80's and then home base for a commercial building contractor until we purchased it in 2000.

My grandfather had told me about buying a car at the dealership after returning home from WW2, picking it out on the second floor and watching as they brought it down on the elevator. I can clearly remember going to the basement and picking out a gas range in the mid 70's when I was about 8, then riding up with it on the old elevator. Stands out in my mind i guess because of the elevator ride and it's the only NEW appliance I can ever remember my grandpa buying.

The counterweight cable broke, while I was taking a 4000 lb trailer down to the basement! That was fairly exciting for just a couple seconds, glad it was pretty dark or probably would have been a lot more scary. Called around to a few elevator places and imagine that, nobody would even look at a thing like that; even though it had been used as is for over 100 years. The only way they would touch it; would have to be completely modernized with all the current safety equipment and meet all current regulations. That would have basically meant ripping it out and completely replacing it, probably would have cost more than we gave for the whole building. Meanwhile, with thousands upon thousands of pounds of equipment and supplies stored in the 16,000 square feet of second floor and basement space, fixing it absolutely had to happen.

The lift motor was able to easily lift the empty car way up to the second floor without having the counterweight connected. Once lifted up I installed the new, proper elevator cable and even bought brand new elevator cable hardware that was identical to the old hardware I had. Only had to lift the counterweight about a foot or so off the basement floor level using a chain hoist, then wrapped and threaded the new cable and installed the anchor end. Works good as new and been in use a few years since the repair.
