I'm sure this page is abandoned at this time, but just wanted to let you know, just had one of the hardest elevators rescue in my career, elevator wouldnt reset, door release was broken, like literally nothing worked and ended up using your pole method and worked like a charm. So thx
From a retired lifelong lift engineer in London…this is all good sound advice for the Fire & Rescue point of view. Some of the terminology sounds unfamiliar but perhaps that’s just local. The “halfway cables” , the electrical connections hanging in a loop to the car, are travelling cables we sometimes refer to as flexes. The fixed end is generally at a point that’s halfway up the hoist way/lift shaft. The stop switch or button will cut a safety circuit to stop normal operation. That’s not shutting off the main power. If you get into any of the electrics there will be live power there. Looking for the machine room can be a nightmare for a hydraulic lift. Looking to see where the pipe goes is a good first clue. With hydraulics, anywhere the pipe and electrical connections can go is possible! I’ve even found a machine room in a cellar in a building next door. Be extra wary of getting under a hydraulic lift. There’s only that contained oil holding it up. Any damage to that pipe system and it WILL come down. Even if the main power is locked off. Most of the hydraulics that I’ve installed or worked on have had a valve for slow draining oil back into the tank to lower the car. Beware, that will override any electrical safety switch and getting the car up again is a whole new ball game. Think of it as a one way…until an engineer can get the lift running again.
Let suggest an extra step to make it super safe. What you have take bend the hose at ftwo o’clock and bring the tail back around the hydrant counter clock wise till the brass is at 6 o’clock. Them at 10 o’clock put your boot against the hose and the hydrant. If you get a snag the hose will slip away. FYI the man outlet is 6 o’clock.
You can order a 4' D- handle NY hook from Fire Hooks Unlimited..and a few of their distributors. I use a Bulldog HRD (Halligan Retention Device) on it as well. It's basically the old chain link halligan marrying method, but removable. It's a clamp on style that attaches with screws. Super nice if you don't have welding skills..and it holds great. Like they said.. A 4' hook and halligan will do all of the work you could possibly need, as an engine at least, on a residential fire. We started using it primarily for garden style apartments. Our nozzleman will take the married set along with a hose bundle. That way the first due engine has everything they need for FE, initial fire attack, and checking for extension.
Elevator shafts are cool, but they are dangerous so be very careful. Do not attempt to play with them without permission or something because you can get hurt really bad always use caution.
I shut off the power supply and then couldn't get it turned back on.... please cover this problem... is there a safety latch? I pushed as hard as I could and couldn't get it back on.... so then the elevator repair people complained that I had tampered with their equipment and charged even more than usual because I turned the power to do a reset as described above. Couldn't get the power box turned back on.... Help ?
freight elevators are really cool though because they have automatic vertical doors unlike a passenger elevator which typically has the automatic sliding ones
Ill be honest if I was to get a job like that Id actually bring one of those headlamps that you strap on your head because that would make things millions of times easier because you now got both hands free one to hold on to something and the other for actual operations
The general public does not need to use or be in possession of elevator door keys , speaking as a retired elevator mechanic state elevator inspector, also a violation of ASME code.
That was an elevator mechanic for 34 years you do not have to worry about attraction elevator going down there is a greater chance of the elevator crashing going up from faulty brake it happens many times
Also firefighters should know the difference between an elevator geared machine in an elevator gearless machine it is very very very very very very very very dangerous if you pick the brake on a gearless machine at elevator cable take off in the up direction and you will not be able to stop it not be able to stop it it will crash into the overhead it's happened many times
Exactly. So my biggest question is how extensive is their training? Is IUEC/NEIEP involved with their training? Because that sht wouldn't fly within the elevator industry.
I've been working on elevators for 34 years elevators if you release the brake on a geared machine and the elevator cab is empty with no load the elevator will go in the up Direction because a counterbalance weight is 40% heavier than the car
exactly and most people dont realize this they think when the brakes fail that an elevator will go down the shaft but the counterweight is there to balance the load out so the motor is only doing like 50% of the work
Not only geared machines. A gearless machine will also run when the brake is released and it will also run more freely because it doesn’t have to push back through that worm gear. Whatever the machine, it all depends on the amount of load in the car.
Ill be honest if I was to install an elevator in a building which I cant because I dont have a building and elevators are way too expensive but Id go with a traction because hydraulic elevators use oil and oil is getting more expensive nowadays but traction ones dont use as much oil and would save money for paying the elevator bill
Great video. I carried extra gloves leather and latex. I learned from my training with Chicago FD, I carried a switchblade knife not for protection but in case we became entangled in wires. A large piece of chalk a collapsible Spanner wrench wooden wedges and a small flashlight that fit in the palm of my hand.
Melbourne Australia. We discarded smooth bores for automatics back in the 1990s. Modern pumps can easily supply whatever pressure will give 100 psi (converting from metric in my head) at the branch. Modern autos can do everything a smooth bore can and a lot that they can't. For internal structure firefighting, I cannot fathom why one would use anything else.
That would be scary being in the elevator pit and the car came down trapping you under! They should have trap doors in the floor or lower wall so that if you do find yourself stuck or have to access the pit when the elevator is on the ground floor, you can still escape or get in.
For automatic doors yes, motors and limits are powered separately...(typically) Locks go to normal elevator control. Not mentioned are manual door freight. Similar locks but no motors and associated equipment.
The motor/pump is in the machine room. A drive cylinder each side is usually for heavier loads and/or a larger lift. That could be passenger or freight.
I am dumbfounded that this set of videos does not have more views or comments. I have 30 years of service in a fire department and have not come across better information. I hope more guys stumble upon these valuable videos. Well done.
Will an elevator self correct for drift if in fire service mode? Or will it be allowed to drift uncorrected all the way to the basement limit springs.?
AWESOME instruction. I’m writing this in March of 2023. There’s already increased citizen interest in becoming more capable in dangerous/ high stress situations. This type of information will be more sought after. In 2014 I was accidentally abandoned in a cargo container stacked atop another cargo container. Stranded 9 feet above asphalt and I couldn’t slowly lower myself against the bottom containers doors because they were open too. I carried a load rated climbing biner at the time with my Leatherman & Surefire attached to a belt loop. There was substantial mule tape in the cargo container, securing the load. All cargo containers have two welded pick points at the bottom corners of the door jam. I rigged the mule tape like rope and using my one biner, I self rescued. Gave my colleagues an earful for forgetting me up there. This happened on a Disney kids show. We stored props in the C containers. My only question with the Haligan anchor? Is the firefighter able to retrieve the tool once the burn is under control or is it a $700 loss?
generally after overhaul you can get the halligan back. Its made of iron so chances are it wont melt or be destroyed. If you dont find it you will not get in trouble its simply a loss
Today I watched this video. I must say that all hose loads have their benefits/ risk/drawbacks. I personally believe that the flat load with loops is still probably the best and safest load of all. True large diameter hose( 4, 5 and 6 inch) should just be loaded without loops. This is all just my personal opinion. Hav a good day and stay safe. Retired Captain from another career department
