It's hard to see but this is a bit of truly brilliant thinking. It only took one man to deliver a new gas water heater to our home. The steel dolly used to move the heater had a small motor and a sliding bottom platform that descended down a central track at the push of button. No need to bump the dolly down the stairs.
The platform, driven by the small motor, can be extended five feet to where it is stabilized on a lower step. Then the movement is reversed and the extended dolly collapsed. At this point the dolly is again slanted back and the platform descends again taking the heater to a new and much lower step. The operation as repeated until the water heater reaches the basement floor.
The old heater is removed the same way. No wear and tear on the home. No tearing of the carpeting. Very little strain on the installer. Brilliant.
When we think of urban life, we don't always consider the support staff. Folk like this hot water tank installer are important and if they are very productive all the better. This dolly clearly makes this man a far more productive worker. Unfortunately, it also puts one person out of a job. The last heater installation required two delivery folk.

Clever and very useful. Somewhere I have a photo of my old neighborhood in Montmartre of a truck delivering a washing mashine to an older, elevator-less. Building. The delivery truck was like a fire truck with a loooong ladder and platform holding, very securely I might add, the washing machine that was delivered through the recipient's window.
