I literally JUST finished moving 40 machines up 19 total steps using my brand new Escalera - bought it with a spare battery so one battery could charge overnight

Took 2 full weekends and 4 weeknights to get them all up there but I did it on 3 full batteries!

Big thanks and shout out to Zach who took time with me on the phone as I asked about the 66" vs the 60" model - I bought the 60" and it works really well for me

Happy to answer any questions you all might have as I've now got some experience under my belt!
See the last few posts of my thread in the link below. Page #4 and #5 will give you the cliff notes version

Also built this one man lift so that once I got the game up in the room, I could quickly (and painlessly!) set it up - again, an invaluable tool!

No.
Unless climbing stairs (or deadlifting straight up if you buy the forklift style attachment), it's just a fancy (and insanely heavy) hand truck/appliance dolly

BUT ...

I would never be without one again!
Just this past year I have used my Escalera more than 50 trips up and down stairs

LOVE it and got mine from Zach too
