Energy Crisis
Screwjack Lift owners often complain...
"the battery died and I got stuck on the steps" |
The omminous recomendation above is from a ScrewJack lift owners manual.

| The ScrewJack Type lifts use a starter moter with NO gear reduction. They draw over 100 Amps in the up mode, and they draw over 50 amps in the down mode. Just a quick question... Where do you keep the "spare battery" they say you need. And how do you go get the battery when you are stuck on the steps? | Because they ScrewJack Lifts put such a drain on the battery, users often compalin about getting "stuck on the steps" A common story is that they had to get their car battery and jumper cables to get the ScrewJack off of the steps. i.e. "Screwjack Un-plugged" |

| Because of the energy efficient gearbox on the Escalera StairClimber, even with a totally dead battery although you may not have enough power to climb all the way UP the stairway, you will always have enough power to climb back DOWN the stairway. | Escalera Inc. does not reccomend a spare battery for their StairClimbers. You won't need one! The Escalera StairClimber gearbox has a 1/2 horsepower motor and a gearbox with a 200 to 1 gear reduction. |
