Quoted from hoby1:
The factory switches are rated at 50amp which is what the motor draw is ... Wont that be an issue in the near future with the switch going bad
The one you are referring too is only 20 amp
I initially was perplexed about the same thing.
I matched the specs of the new switch to the faulty switch that was in there, and verified that it was likely the oem switch, by comparing the specs to replacements from WESCO. It was used daily, for YEARS, without a problem, by an HVAC contractor buddy of mine prior to me getting it. I think it is because the Stairking has an automotive in-line thermal breaker that protects everything from overheating. I recently used it to move a safe up from a 20 stair, 10-foot ceiling basement, and it worked great.
I've had both Staircats, and Stairkings, and functionally, they are the same. I now prefer the Stairking as the main frame seems a little sturdier and doesn't flex as much, if at all, and the whole unit is lighter than the Stairkat (by a smidge). After refurbishing a number of both over the years, it's surprising how much they cost new, considering the components, but what's cheaper? A blown back, or a stairclimber? I'll go with the latter, every time.
These things are great, and take up very little space when being stored. And the parts are easy to find and replace, even on old units, as everything is off-the-shelf industrial grade parts except the proprietary frames each manufacturer uses.
But to keep this discussion on track, back to Escalera talk, haha.
