Quoted from beefzap:The only concern I have: Are there any safety issues using this? With one person pulling and one spotting, if there is a failure (battery, slippage on the carpet, something breaks) what can happen? I have not heard of anyone getting hurt, but just curious.
Thanks
well.. it's moving nearly 400lbs of stuff.. there is always some element of safety in question
The biggest issue people have with Escaleras is getting used to the lurching when the climbing feet push off the step at the start of each cycle. This is not difficult, it just takes getting used to.. the load will pull away from you while climbing steps momentarily at the start of each step as the load shifts. The more angled the load is, the less this lurching will hinder you (as your center of gravity will be further back).
The second biggest risk is coming off the step because the foot slipped or was not fully on the step in the first place. If this were to happen, the biggest problem is the weight moving/pulling on you and controlling it vs having it rip out of your hands. The cart would likely just fall back to the lower step, so only dropping like 8".. which is not a huge deal. The problem is the lack of control which could lead to a runaway. This you minimize by 1) ensuring you are all the way back against a step (technique) and 2) if there is concern about the step shapes/materials.. test run first. You'll find going down harder than up for this reason of finding the edge... but don't fear... if you are short, the cart can go down like a normal appliance cart on runners. Going TOO far really is the main concern (this is what the step edge detect add-on aides).
Coming off the step is really the primary risk, but it should not happen unless you are doing really sketchy things or are haphazard. Safety would tell you, if this happens, sacrifice the load, not yourself... and don't have people below the load.
For that reason, you really don't need/want someone pushing because you never want anyone underneath your load. Inexperienced people will find a second person helpful because of the extra set of eyes to see where you are on steps and to provide some aid (from the side!) if the lurching were to catch you off guard. The second person is really a comfort factor, they don't help much for the actual work portion.
Battery won't fail except run out of juice.. and that you know long before it goes to zero. Then it's more of a heavy appliance cart
The lifting chains are beefy... the climbing feet do wear out over time.. replace the rubber feet when they start breaking up.
I move games all the time by myself with mine... I only really need a second person more for what I call 'tilt patrol' to make sure the load doesn't tip over sideways when going through the uneven yard. When it comes to climbing... they don't add anything once you are familiar with how the tool operates.
Just run it up and down your steps without a load to get used to it. You might have issues with dirt/grease on the carpet steps depending on the carpet material. you might find the stick-on plastic runner construction crews use helpful.
