EDIT: Oops I remembered I read it does extend, you are using the globe for that and the van door for your arm Sorry, sleepy. Still curious about the reduction and 80/20 stuff though  |
I'm pretty sure the reduction we have on the lifting sprockets works out to 24 to 1...but I'm not entirely sure...give me a chance tomorrow and I'll know for sure. At any rate, it moves fast enough to cap in about 5 seconds and has enough power to lift 150 lbs easily. And yes, it does telescope
