Hoists

hi i am removing an old single post air drive hydraulic lift/hoist and was wondering the best way to remove it. i do have access to plenty of tools and i have some one helping me. i would appreciate fast responses because we are starting on saturday. thank you

Great answers, and yeah that sucker IS HEAVY. LOL nobody mentioned that it’s actually not hydraulic though. It’s pneumatic, it goes up by compressed air. Guess that don’t matter too much. Be glad it’s not hydraulic. You know how much oil that thing would need? Wow, and that size it would lift an entire building. Those older things are not the safest, true, but you have to get rid of it? LOL wish I had one of those older ones in my garage for certain applications.

Maybe you could sell it to a barber shop that does really heavy people. No? LOL
Use an impact gun when you take off those old bolts, and I would use something quite a bit heavier duty than uh lets just say a bobcat wouldn’t be safe. Payloader should do the tricck with some good chain. You having pizza afterwards then let me know I’ll be there (for the pizza) LOL see ya good luck

I cant come to a final conclusion. I got both cars (two 91 MR2s) for my engine swap but now I need tools. What do I absolutely need to be able to successfully complete the engine swap? Besides Engine Hoist, what else?

just when you think you have them all you’re always going to be missing something but wrenches metric and american screwdrivers flathead and phillips / straight sockets amer/met ratchet and extensions pry bars/ pliers /universal sockets 3/8 drive and 1/2 inch drive on all sockets and ratchets and extensions

A 400 Kg. mine car is hoisted up an incline of 28.07 degrees using a cable and motor M. For a short time, the force in the cable is F=(3200t^2) N, where t is in seconds. If the car has an initial velocity V0=2m/s at s=0 and t=0, determine the distance it moves up the plane when t=2 seconds.

There are 2 forces acting on a car along the incline: F upward and component of gravity mgsin(28.07) downward. Total force is F - mgsin(28.07) and according to second law acceleration is a = (F - mgsin(28.07))/m = F/m - gsin(28.07) = 3200/m*t^2 - gsin(28.07)
To find velocity at time t we have to find integral of a:
v = 3200/(3m)*t^3 - gsin(28.07)*t + v0
To find displacement we have to find integral of v:
d = 3200/(12m)*t^4 - gsin(28.07)/2*t^2 + v0*t

I’m trying to determine the word (frustration, stress, irritability) that describes the situation when you can’t get things done because of a chain of broken or overly-complicated circumstances. And when you annotate the reasons for not being able to move forward it sounds like you are complaining but the fact is that nothing is working.

For exmple, if I wanted to change the tire on my car, but I can’t find my tire jack, or if I find my tire jack, but part of it has been borrowed by my neighbor, who is on vacation and the person who is house sitting doesn’t speak English. Or I finally do get the car jack but it is broken. Or I manage to fix the broken car jack and get the Car Hoisted but now find out that the spare tire is flat too. Is there a general term that one could use to describe these types of annoyances?

is it Murphy’s Law? I’m not entirely sure
