Engine hoist capacity
I am building an engine hoist framework, to hang a chainfall. I will be
using it to pull and install engines and trans in my racecar and other various vehicles. I planned on using 4x4's for the uprights and the top crossboard. The crossboard, that the chainfall will hang from, will be 10' long. Is a 4x4 strong enough, or should I use a 4x6, or something else entirely? I figure the engine/trans combos shouldn't be more than 700 or 800#. Plus maybe a momentary higher weight when a mount hangs up, and the front of the car lifts up a little with the engine. Any comments/thoughts are appreciated! Thanks, Big E |

If M = WL/8 = 100L and S = M/1000 and 3.5 = sqart(6S/3.5), L = 71" max, approximately. Yes. :) But OP said 10-ft span which would be stretching it by quite a bunch... I'm w/ the suggestion on looking at alternatives including biting the bullet and buying a decent-sized beam--amongst other things, would allow the hoist to be tracked, always a useful enhancement. If use lumber, would suggest 2-3 2x8 or -10s minimum, but that's simply a "feels about right" sizing, I didn't even estimate a stress number... -- |

I'd imagine if you work on 4x4s you could conceivably pull an engine, automatic transmission, and transfer case as a unit, which even with a modern, lightweight engine and trans case could weigh over 1000# all up. like Bob says, you don't want to find out that you underbuilt the hard way. nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

Stuff That Can Kill You is not the place to cut corners. Used engine lifts are not that hard to find or expensive, compared to the doctor bills if you drop it on your foot, or the funeral bills if you drop it on your head or chest. aem sends... |

Thanks, Big E I would not lift anything that heavy with wood. I know it has been done, and is currently done. However, there is a safety factor here, and the failures are catastrophic. OSHA rules forbid lifting ANYTHING with rope in their rigging regulations. In the field, it is done ALL THE TIME, and done safely by people who know rope, knots, practices. Timber hitch is a common example. Works better and safer than a chain or sling, but they don't want you to use it. If the wooden beam is all you have to work with, put two vertical support members to help distribute the load and make it a little safer. Steve |

1) If you have a large Oak tree - hoist the engine from the largest branch. Even then you can never tell. I have several 70' oak trees and one had a nearly horizontal branch up about 20 feet. The branch was a good 10" thick. Many times I pondered how I could get some ropes up there for a swing for the grandkids. One hot summer about 3 years ago, I was walking in the back yard and heard a tremendous splitting noise, and the entire branch hit the ground with a crash. -- Dennis |

To elaborate a little on my original idea... I was thinking 4x4
uprights, with a 4x4 or 4x6 top crossbar. I was going to run 2x4's diagonally from almost the middle of the crossbar, to the uprights, 2 per side. I figured this would beef up the middle of the crossbar, where the chainfall would go. By the way, I'm going to use a chain chainfall, where you pull the chain one way for up and the other for down, not ropes or pulleys. I was going to use 4x4's on the bottom, under the uprights, with 3 swivel casters per side, for mobility. I wanted to be able to disasemble it for storage, as it is not something to use everyday. I know a small block chevy is a little under 500#, and probably another 200# for a tranny. I wanted a 10' span on top, to give plenty of room to work on the sides of the car, but as our latemodel racecar is about 6 1/2' wide, I could go less if I had to. I have a cheap, foldup Harbor Freight cherrypicker now, but it is marginal in reach and height to pull many motors. I just want something I can use safely, inside my garage because it gets cold here in Michigan in the winter. So what if I go 8' span, with my diagonals, possibly either stack 2 4x4's, or use a bundle of 2 or 3 2x8's or 2x10's? Or is wood just going to be too weak no matter how I do it? I really appreciate the input! Big E |

I've deleted the previous posts, hence posting here. The way to go for me is an hydraulic lift on a mobile frame. I bought one probably 25 yrs ago that has lifted out and in many separate and combined units in safety. At the time, it costed me about $200 so more now but not that much and worth it! |

I don't have a way to post pics, but my garage is 26' wide, 38' deep,
12' tall ceiling. The front rollup door is 16' wide, and 10' tall. I have an apron in front of the garage 25' out, the full width of the garage. ( the apron and the garage floor are concrete ) I thought this setup could be used inside during bad weather, and rolled outside, or near the door on nice days when I want to work in the fresh air.

Engine hoist capacity/webtv rant
My first dealings with the internet, about 10 years ago, was with webtv.
Simple, no viruses, good for basic e-mail and posting. Since then, my wife got a computer, and since she has service from MSN, I get free webtv service. So while she does the internet thing on hers, I just play around on this, since I have it and it's free. I'm not much into "technology", in fact I just got a cellphone about a year ago. (mostly because it was given to me from a co-worker who was upgrading, and it is a virgin mobile for $6.99/month and 10 cents/minute. And I only use maybe 10 minutes a month at most) As far as the racing, our families have been it for decades. We've ran everything from demo derbies to enduros, ministocks to latemodels. My wife, in 2003 won the track championship, first female ever, at our local paved flat 1/4 mile track. We both have multiple top 5 and top 10 point finishes in various classes. Her current car is a latemodel, 13-1 compression, ford 9 inch, mini clutch, ect. Sorry for the rant, but I take offence when people assume that every person with webtv is a moron. (many ARE, but that is beside the point! lol) Thanks for all the suggestions, I'm still deciding what way to go on this project. I'll let everyone know what I do, with results when I do. Big E |

What puzzles me is if you're into the racing in such a big way you would even consider anything but a well-built hoist. You surely must be able to and have all the welding equipment you would need and a little contemplation and design would allow for a quick set up and take down assembly using pins, etc., and provide more than adequate strength w/ less bulky support, etc., in the way... $0.02, imo, ymmv, etc., etc., etc., ... -- |

Engine hoist capacity/webtv rant
Well, a prebuilt gantry hoist runs $500-600. The steel to build one,
with the prices of even scrapmetal thru the roof, wouldn't be cheap. I just had my garage built in the fall, and the package, for some reason, had some extra lumber. I've got a couple of long 4x4's, and some cutoff pieces 5' long or so. Also several 2x8's, and various 2x4 pieces. So if I could safely build a hoist with this, it would be almost free, other than my time. Then I could spend more on go fast parts! lol Really, I honestly thought that I could build a wooden hoist that would be much heavier duty than a store-bought hoist.I have a large, very heavily built outside hoist I made to lift car bodies off the frame. It is made from 6x6's, with tons of bracing, but it is too tall to go in the garage, and there is no way to take it apart. I have a good, heavy duty steel hydrualic cherrypicker at my father-in-laws garage, but he uses it quite a bit on our fleet so I don't want to take it from him. Also, our latemodel has a fairly long nose, sitting low to the ground, with a bit of engine setback. So even my good picker is stretching to do this motor. I figured that an overhead lifting hoist would work better on this car in particular. Maybe my original idea won't work, thats why I was looking for imput. My drawing board is always open! Big E |
