|
|
At some point I'll be putting a lift in my shop. Considering doing the job myself with helpers. I have plenty of room up top and side to side, with good concrete floor. I've been reading up on the topic, wanted to know if anyone here has tackled that job, has any suggestions. The lift I have in mind has overhead "bridge" for plumbing/cables. Floor is clear. Thanks for any advice, Gary in Maryland. |

Just make sure your concrete floor is thick enough. We put in a small swinging crane(300LB) and had to go down 18 inches for a base. |

I have a Bendpak two post lift. It requires 4 inches of concrete and 12 feet of ceiling height. The posts are heavy, especially with the carriages inside them, which have to be put inside the posts while they are laying horizontal. I would think you would want a minimum of 3 guys helping with the install, preferably 4. Mine was installed by Bendpak's installer. I watched them do the install. I would tackle the cable setup after watching them, but it can be complicated if you've not been around lifts very much.
Don't drill the holes in your concrete until you have the post standing where you want it. |

Thanks, There is also the possibility I'll have the pros do the installation. I like to know about any technical issues ahead of time and be able to talk to the installers somewhat intelligently. The four inch concrete base is the minimum thickness from my reading on the subject. |

Four inches of chalky old concrete is not enough, 4 inches of crisp old concrete or reinforced or Fiber mesh concrete is fine.
Position the lift so the vehicles can be placed at or near their center of gravity (take the load out of the bed!!!) Jim |

I would be worried that a two post lift would require much more concrete than the average floor has, unless you hit a beam. |

I put one in this spring. I got the type with the cables and hoses going through a plate on the floor because I wanted a clear span above (I wanted to be sure it would clear my
full size van). I have a 5" floor with a huge amount of re-rod. Amazing I didn't hit one when drilling the holes. Just for the hell of it I put bracing angle iron from the tops
of the posts to the side framework of my building. The uprights were too heavy to even drag across the floor. Lifted them with the bucket loader onto car dollies then pulled
them upright with a block and tackle attached to roof beams. Once upright they can be walked into place. Watched a video on how to install the posts and they recommended
construction epoxy in the holes. They said to fill the holes 2/3 with epoxy (I found 1/3 is plenty). Learned the hard way to put a rag around the bolt before pounding them into
place so as not to take an epoxy bath. Let the epoxy harden overnight and the next day the bolts tighten up without moving. I think the bolt torque was something like 130 lbs
and my arms were a couple of inches longer after doing the job. The important thing is, since you are reading this you already own a tractor, being able to unload it from the
shipping truck.

I've installed two of them,just follow the instructions and they go real easy,the first one we used my loader tractor to stand the post up,the second one 4 of us
stood them up after we put them in place with a bobcat.Lay everything out on the concrete with chalk lines and make sure the columns are level both
directions,both ours had the overhead cables and hyds. We anchored the control post and stood the second one up and supported it while we fastened the top rail to
it,then leveled the second post and anchored it (just to double check our dims.)they both came out real close to the chalk marks.It's really very simple to do
with a couple of buddy's helping.I wired mine with conduit pulled wires for a welding outlet and a 110 outlet on the control post,one of the smartest things I
ever did,use both of them a lot!As stated by others just make sure the concrete is 4 inches or more and you're good to go. Have fun with it,wish I would have put
mine in 35 years ago when I bought the place. |

Thanks for the replies, nice-looking lift and good installation. Yes, I have loader tractor, should handle the heavy stuff no problem. Curious about the epoxy:
"Let the epoxy harden overnight and the next day the bolts tighten up without moving. I think the bolt torque was something like 130 lbs"
Was it JUST epoxy in the holes with the bolts, or did you use an anchor of some kind for the bolts to screw into? Probably different ways to do this, just wondering how it worked with the epoxy. |

The bolts that came with the lift are the "expanding" anchor type but I found they can continue to slip as they are being tightened and the top winds up being higher out of the
hole than is called for in the instructions (dangerous, can pull out). With the epoxy they don't move AT ALL. |

One other thing; The epoxy manufacturers have it figured out pretty good. You'll run out of the tube just as you have 2 bolts to go. |

The two post lift in my shop has a heavy length of angle iron to spread the load at the beam base on each beam. If I recall the floor is five inch with re-enforcement wire when it was poured in 1992. |

Ok, thanks. Just watched a video and I have a better understanding of how the epoxy works. Will make sure to get two tubes if I go that way LOL  |

The torque on my anchor bolts are 60 maybe 80 no were near 130
My son and I have put up 12 are so nuttin to it, I ordered mine 2' taller than normal clear floor type its the only way to fly... The last three I brought in 2002 were Worth they are a very strong well built lift made in the USA... What do you plan to lift if its more than a 1/2 ton truck I would go at the least 12K I have a 12K wished I had got a 15K... I still have the first one I brought its a Mohawk
A-7 I brought it around 1985 they were 5K with a lifetime warranty. |

Do these use a cable over hydraulic or chain over hydraulic?? If they are cable operated and you see any
fraying of the cable -- the cable needs to be replaced immiediatly. They used to run around $1200.00 for the
cables. |
