We use what is called a skidding system for moving heavy (100 ton range) transformers off of trailers and onto foundations in substations.
This is a similar concept but different design: http://www.enerpac.com/en/heavy-lifting-technology/skidding-system
Ours is essentially 2 rails made from...
When bidding small fabrications, I often am asked to quote simple beams, usually with a single centered point load or two point loads (both symmetrical and asymmetrical), sometimes with a column on each end (I haven't seen us do any jobs with a midspan column). Conceptually, they usually are...
Per Metengr's suggestion, I'm crossposting this from the welding forum: (original thread: here
I was viewing a job with one of our estimators. We are installing large metal hanging brackets to a block wall. In the middle of the wall span is a large column that supports the roof, a 2nd floor...
I was viewing a job today with one of our estimators. We are installing large metal hanging brackets to a block wall. In the middle of the wall span is a large column that supports the roof, a 2nd floor deck, and on the side we're working on there's also a large stool welded to support that...
I'm scratching my head (since I'm just a dumb construction worker ;) and figured maybe someone here could come up with a brilliant idea that I'm overlooking.
Background:
We have a large skidding system; essentially it's two heavy steel beams fully reinforced with two inverted channels (picture...
I've gone over D1.1 a few times, talked with a CWI friend, and talked with one of the members of the AWS D1 committee who used to be my instructor, in regards to this question and I've gotten different responses from both parties and nothing that I can find is concrete in the standard to support...
I've got a copy of ACAD 2010 and I just received a bunch of drawings from another company (somewhere around 10 drawings). In them, they have *all* the dimensions and text blocks (MText) set to yellow. The dimension lines are green but the text is yellow. If I print this in color, you can't read...
This is probably a basic question but my experience lies outside of FEA. In its most basic form, the object we're analyzing is effectively a table. 4 legs, object weight roughly centered between them. In real life, the object will sit on the floor, not anchored or otherwise restrained. Is it...
