When is an I-Beam not really an “I” Beam? While it’s common to use the generic term “I-Beam” for any beam with an I shape section, there are actually variations with different letter designations. And, there are advantages for the various shapes
I love seeing failures. Not that anyone wants things to fail, of course, we always try to make things that last. However, when a failure pops up, I love to look it over and understand the “how” and the “why”. It’s an excellent opportunity for learning, and I love to learn.
As a simplistic introduction to beam loading, this article discusses the complications in calculating stresses and deflection. While it’s pretty easy to calculate beam loading for simple theoretical cases, very few beams are actually simple. A trailer frame, for instance,
Every once in a while something unique catches my eye. This time it’s a low profile trailer suspension that does much the same as torsion axles — but in a way to allow tandem axle load sharing. As I’ve looked at it more, there are some really interesting advantages
There is some disagreement in trailer building about how to weld-on trailer spring brackets (also known as spring hangers). Some of you have sent questions about which techniques are best, especially
Do you need to weigh something really heavy but don’t have access to an industrial scale? How can I weigh heavy things — like a trailer frame — without a special super heavy duty scale?
Sometimes I wish my trailer was longer. Is there an easy way to make a trailer longer? Is that even possible? And, what are the limits
How long should a trailer tongue be? Is there a standard or is it totally arbitrary? Let’s get some answers on this fun trailer tongue length topic.
Nothing ruins a pleasant day quite like a goose egg on your head, or a throbbing finger pinch. Avoiding those things (and, of course, the much more disastrous potential events) is the context of this gantry crane safety article.
I have a great trailer, but it feels a bit flexy, maybe even rickety . . . How can I strengthen a trailer frame? How can I stiffen it?
Trailer axle position? This is a good question. Unfortunately, there is some popular, but misleading information around. So, how do you know proper trailer axle position? Here’s the whole answer,
Should you twist trailer safety chains to make them shorter? Certainly twisting them reduces the length so they don’t drag the ground. That part is good. However, there are big issues with twisting safety chains?
Do they accomplish the intended purpose? Or are trailer safety chains just a legal pain in the rear? Maybe the better question to ask, since we’re required to use them: “How do we make chains effective?“
In the debate about Steel or Aluminum for beams of trailer frames and gantry cranes, there is one piece we hear less about. An important part of the equation, for sure, is the property of Elasticity . . . . What?
Is there anything more annoying (painful and frustrating) than busting a knuckle when working on things in the shop? To many of us, blood sacrifices are just part of getting a project done, but it doesn’t have to be that way. This article is NOT about iron gloves or
