We often joke about safety — Yup, Safety 3rd. While it’s fun to joke, there are a few things we do get quite serious about. How to attach trailer safety chains is one. Today we’re looking at connecting chains on the trailer tongue, so the chain is the right length.

Selecting A Crane Winch For Lifting
There are dozens of ways to lift with a crane. Chain falls are popular. Come-alongs are another common method. There are also a variety of winches – from the hand crank to an electric crane winch for lifting. Is one better than another?
Independent Trailer Suspension – Are You Being Taken For A Ride?
I see a lot of comments on websites and hear references once in a while about the wonders of independent trailer suspension. What do you think? Does it deliver on the hype? Or is it a sales hoax? We will look at some video
The Concept of “Strong Enough”
I’m not sure how to categorize this Article. It’s an answer, but more than that. We get questions once in a while something like “My trailer is X long and I want to haul a Y. Is 3 inch angle iron strong enough?”
Can I Use An Axle-Less Suspension
Axle-Less trailers. Yes, that’s a thing, and we get a lot of questions about this unique suspension. Some people ask if it’s any good? Other’s ask if it will work with our trailer plans? Still others ask about using them for tandems? We even get questions about using it
I-Beam Shape Choices: I, S, W, M or H?
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
Who Says Welding Doesn’t Affect Strength?
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.
Engineering: Calculate Beam Loading (Intro)
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
Low Profile Trailer Suspension
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
Engineering: Welding Trailer Spring Brackets
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
Tricks To Weigh Heavy Things
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 huge or super heavy duty scale? Answer: With some physics and a little math.
Calculating Axle Position
There is always more to the story. Our previous post titled “Where Does The Axle Go?” has spawned a lot of great questions. Here is one particular question asking for some very relevant info about calculating axle position.
How To Make A Trailer Longer
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
What Is The Right Trailer Tongue Length?
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.
Practical Safety With A Crane
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.
Tips To Strengthen A Trailer Frame
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 Build: Where Does The Axle Go?
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,
The Low-Down On Twisting Safety Chains
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?
Trailer 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 the chains more effective?“
Comparison: Steel or Aluminum – Part 2
In the debate about Steel or Aluminum for beams of trailer frames and gantry cranes, there is one big piece we hear less about. An important part of the equation, for sure, is the property of Elasticity . . . . What?
