So so glad I never had to work on these. All the boom trucks I've worked on have this suspension and if it's bad we send it to a truck suspension shop. Yall have the correct tools and stuff to do it. We didn't.
What does this suspension bring to the table? What makes it better than an old fashioned walking beam and pin suspension? It looks like it has hardly any movement if any at all.
First of, like watching you guys work. Question for you, removing and reinstalling the suspension does that ever cause issues with the alignment of the axles?
Yes. Some suspensions cannot leave the shop without an alignment. It depends on how the alignment is set up on the vehicle. Those little shims I was hammering in are the alignment shims. We usually use the free ones that come in the kit and set it to a neutral position. Then we will gauge the alignment and then just shim to suit. This one was perfect in the neutral position and didn't require adjusting...sometimes we get lucky.
Foden beams were much bigger / wider , made up out of plate, the rubber suspension units were one piece , we called elephants feet , just two on each side .
I have the henrickson HN series suspension. It looks the same as this other than the bolster springs are different. My bolster springs are just two pads on each side, but they're wider and cover the entire surface area of that spot. What im wondering is, is there any difference between these two suspensions? Is the removal and install basically the same or is there so big difference i should be cautious of? Im getting ready to get into mine here soon and get everything replaced, so im just trying to mentally prepare myself as much as possible.
Just out of curiosity, why didn't the bolts go in from the front to the back? That way road grime won't get into the threads. Yall are doing great work!
NOoooo! I noticed you guys put the old/worn auxiliary spring back! Aren't you supposed to replace it? They also sell progressive springs so that you get the 100% contact it's supposed to have... Or am I way off here???
Nice job and good tips guys. That centre doesn’t give the check strap bolt a flat surface to bear on, not a great part of the design of that part but is there a reason for tyat?
The strap prevents the rubbers from being torn in half when you jack up the vehicle. And yes, no flat surface to tighten the bolt against. So we just snug it up.
They are quite durable. Usually only have to be repaired once in the lifetime of the truck. Some co.plain that is a rough riding suspension tho. I dont mind working on them.
Its 20 years since I ran trucks....I had a Leyland DAF with this Hendrickson Rubber suspension......It would last about 7 years on a concrete Mixer running at about 25 tons...or 5 years on Tipper...same weight........so easy to change the rubber parts...never had to do those bushes....they were all OK......even after 7 years......(note: Imperial Tons not your euro tons.)
Interesting channel , could you show what application or types of trucks these different suspensions are mounted on and what the pluses or negatives are to the designs. Perhaps what the estimated life these have types have in general mileage / years your experience . Clues that people should be looking for I order to get the truck in the shop before really bad things happen.
the rebound straps are designed for if you jack up the suspension you don't rip your rubbers in half. Crane trucks especially need these straps so that it doesn't damage any of the other suspension components when they put the truck up on the outrigs.
I hated this suspension as a driver. I called it the 22 tons to get an inch and that inch came from the tires bouncing on the road. I needed a kidney belt on the truck that had it. However the truck itself was a puller.
I once did this very same work. Now, these days at my age I am challenged to lift the one-inch punch you use for alignment. Don't get old young man.
Nice to see people who take pride in their work.
Just stumbled upon this channel, and props to the guys who work on these big rigs like you. Y'all are badasses

Just started following you guys and I have to you guys make it look easy. That’s a lot of bull work. Awesome job
Thanks 👍
You make it look easy,well done.
That’s amazing work!! I do enjoy your videos
the one inch punch named brandon made me giggle alittle
Yes! I've been waiting almost a year for this comment. Thanks. Lol
@@simcoespring Coming from a Canadian, that's awesome 👍. Do you have a punch named Justin?
@@fyrman9092 That would be a pin head...found in a sewing kit:)
Those suspension's take a beating but they are rough riding.
Nice to see how some people do it different depending on the shop, it be nice if my shop had a pit for walking beams and haulmaxx
It’s not bad on the floor
I like your line up punches
Some heavy duty mechanics there. Thinking this stuff is mighty expensive. You gotta be making an awesome living or should be. 👍👍

That is among the most unique/unusual/weird suspension I have ever seen.
It's not the norm, but still far from unusual on class 6 and above trucks with tandem driven axles.

I have seen some trucks have the walking beam bushing on a 30 degree angle plus shims
This rig doesn’t look to bad On the under side especially for the rust belt
Yah, the truck was in pretty decent shape other than just the usual wear and tear of a 14 year old truck.
Hahahah Brandon the 1 inch punch 😂
we have two, Bruce and Brandon, two different lengths.
Foden beams were much bigger / wider , made up out of plate, the rubber suspension units were one piece , we called elephants feet , just two on each side .
I did a suspension system like that a couple weeks ago where I work

What's the maximum gap allowed between the auxiliary spring and the top shim ?

Impressive!
Is that more easy than leaf springs? Is it better suspension? Never saw that before

So all the weight and energy etc is really on those bolts???
My truck is very similar but there is a cross shaft between the two sides under the rubber blocks. Any ideas??
Sounds like an old school Hendrickson Rubber Ride. I've done quite a few of them back in the day.
Topsy from Edison Motors should use that suspension
May I ask why your guys wearing swimming cap ？
Welding beanies. They keep the greese, dirt, and sparks off our heads and out of our hair.
@@simcoespring thank u u guys doing very good job keep unload please
I always wanted to be a Grease monkey but wasn't smart enough so became a builder instead and it's hard work sometimes.
Very cool

I could do some diagnostic videos
@@simcoespring Yes I think that would be helpful to both the truck owners and those only interested in them.
@@heartland96a I see this exact suspension on almost every single boom truck I work on.
A lick of paint would’ve been nice 👍
if you get the bushings that rotate the install is super easy
We used to use those till they kept failing.
@@simcoespring What brand were they?
My strap on suspension is broken can this cause truck to tip over whole dump box is in the air ?

Awesome shit homie
Is the entire weight borne on rubber?
yes, primary rubber then auxiliary rubber suspension.
Looks like the line up punch is made from an old torsion bar
absolutely, best bar ever. my dad made them back in 1986 from dodge caravan front torsion bars. still works great today 40 years later.
Bruce Lee was famous for his 1 inch punch! Should rename your punch..
Bruce is the longer punch, Brandon is the shorter one.
How many hours did it in total?
I think we usually have about 12 hours into these. Sometimes quicker depends on cleaning and welding.

This is the worst hendrickson suspension we have had to deal with in our mountainous location. Rubbers dont last a month
Excellent work . Is it possible to add a translation into Arabic
أضفت ترجمات. أتمنى أن يساعد ذلك.
@@simcoespring Thank you . I appreciate your effort
Rifados
Not the same set up as on a GoldWing.
But should be durable enough.👻
Looks a horrible trade to be in, and im in it, 😄 dont see this set up in Britain.... ..
I talked to a mechanic in Brazil and they don't have these either. They are pretty popular here in Ontario
@@simcoespring saf axles, bpw ,,meritor stuff here , 👍
Send that rusty shit out to be sandblasted and primerd and painted ....damit
This suspension sucks the alignment never aligns even with laser
Why is the one inch punch named Brandon? Wish you would say here goes Brandon!
Brandon Lee...1" punch.
