Volvo A40EFS

[nixs]

As no one have written in this thread yet i start with a little information about the Volvo Articulated Hauler with FS = Full Suspension. I there in Eskilstuna at Volvos demonstration field at their event called "Volvodagarna", Volvodays in English. They have built a A40E with gas-hydraulic individual suspension on every wheel. The had one unit to demonstrate this in a course with plenty of bumps and they ran at full speed and fully loaded with gravel and yet it just "floated" over the bumps! Very impressive to watch! Sorry but i don´t have any pictures to share with.

Hello. Pics of this truck would have been fantastic.

I am not a fan of the suspension system found on the new EFS machine. I bet its more comfy and fast over the bumpy stuff but at what price?
I am glad they have stuck with the Rear beam and elephant foot set up of old. (which has been copied by CAT)

Older CAT 350s have hydraulic-counter acting cylinders on there rear bogies and they tend to break on long bumpy haul roads. (single Units on the front. Accumulated)

I also think Volvo should revert back to Grease filled Osculating hitches like the C machines.
I am not sure if the E machines come with the D series Oil filled hitch? Anybody?

Also. I think ALL A35s should come with sealed brake packs on all 6 hubs. Just like the A40D Truck.

They say that it´s not an A40E with suspension. They say that it´s a complete new machine.
I don´t know if it´s true but I´m pretty sure they have "recycled" some parts.

Oh, there´s an A35E FS as well. The smaller ones don´t exist with FS. Not yet.

I think this suspension system is pretty well approved! Was it not like that when Volvo introduced the arm suspension in the 80ths?

Well, only time will tell. Maybe a mistake like the oil filled hitch

At least as long it is working it is pretty incredible to look at!

Here are two links with some pictures and videos!

Nixs: Does the new A40E and A35E machines use the oil filled hitch?

I don´t know, since i don´t know what a oil filled hitch is. I´m just intressted in excavators!

I think Ross mean if the chock absorbers (stötdämpare) is filled with oil and can lift and sink the dumptruck IE. is adjustable.

Is that right Ross

The Osculating hitch. The Part that connects the Tractor end to the trailer end. Drive shaft runs through the middle of it.

This Part arrowed in the Pic
