Talk:Dump truck

Manufacturers
I find the terminology for this page a little ambiguous, concerning "dump trucks" vs "dump bodies." Most of the listed manufacturers build power units and chassis', but don't actually produce a finished "dump truck." The business end (lifting cylinder, hydraulics and dump box) is added after the power unit is delivered, often by a 3rd party assembler or integrator. So who qualifies as a "manufacturer" here?

I added Beau-Roc to the list, then realized that none of the their competitors (Godwin, Crysteel, etc) were in the list either. Lyn (talk) 20:02, 26 May 2017 (UTC)
 * Virtually all truck brands have a dump truck chassis, should they all be listed? EDIT: should there be any section at all? Heavy equipment manufacturers do build complete dump trucks. There could/should be a separate body section either way? "Manufactures" could be done separately. Some body manufacturers build both boxes and semi-dump trailers, others build either/or. Should trailers be included? This is an international article, should bodies from different markets be used? Just a few thoughts. Thank you. Sammy D III (talk) 00:38, 27 May 2017 (UTC)

Euclid Dump Truck
Does anyone have information on this truck??


 * The company I work for used to have 10 or so Euclid Trucks, they wear 60 ton trucks, green, and very loud. My understanding is Hitachi bought out or merged with Euclid, and they are still around though it seams there trucks are not particularly popular, why I do not know, we have switched to all cat trucks. http://www.hitachi-c-m.com/global/news/press/PR20050131114648945.html Zath42 16:11, 10 April 2006 (UTC)ok

Error in "Standard dump truck"
Reading the part "standard dump truck" I was confused a bit. Obviously it explains the construction of a semi-trailer dump truck (which has its own section below) and not a solo truck. Besides it might be explained that the hydraulic ram is placed either in the front of the dump body or somewhat under the middle. Also some are configured in what we call 3-way-tip here in Denmark (don't know if there are special english words for that) that can be set to dump to rear or either side according to needs.

The reason why I don't correct it myself is that I'm not that sure of the technical words in english - I only drive it in danish :-) G®iffen 14:05, 24 March 2007 (UTC)

I agree the language is broken. The classic 'dump truck' as understood in the United states would include a single truck such as shown in the first two photos. A semi-truck with a rear dumping trailer certainly exists but isn't the classic of which I think the British call a 'tipper'Rvannatta 06:55, 16 September 2007 (UTC)

Not understood
I removed this from the part about "Side dump truck":Its key disadvantage is its length which impedes maneuverability and limits its versatility. I don't know how those are built in other parts of the world, but they surely have the same length as any other dump body where I come from. Maybe I'm not thinking of the same type of vehicle, so i picture wouldn't hurt anyone.

Also I didn't catch the "super dump truck" part? It's a one-liner and no pic.

The side dumps the company I work fore uses have the same length as most tractor trailers. They are longer than the tandem dump trucks, we use and the same as the belly dumps. Zath42 01:43, 25 March 2007 (UTC)


 * Thinking overnight I thought I'd better clarify myself. I've never seen a belly dump, except as a railroad car. The side dumpers I've seen are actually trucks or full trailers with what I know as a 3-way-tip or 3-way-dumper (I still need that english word for it). By moving one or two bolts under the dump body, the driver sets which way to dump the load (left, back, right). At the pic you can see a system for locking the dump body for side dumping. Hard to explain when I don't know the tech words, but a pin is released from the "open" position, the lock part pushed in, and the pin re-inserted to lock the system. At the same time one must remember to open the diagonally opposite lock. This is why several manufacturers make systems with only 2 lock bolts. Then 1) you have to remove it from the unlock position in order to use it in the lock position and 2) if you forget to re-lock "the other" you will notice that you are standing with some weird bolt in your hand... G®iffen 08:30, 25 March 2007 (UTC)


 * That picture is hard to see what exactly you are talking about. However the side dumps I'm used to do not dump back, there are some pins that lock the trailer to dump on one side or the other.  This web page  has a video showing what I think of when some on says side dump, and is like the equipment my company uses.  In this video the tractor is pulling 2 trailers, we only ever use one trailer per tractor, otherwise the length really would become an impediment. Zath42 06:51, 26 March 2007 (UTC)


 * OK, I've never seen that on a truck. I'm thinking of another type. G®iffen 15:47, 26 March 2007 (UTC)

Superdumps
I added a line about Superdumps being developed by Strong Industries. This is a factual statement rather than a promotional one. While other companies produce trailing axles (in limited production), the Superdump concept is unique to Strong Industries. —Preceding unsigned comment added by Sptruck (talk • contribs) 17:16, 21 January 2008 (UTC)


 * Is there a generic term for the concept of which Superdump is a brand name? (Of course, if Superdump holds a patent, there might not be one.)--Maxrandom777 (talk) 15:04, 30 April 2008 (UTC)

Need one good photo in profile showing a load being dumped.
The article has enough pictures of different kinds of dump trucks, but what it really needs to make the idea totally clear is just one good profile (side-view) photo showing a dump truck with the bed tilted most of the way up and the load visibly pouring out. — Preceding unsigned comment added by 107.8.75.252 (talk) 10:51, 22 May 2012 (UTC)

Name in the UK?
I'm from north-east England, and have also lived in north Wales and Merseyside, and I have never in my life heard the term 'tipper.' It's dumper truck in every context, as far as I've ever known. Maybe tipper is used elsewhere in the country, but imo that sentence needs rewording, specifically the word 'only.' I'm not 100% sure of a better way to put it at present, though. — Preceding unsigned comment added by 94.192.255.252 (talk) 14:41, 24 June 2012 (UTC)

 * I'm also a northern type by both birth and inclination and as a small Mr Larrington remember the terms "dumper" and "tipper" being used interchangeably. Mr Larrington (talk) 12:48, 5 October 2014 (UTC)

A dump truck is not a "dumper" in Scandinavian languages
The language list in the article linked to the Swedish, Danish and Norwegian article "dumper". This is wrong because "dumper" in Scandinavia means articulated hauler. I changed it so it now links to "Lastebil" (Norwegian) and "Lastbil" (Danish & Swedish). The best Norwegian word for dump truck is "Tippbil", but it has no article yet and since "tippbil" is a particular type of "lastebil" I used the latter one.

20/05/2013 reword
Shorter boxes often use under bed hoists, which do not have a "doghouse" which intrudes into front of box.

Here 6x4 tailgates commonly can also hinge down on the lower gate lock, allowing protruding loads to be hauled.

Do ANY EU trucks have tandems with both axles powered?

Comet is 4x2, not 2x4.

US strait trucks often have a longer wheelbase than a tractor and the tractor tandem to trailer tandem, allowing semis to "jackknife" through tighter turns.

"Tandem dump truck" is accurate, but picture illustrates a pup being dumped.

Bottom dumps cannot dump into a paving machine, and may have trouble with sticky asphalt, anyway. Primarily used for aggregate which will be spread with a "road grader" or "bulldozer"? Not sure, they are not used here.

Tipping over is more common among larger trucks, especially semi-dumps ("bombers" here), which are very tricky.

Dumps (all trucks, actually) are dangerous anywhere, not just in car parks.

Sammy D III (talk) 16:34, 20 May 2013 (UTC)
 * The box of a dump truck, made for hauling construction material, is pretty remote from an auto trunk lid, or a station wagon's rear door, isn't it? Do trunks or rear seats in station wagons dump? Nowhere in the link is there any reference to trucks of any kind. The "tailgate" link leads to an article which also does not refer to trucks, although it probably should. That link also removed. Maybe modify the link's destination before using it?Sammy D III (talk) 17:17, 6 June 2013 (UTC)

this article is a load of rubbish
the amount of crap thats been shovelled into this article without any citations is just un beliveable. i vote that this article be deleted and started again without the help of armchair fan boys who probably have never even driven a ride on mower let alone a truck. — Preceding unsigned comment added by 101.168.213.79 (talk) 03:39, 1 January 2015 (UTC)

Cut and past in different order. Combine and edit duplicate info. Reword, add a little, cut a lot. I think “tri-axle” and “quad” are nicknames, and they don't match the next sentence, so I cut them. Maybe someone can make them fit? I also cut “pusher” and “tag”. Do EU 4 axles have powered steering axles? Pics: right now there is no pic showing the actual unloading, dumping dirt on the ground. Neither cabover Kenworth K100 or Unimog are very typical, the Kenworth is sort of bizarre. All except lead (good shot) and Bedford are US. I want to show US vs EU 4-axles. I'm going to add a couple, lose the KW, and maybe replace a couple with better shots of the same type. Semi-tractor para right behind Standard, single trailer before other combinations.

Are roll-offs and roller containers dump trucks? Sammy D III (talk) 02:01, 23 September 2016 (UTC)
 * They can be, because many are able to lift and tip the contents without unloading the container.Andy Dingley (talk) 09:24, 23 September 2016 (UTC)
 * Thank you. Someone was on it in 2009, then took it down. Sammy D III (talk) 18:43, 23 September 2016 (UTC)

Various
First, I've seen various dump-carts from between 1860 and 1890. They were pretty common. This article makes it sound like it was something that never occured to anyone until the late 1800s. They had two axles, heavy duty, and a cast iron pivot. The pivot is set slightly behind the axle, and half of the box sets over air behind the pivot (no frame under that part). The front half of the box rests on the frames, and is held down by an iron pin, sometimes with a limiting chain. It is loaded with a slightly rear-biased distribution, to ensure proper dumping, but not too much, or the pin will jam. When the team of oxen or horses is backed to the dumping location, the pin is pulled out, and gravity causes the box to tip backwards. Once empty, the box is tipped back down by hand (they are rarely to large), and the pin re-inserted. Similar devices were put onto early trucks, often home-built. We have a Model TT truck with exactly this sort of setup at our old farm in Massachusetts, sitting rusting quietly in a barn somewhere.

Next, the article on "Superdumps" seems to be talking about a typical rigid-frame truck. That's what I think when I see "conventional straight dump truck". But the image shows a semi-tractor pulling a type of dump trailer. That's an important clarification (actually, the same is true for all of them...a dump truck is not exactly the same as a dumping trailer towed by a standard tractor). It also appears from the photo to just be a handy place to mount a pup-trailer, rather than using a dolly like other towed trailers do. I think a picture showing just the extended wheelbase and dump box would give a better idea what the writer is talking about, especially if there was an explanation for laypeople about weight/length limitations, so they can understand why it's illegal to carry 80,000lbs with the dolly raised, and why it's okay with it lowered, and why local length restrictions dictate that the lift axles be x number of feet behind the axle, not in front of it (I assume...unless it's just that they don't fit there).

As for side-dump trailers, as far as I know there is no reason whatsoever that a side-dump must only come in the form of a long, semi-style trailer. In fact, I've seen a number of off-road side dumps, universal dumps, tracked dumps. Long side-dumps may be a popular alternative to long tilting dumps, but they are now by any means "The" side dump. Side dumps are also popular in other countries, I believe. Now, I also don't see why it says "they are almost immune from tipping over", only to follow with the claim "except they may well tip over if unloading is interupted prematurely". That's not what I call "immune from tipping over". Clearly this could be improved. I also don't quite see why a side-dump should get stuck from unloading materials beside the wheels when bottom-dumps are expressly designed to pour the materials right out the bottom, with the rear axles getting dragged right through it during/after unloading. It's the only way to empty a bottom-dump. They seem to do fine.

Also, if they are "only refered to as dump trucks in the US, elesewhere being refered to as 'tipper trucks'", then why does the article go on to talk about "dump trucks" every time it refers to European tipper trucks, or shows a caption illustrating a typical 8x8 European tipper truck. I know it's good to strive for consistancy, but I think in this case we could just use the terms synonmymously and refer to the Euro trucks in the Euro fashion when it's clear that's what's being referred to.

Is the three-axle dump truck any good?
Three axle dump trucks are larger and heavier than two-axle dump trucks. These vehicles are usually more powerful and have more storage capacity. Three axle dump trucks can carry up to 26 tons of materials and have a maximum weight capacity of 45 tons during loading. The 3 axle dump truck is a powerful, fuel-efficient workhorse for any construction site. It has a high payload capacity and low center of gravity compared to traditional dump trucks, which makes it easy to maneuver over uneven terrain. The low vibration and lower fuel consumption make it an ideal vehicle for local hauling or construction work. Three axle dump truck is good. Yato137 (talk) 08:49, 17 August 2022 (UTC)
