The Hills Bulk Waste Pt 2

Really gets full in this video...

[@corsiboy]

This was an incredible couple of videos. this is probably the best couple of garbage/rubbish trucks on youtube imho

[@bitterman112]

Man!!! That truck was packed out!!! I noticed that when he tried to pack that large metal object at 6:50, the packer blade didn't curl fully to the sweep position!! I hope the truck went to the dump after that stop cause I would be afraid to see that tailgate burst open lol!!! Great Post!!!

[@AussieGarbo]

KabakaLion knows exactly what he's talking about. Each body, depending on the make, has it's own individual pressure set for cut-out. When the pressure is reached, the hydraulics cut off like mentioned above. In this video the blade stops closing because it just can't pack any further (you can hear the revs struggle), but an example of the cut-out is when the revs stop droning and the blade starts raising...

[@AussieGarbo]

They just got all of it on, and I was very surprised they did! He told me their next collection was in a different suburb, so would've been a pain coming back for this one when they were in the area - makes sense why they did what they did :) When I've been on some routes, the drivers can really fill the trucks up, sometimes when you can't get anything else under the blade.

[@AussieGarbo]

On older models you'll find these cut-out systems weren't around, but on the newer models you're bound to find it incorporated into the system. I'm pretty sure the main use for them is to take pressure off the cylinders/rams, hoses and the pump to avoid damage to the truck. I know on some side loaders down here where once the system pressure is reached, the pump or packer will shut off automatically so you won't be able to load any further, resulting in an inevitable trip to the dump.

[@FormerWMDriver]

There's not much space left in there! Great catch! I know what it's like to be in that position... all you want to do is get that last little bit on. I hope they didn't have anything else that they needed to jam in there.

[@AussieGarbo]

I'm not totally sure what the force/psi. is set at for this truck, but it would have to be atleast 1500 I'd imagine for it's application and size. To answer the second part of your question, pushing the packers like this may make the lines blow. It has happened before on the trucks in my council where you're really forcing the packer, and then you see the hyd. oil leaking. If there's enough force, a hose can get blown and sometimes the pump itself under too much pressure.

[@mikeyfromnj]

Nice vid, Mitchell !!! Thanks for putting that up. I like the bulk vids the best. Shows you the shear power of hose blades!! Speaking of which, how much force do you figure the blade on this truck has?? And is there the possibility of blowing the lines if you push it to much???

[@AussieGarbo]

All from one house - suprised they took everything that was put out!!! Also can't believe it all got packed in!

[@mikeyfromnj]

Thanks for explaining that, but how much force is exerted to the trash, 10 tons, 20 tons???

[@AussieGarbo]

Yer I love seeing rear loaders struggling like this, very entertaining :) I reckon the packer had just given up after all that, couldn't be stuffed packing anymore lol You can bet they went to the dump after that, I bet the tailgate wasn't far from jumping off the locks with all that pressure. Thanks for the comment!

[@mikeyfromnj]

Sort of like a circuit breaker would act, right?? Would you know how much force??

[@arkansastrash320]

I like seeing a rear loader get over powered.not that it couldn't crush stuff it mashed the pudding out of that washer or wahtever it was but it could not do a full sweep or full pack cycle cool.Funny it lost most of its power in the seep and hold the sweep part but the raise up after it sweeps did not up or down it was still visious.I guess everthing has its limits and it sure did excelent show..

[@GarbageTrucksAZ]

Great job!

[@Powerpresse]

Great work! Thanks (also for the first Video)

[@independs]

that is one full truck!!

[@internationalRLfan]

did u give them a reward?

[@FormerWMDriver]

Oh yeah, I definitely would have done the same thing even if it took an extra 10-15 mins... especially if it saves them the drive after dumping out.

[@AussieGarbo]

Probably cleared the hopper first, take the weight out of the tailgate... but who knows, could've been totally the other way around.

[@AussieGarbo]

@FUGlitchyLogin Yeh they got the pile on luckily. They had to come back for more material, but this was in an area closer to the tip.

[@r6man2]

Nice good job!

[@boblamb8421]

Overpacking is a mechanic's nightmare. It does damage to just about every part. Causes the body to bulge. Every time he holds that lever forcing the pump to by pass he is overheating the system especially the pump. Causing the oil to get really really hot. You would not be able to touch the hydraulic tank. This not only ruins the hydraulic oil but does damage to everything from hoses to cylinder packing to the pump thrust plates. I am surprised that guy with the hat leans his face in the hopper like that. The hoses on the packer curl cylinder's stalled like that can reach 3500 spike PSI. If any one was ever seen a one inch hydraulic hose break at that pressure better hope your face is not in the way.

[@AussieGarbo]

I appreciate everything you've said in this comment, it's good to see some feedback from a mechanic's perspective. Thing I've learnt in this job is that a lot of guys that operate this equipment in this fashion have no idea about the wear and tear it causes or how intense the hydraulic pressure and strain on components is. I guess the guys that do know just don't give a shit. I'll admit I've had my moments in the past where I have tested out the packing capability of certain trucks, but over the years I've come to realise a lot and become pretty "sympathetic" towards this equipment doing this nature of work. I've always hated when operators run the pack valves manually via levers and continue to hold them open even when the cylinders have achieved their maximum stroke for that cycle, with the pack blades at a creeping standstill and the engine/pump evidently under heavy load. I've always had that idea where once a cylinder has visibly reached its end and you can hear the engine sound change when it's loading up from resistance at the pump, you relieve it of pressure flow and allow that component and section of the circuit to settle. I sometimes even run the opposite function a touch to release the pressure and tension that had just been built up, so the pack blade and hydraulic lines are in a more "relaxed" state. So many little things that can be done to make a big difference and prolong the life of the machinery, but many are oblivious or ignorant when it comes to running hydraulic equipment with care and respect =[

Revenge of the box spring!

[@espeon_196]

packer blade test......

[@AussieGarbo]

Changed to on-call.

[@AussieGarbo]

Sorry but I can't answer that, wouldn't have a clue.

[@AussieGarbo]

haha Nah, missed me...
