Hello I'm wonrdering about a few things from the Roll off systems that are used on roll off trucks in the USA. 1. Does the driver have to leave his cabin to connect and disconnect? 2. Is it a 1 or 2 cable system? 3. What is the width between the 2 girders under the bottom? Is this the same like the width from the truckchassis? 4. As far as I can see the cable is pulled by extending a Hydraulic cilinder inside the roll off system. Is this correct? Thanks in forward

I have some hydraulic roll off trucks and to answer your questions
1. Does the driver have to leave his cabin to connect and disconnect? No but he does to undo the tarper and it is hydraulic as well
2. Is it a 1 or 2 cable system? 1 cable
3. What is the width between the 2 girders under the bottom? Is this the same like the width from the truckchassis?
Im going to say about 3 feet
4. As far as I can see the cable is pulled by extending a Hydraulic cilinder inside the roll off system. Is this correct? I think the cable has a drum that pulls it like a winch on a dozer

Thanks Bret Browsing the internet I noticed that those systems are different from what we're used to here and so they caught my interest

On the ones I've run yes you must get out of the truck to attach or detach the cable from the container, it is a one cable system and operated by a hydraulic cylinder that lets the cable out as it extends or pulls the cable in as it retracts. It is located between the roll off frame rails, the ones the hoists raise and lower. The width seems to be fairly close to width of the trucks frame.

Ok thanks CGK3 So it's more or less like a horizontally placed boom of a forklift?

Great topic! I'm currently trying to get a job with a roll off company in my area since ive recently got my CDL and was curious about a few things.

I guess it all depends on where in america you're talking.
Over here in the pacific northwest most of the roll off trucks are chain-drive and the driver doesn't have to leave the cab other than opening the doors and disconnecting the trailer. however we just switched over to a Palfinger hook-lift system, I'm pretty impressed so far, it gets a much greater dump angle and is more stable while loading and unloading boxes.

Here in NJ, The system that I like the best is th Hook-lift such as Eric has mentioned. Much more stable, more powerful and just a better operating system all together. The company that we contract with has 5 of these trucks and what these things can pick up is amaizing. Just blows the old system away.

Back when I worked for WM (Waste Management) and BFI, I drove a Mack roll-off, hauling 30 and 40 yard cans. Yes, as a driver you do have to leave the cab to hook up the can (the single cable ends in a metal elongated loop that is engaged with a hook on the can), after raising the tilt frame. The cable, as has been described by others, is pulled in by a hydraulic cylinder within the tilt frame, whose width is more or less equal to the truck frame's width. Before placing the can on the truck, we had to manually tarp the can (new roll-off trucks now have the automatic tarp, saving the driver from having to climb up, and many times into the can to tarp). The operation of getting the can on the truck was one of winching the can up the inclined tilt frame, while gradually lowering the frame until the can was on and the frame lowered for transport.
We hauled not only open top cans, but also packers (a container that fits onto a stationary packing machine attached to a building), and self-contained packers (a can that has a built-in packer that compresses the trash inside). The self-contained packers had to be loaded with the packer end to the rear for weight balance, when I got to the fill, the can had to be set off, and turned around so the door would be at the rear to dump the load.

Seems to be a fastidious job !!!

I have seen both the cable and the hook setups around here.

Theres mostly Cable roll Offs around my way.the 2 i beams in the dumpster,are a little bit smaller thans the trucks frame width.My Job over the summer was finishing plumbing fixtures the inside of houses under cosntruction over the summer,and based on what i seen,it looks like the driver does have to get out and the hook the cable on,also he has to climb up on the side of the dumpster and make sure theres no loose cardboard or other materials that may fly off the truck even if the tarp is on,that you just move that crap into the middle of the dmpster.they also think and actually bring a dumpster on the truck,pick up the old one,then drop the new one off,so there is no down time. Just a question but isent the hook roll-off system is also called an ampliroll?

Interesting reply's The chain system that you see in the US? Are they called Translift? In that case they're Dutch Here we don't see the One cable + cilinder system. basically you see 4 types. 1. Double cable frame. The 2 cable 'eyes' are connected to the girders from the box. The driver has to leave his cab to connect them. 2. Chainlift. The driver positiones the truck correctly in front of the box so that the guide wheels on the backside of the system are on the outsides from the vertical girders. Than he lowers the tail from the chain and after this he lifts it and the chain picks up the box. 3. Hooklift. I think that the German company Marrel was the inventor of this system and they indeed called it Ampliroll. This system has a few defects compared to the others. A longer chassis also includes that the box has been lifted (unnescesary)higher while loading. Also there's a risk that the box ends up outside of the two guidewheels, because the box is not from the beginning between the guidewheels. 4. belt system. basically it works like the chainlift, but it's lighter weighted I will add a link to the website from the producer later. Here it is http://www.transport-systems.nl/bandsystemen.html

R954BV wrote:I wouldn't make a protest against a picture from this truck loading a full box Well I just looked through my pictures, and couldnt find any more. I may have some on another computer, which is an upcoming project. But I did steal some from Eric P, ill show those to give you an idea. Now as you see, he was stirring the pot in a previous post. There were times I had to help get these 90 yarders on the trailer. It seemed to be a problem with the Kenworth, more so than the Frieghtliner that was pulling the trailer most of the time. The hydraulic system on the trailer was set so that it would not pick up a box that would be over weight for the truck/trailer combo. It was rare that they were overloaded. It all depended on the material I had to load in the boxes. When I loaded aluminum I was never over weight. I had a few loads of Shread that were overweight. Then I was always overweight on the boxes full of silicon steel sheet. If the truck could not pick the boxes up and we thought we were close on weight, I would sit next to the truck and trailer with my 320. Grab a hold of the front of the box and lift up and pull at the same time as the driver would with the cable. Once it was started, I would run to the back and help push the can on the trailer. Sometimes the lady in the office would holler at me saying it was over weight, or under weight but usually i was pretty close. With the extra axles on the trailer, it was rare for the truck to lift off the ground. It is a lot better balanced than the tri axle roll off trucks you see around.   Yoder, you must not have seen the day they came in with a 20 yarder on the truck that I had to unload before they could dump. It came in from the other plant. The power company pulled the cable from the gm plant to the power plant. The drive came in and told me i needed to help empty. Seems it took the guys over at the power plant two forklifts pushing while he pulled. I saw the scale ticket, 174,000 lbs for the whole combo. We know a 20 yarder doesnt weigh much more 2000 lbs, I would say the truck and trailer were some where around 60,000 lbs. So they brought me some where around 112,000lbs of lead jacketed armor cable
