Giant truck dumping ramp. Captioned as dumping sawdust. Is this because sawdust can spontaneously explode? Or is this how some trucks just dump?

I have a picture somewhere of my truck on a lift like that unloading grain.
Really cool to watch your truck going up like that.

Several rice mills in Louisiana have truck/trailer dumps like this. I first saw one when I was in highschool. I'm 64 now.

The paper mill at Morrilton, AR had one of those about 1972. Trucks would bring in chips for pulp production, would unload in about 5 minutes. Much faster than unloading logs that were then chipped at the mill.

I bet the view from the cab of the truck would feel something like a Nasa rocket launch if the driver stayed on board through the full cycle.

My only question would be how – what are they using – to secure the trucks to the lifts? I can't imagine setting the brakes would do it. Neither can I imagine operators of these lifts, counting on the brakes holding, if they did.

the driver backs all the way to the chute which is tall enough for the corners of the trailer to be caught in it to insure straight alignment while backing there are low rails on both sides of the ramp of about 6 inches high.(see post #6) yes they set the brakes but those are of little to no use at the slope angle the ramp will reach. There is 1 more securement a pair of hooks on chains that secure the front of the tractor but they are kind of like the safety chains on a bumper pull trailer just much heavier duty and are there for the just incase

Where I worked the lifts never had any hooks and these were rather new lifts, only the wait of the truck and tailor. Notice they are not going up to an unsafe angle! We never had any fall off the lift! I'll tell you thing spooky that happened once, a hydraulic cylinder did fail at the top and caused quite a problem! This is why nobody rides in the cab, not even a dog during dumping, the chip company fires them and the company receiving the chips bans the driver from coming on the plant site!

Jon, The trailer looks like maybe an open top 40' container, possibly even on a skel chassis. No lifting capability. The sawdust/grain fires are because of static electricity caused from rapid movement of particles or high friction, not something that would happen (probably) in an open air dumping....and the volume difference per truck movement would be in the order of 6x based on 14 cu yd truck...just my 2 cents, cheers

They use them for oranges too
