DUMP TRAILERs Scissor vs Straight Cylinder

   / DUMP TRAILERs Scissor vs Straight Cylinder #11  
I just returned this evening from buying a used (four years old) 6'5' x12' 10,000 dump trailer. It is a single cylinder design that tilts to 65 degrees. the manufacturer, Carmate, says that the dump will lift 10,000lbs which is 3000 more than the rated load capacity of the trailer when you subtract the weight of the trailer itself from the GVW. Another cool thing about this trailer is that it has ramps that store underneath and is low enough to load equipment on, like my tractor! I paid $3200 and a new one in my area is $5600 and change. They have a web site which you can see the trailer on but if I go there to find the address right now I will lose this letter! Mark

Where did you find a used one? I have been looking for several months and see almost nothing for sale except new.

I have no experience with the scissor lift; in fact, I had no experience at all until I bought my trailer. I got incredibly lucky and found one on EBay less than 1 hour from my property with a Buy It Now price of $1,800. Since I had been looking for some time, I didn't hesitate - I had it bought, paid for and back home long before the auction was due to end.

It's a 6' x 12' U-Dump with 12,000# gross. I've had it to the landfill a couple of times, so I weighed it on their scale, and the empty trailer comes to about #2,600#. It has a single cylinder lift to about 45 degrees. The hinges are about 2' forward from the back of the trailer. It dumps lighter loads effortlessly; I haven't had it full of dirt, yet. I've been doing some remodeling and have been hauling wood, drywall, etc., to the landfill. Once I have it tilted up, I climb in the truck and drive forward rapidly, and it all emptys out. It goes up so easily that I'm sure it will handle a full load of heavy material. Legally, I won't be able to fill it full of dirt -- it measures out to hold about 5 cubic yards struck, but that much dirt will weight about 12,500#, so it looks like the most I can carry and stay close to the weight rating is 4 cubic yards. It is gravity down with a flow control, which is nice, especially since I have no cold weather to slow it down.

Why so cheap? It isn't perfect. It has a single swinging rear door, and the hinges are slightly bent - it fits well when closed, but lowers to a drooping position when swung open and hooked to the side of the trailer. It also has some rust -- one side of the bottom has rusted away. I needed to use it right away and didn't have my welder set up, so I bolted 3 - 6' x 4' pieces of 3/4 plywood in the bottom for a temporary fix. Two of the tires are marginal. I spent $18 for two new sealed bulb inserts in the Wesbar sealed marine taillights, and $10 for a new wiring harness. I also spent $20 at Wally World for a little automatic trickle charger that mounts to the side of the battery box, and I plug it into an extension cord every once in a while. I do have a charge circuit wired up to my truck, but I don't tow it long enough to recharge the battery.

Still, at the price I paid, I'm ahead of the game. The electo-hydraulics are fine, the battery is good, the 4 wheel brakes are good, the frame is straight, the dump hinges are fine, and once I weld in a new bottom, put a coat of paint on it and install a couple of new tires, it should be worth $3,000 or more. I'm very pleased. Of course, beggars can't be choosers, and I'd have accepted worse at the price.

Found a used one in a rag called "the want advetiser" a weekly covering all New England. It appeared on a Tuesday, I bought it Wednesday and someone else had called him three times. The good stuff goes fast. Mark

Do you have a trickle charger or a several amp battery charger for the charger you described that runs off your truck power?

The truck-based "charger" I mentioned is just a connection from the truck's alternator charging circuit to the battery. It runs through a relay that is triggered by the ignition switch, so the truck is only supplying power to the trailer's battery when the truck is running. It runs through a standard 7-pin trailer wiring connector which has one pin for auxilliary power, and is the same type of connection used by those pulling camping trailers to recharge the trailer's battery.

I did some research on RV sites before wiring it up; most of them say it is only effective over several hours of pulling the trailer, and it only recharges their camper's battery to about 80% or so. The truck will likely never be hooked to the trailer that long; I just did it because I could. I have the same set up on my motor home, which is sometimes used to pull a race car trailer which has an auxilliary battery. I depend on the little automatic trickle charger running on an extension cord when the dump trailer is parked.

Have to agree with jsimon just added a new cylinder to a dump flat bed on a f450. When over loaded that breakover point pushing straight back bent two cross members that I attached the cylinder to. Just went and bought a scissor on CL for $100. Back to welding and looking for matching cylinder .

Public schools? 2012-2003 = 9 :p (actually a little less since it was Dec '03 vs. Sep '12 :thumbsup:

But, nonetheless, quite a good job of using the search function for ethicsg

I have seen them with two lift cylinders also.... but I would stay away from those.

What are you guys seeing for pricing of these trailers? I am in the market for a 10-12K unit myself to haul firewood. I see prices in Florida much cheaper (20-30%) than here in the northeast. I keep an eye out on Ebay, but that is really a sellers marketplace.... unless you are very lucky.

Why do you recommend staying away from dump trailers with two cylinders?
