Which hoist is better scissor of 3 stage cylinder?

I wonder which is the strongest.This is a single axle 10' dump body.Both have single cylinders.It seems the 3 stage lifts higher.What are pros and cons?

Like anything else it's debateable.
I think the 3 stage is better for strength and durability.
The scissor lifts have too many components that can result in failure. If get yourself in a situation where you are un-level and are loaded heavy to the front I have seen them twist and either a pin popping or sub frame twisting. Not saying a 3 stage cylinder won't give out either but with the cylinder at the front of the body as a lifting point compared to the scissor lift somewhere around the center of the body it just seems to be better especially with wet dirt or mud.

Agreed the pickups in our shop have scissor lifts, but our single axles with 11 foot beds all have 3 stages and i would trust them more than scissor lifts. Just my opinion.

I truely belive in stage lifts. Even the frameless dump trailers use the stage lift, and they are the most unstable units on the road when it comes to dumping them. A wind change can tip one over!

Stage units for me too!

I have a sissor lift on my F600 single axle dump truck. It's requires greesing it every day that I use it. Off the top of my head, I think there are ten zirk fittings. You have to have the bed up to greese it, and I use bot a fixed and flexibe tip grease gun to do this.

Twice now, I've had the pin that comes off of the part that attaches to the cylender break off. The first time it happened, I had a local welder weld it back together. The second time, I went to the most expesive, but also the best welding shop in the county. Big price difference, but it's held up for three years now.

If you ever want to hate life, try pulling apart the pieces to a sissor lift and then putting it back together again. Truly one of my all time miserable experiences!!!!

Just becasue I never, ever want to do that again, I'd buy the 3 stage lift over a scissor lift. I hate it so much that I'm thinking of selling what I have now, and what's working fine, for another dump truck just because that's the only way I can be 100% sure to not have to do it again!!!

Stage lifts are less maintenace, and in my opinion much stronger. I agree with what everyone else is saying...

I have a 3 stage lift on my 12 year old dump trailer and it has never had any maintenance and still works and looks like new. It puts less stress on the frame lifting from the front IMO

I've had both. I went to the front lift for strength but it's not like I ever had a load that wouldn't raise and dump on the scissor lift.:beatsme Since you are talking about a 10' body the downside to the 3 stage is that the "doghouse" takes up a decent amount of space in the front of the bed. If you ever carry pallets or a tank in the back like I do sometimes, it is a concern. Also the doghouse give you more corners for sticky material to hang up in. I had to shovel less with the wide open scissor body.
Everything in life is a trade-off...

I drove a truck once that had the 3 stage hoist mounted outside the box on the front with an A frame on hinges at the bottom of the front wall of the box so there was no doghouse in the box. It made it a lot easier to clean out the stuck asphalt than the truck I usually drove that did have the dog house... I'll see if I can't locate a picture of it... I'd stay away from the scizzor lift, I recently came across a truck with a bent frame where the scizzor lift was mounted... I put pictures of that in a thread called "Slightly Bent Hino", I have no idea how to link it to this post though...

Thats the way my trailer is set up

Have a full load ,with a blown hyd. hose, or just low on fluid with a scissor lift - that should make up your mind after having to empty to raise to work on .
Also the scissor lift get so rusty they come apart before lifting ( when old and junk)

I used to drive an Autocar for a road building company that yada dual cylinder scissors lift on it. Whenever there was site work to be done that was the truck they would send. It was the owners belief the truck was more stable than a front cylinder style truck when in unlevel spots. I dumped that truck in some pretty precarious positions and it always held its footing. Later on that job I drove a Mack with a teloscopic hoist and it sure did seem there was a lot more sway to it. I wouldn't put that truck in the same spots as the autocar .

I will agree a scissors hoist is much more complicated. I've seen some that have rollers that slide up a rail to raise the body, and I've seen where one of these rollers can jam and the wear a flat spot on the roller and a groove on the rail requiring extensive repairs. I also feel a front cylinder truck can lift a heavier load than a scissors lift.

I recall the pictures of the Gino bent in the middle and in that case I'd bet the hoist used was not the proper one for that wheelbase truck. All the ones I've seen have the sub frame the full length of the body it is under.

Why do you need a scissor hoist? Why not a triple piston underbody hoist JJ & Bristol Donald make them ,thats what I have .they replaced the scissor hoist!

To be honest, after reading this thread, I was quite surprised that the scissor type hoist is still being used in the US. There were several variations of that system used DownUnder for many years, more so on smaller trucks (up to 8-10 tonnes), but you just do not see them today. Telescopic hoists have been used now for years and for me, I would not use anything else. They lift where all the weight is and I feel, are much more stable than any under body hoist. I base that on many years of tipping and spreading, using both systems.

This G-well hoist and others like it were used on just about all early tip trucks and I am not sure, but they may have used them, because no one had designed a telescopic ram, but don't quote me on that. This system is similar but, a little bit different to some of the scissor lifts I have seen on HEF.

A telescopic cylinder will lift a lot more at lower pressure than a scissor.But if you have a catastrophic failure in a telescopic thing can get bad.I recently purchased a 2003 mack granite tandem from an insurance company.The driver was dumping backed up a steep stock pile. When the body was part way up the weld gave way at the base of the cylinder sending the loaded body crashing back down and putting the top of the cylinder through the rear window.If the driver had been looking out the window it would have been much worse.As it was he bounced off the roof and was knocked cold(no seat belt).The truck was really over loaded a scissor probably wouldn't even have started up.

Need some help with a scissor hoist, I bought a new Hino 18,000 GVW and had a custom body built that I've been unhappy with since I took delivery. The body is perfect, the hoist/mounting arrangement is the problem. I have had a few bodies built by this company (never a scissor) and they are always top notch, they purchase hoists from an outside source. The dump angle is about 53 deg. When the bed is fully raised, the majority of the weight is obviously on the rear hinge, the scissor hoist bangs any time the truck is moved with the bed fully raised. When the bed is partialy raised no problems. The body builder replaced the scissor unit once already, 1 3/4" pins through a 2" cylinder hole. I just got the truck back and the pins seem to be tighter. The body builder put wedges on the hitch plate under the rear hinge that barely come into contact when the body is fully raised. I was told that it would keep the hoist from over extending? But the body still has play(up and down) when fully raised. Not sure if the dump angle is too much, I have never had this problem on any other scissor hoist though??? The truck has only 4000 miles on it so trying straighten this out before it keeps taking a beating. Any ideas on reducing the dump angle or putting a small telescopic under body hoist on it. Any help is much appreciated, Thanks Steve
