Pipeline truck load chart

[m16ty]

I've searched and looked in the TMs but I've yet to find a load chart when using the gin poles on the pipeline truck.

I've thought about adding a winch to the front of my deuce cargo bed to hoist stuff into the bed. I'm thinking I may also add some gin pole mounts to the back of the bed if I add the winch. I'm just wondering how much I could actually pick up with the gin poles. If I can pick 5,000lbs or more would be great. If I can't pick that much I'm not sure it would be worthwhile because I can already pick up 3k with my backhoe.

I've got cranes and forklifts to lift over 100,000lbs at my business but I'm looking for something a little more mobile to use on the farm.

Chapter 5 in FM 5-125 Rigging techniques Discusses the use of gin poles.

Edit: sorry, that doesn't talk about using the a-frame gin pole kit. Still good reading.

Ty, I have some info on that. Keep reminding me if I forget. In testing they quit at 10,000# . The bed does have stifflegs though.

TM 9-2320-209-10-1 page 318 indicates that the winch max pull is 20,000. While I believe that this is the max for the winch, I would also say that the gin poles would not tolerate that much force and the rating is for a straight pull without the gin poles being involved.

This is what I could find.

I'm not sure what the rating difference is but I know there is a difference between pulling and lifting weight!

watch using the front A-frame, real easy to get to much WEIGHT on the front end--tires, springs, frame, and axle housing

From what I have observed you use a 5 to one safety factor when dealing with overhead loads. A 20,000 winch would be safe holding a 4000# load. One issue that would need to be qualified is the question of a safe brake or load lock so the cable does not unexpectedly start spooling out without warning.

10K would be great.
Wouldn't be too hard to add stiff legs. Only down side would be you couldn't move under load with the stiff legs.

I'm taking about mounting the A-frame (gin poles) on the back, not the front.

I know the rating for front A-frame- 1,500 lbs. I think it's listed in the -10.

The 5:1 ratio would be easy to overcome. Just add parts in the line.

I'm also not sure winches have the 5:1 safety rating. I know on our cranes the winch just stalls (hyd) when we get to winch rated load. That would lead me to believe the winch is maxed out at that load. If the winch stalls we add more parts to the line. I could be wrong on this. I do know the winch line (cable) does fall under the 5:1 rule.

The deuce (and 5-ton) winch brakes aren't ideal for overhead lifting. I do believe they are capable though if kept in adjustment. Converting the winch to hyd will also help holding a load as hyd motors don't like to spool when the oil isn't flowing.

The way the winch gears are designed they will not unwind/backspin unless the load is excessive or it the winch is worn. I've spoken to engineers at winch manufacturers and THAT is the word. Overhead lifting is on a completely different safety and rating scale than a straight line ground pull. Again, I don't know the reduction but I wouldn't think 5:1 is out of the question. I do know I had roughly 8,000lbs suspended from the 20,000lb Garwood on the front of my modified deuce crane truck and it held it fine WITH THE BRAKE REMOVED. The winch brake is not a load holding device, the engineering in the winch IS. I've had over 2,500lbs on my 10,000lb Garwood many times and it was fine with that...WITH THE BRAKE REMOVED.

disclaimer: Your truck = your winch. Don't do what I do because obviously I don't know what I'm talking about with winches, loads, the dumb brakes, etc.

The 20K rating I mentioned is in the TM in description of the winch on the pipeline truck on the back.

The 5 to one rating I mentioned was for the line, and not for the rest of the rig. I am sure there is a very solid limit on the rear suspension of the truck. Remember the M62 and M543 and other versions with the rear crane have additional components in the suspension to even out the forces and stabilize the truck. This is in addition to the riggers already on the truck.

I would offer that any endeavor that would entail overhead lifting should be approached with extreme caution and an awareness of the limitations of the equipment involved.

There is no excuse for not practicing good safety procedures.

I agree. I'm just trying to hash all this out. I'm a certified crane operator and have built from scratch booms that lift over 100,000lbs. I guess I'm trying to say that this Gin pole idea isn't my first rodeo.

I haven't done it but I can figure how much it can lift and keep the front wheels on the ground fairly easy. If the rest of the truck can handle such loads are to be determined though. The military is pretty thorough on what you can and can't do with a piece of equipment. I just figured they would have some sort of load chart for the pipeline truck. If spicergear had 8K hanging off the front of his truck I wouldn't think 10K would be too much for the rear.

On the subject of the the winch spooling backwards, I've personally witnessed a 45K wrecker winch (mounted on the back of a civi KW) running backwards through the gearing. On our M870, if you have a heavy load on the trailer and are raising the neck and stop while the neck is being lifted onto the truck the winch will spool backwards.

WLL of 5/8" wire rope (as used on a 20K winch) is around 6,000lbs depending on the type of rope. 1/2" (as used on a deuce winch) has a WLL of about 4,000lbs depending on the type. These figures can be a lot more or a lot less depending on the makeup and grade of the wire rope. For instance, we have a crane that runs 5/8" wire rope and it's good for 9,000lbs single line pull. If I use a deuce winch it looks like I'd need a 3 part line to pick 10K.

If you add stabilizers on the rear of the frame that would virtually eliminate any load being placed on the rear suspension. Now if you wanted to move with the load, the setup would be severely derated for "on rubber" lifting. One problem would be the stock deuce suspension and the other would be a big change in center of gravity.

To clarify just a tad, I had 8,000lbs hanging on the winch...which was 200' away from the load being lifted straight with the 5/8" cable going over a heavy snatch block back to the truck. It was a straight up lift, but there was little weight actually ON the truck. I do feel however, that you could hang 10k off the rear as you surmised WITH stabilizers.
