Marion 7400 Working With Lima 2400 

Yet another great video Justin. I really like seeing old iron like the Lima dragline at work. I was once told they were the cream of the crop back in the day. They were engineered to last a great deal of time. Turns out they were right. Awesome video !!!!!!

I like the angle you were able to get to watch the 7400 at work. I don't think I've ever seen a dragline working from that close to the far end of the boom.

love the tires on the boom to keep the cables from rubbing

I grew up with an abandoned 2400a in the field near my house in Windber, PA. My dad used to take me up there to play in it. We were always respectful to the beast but other idiots in the area were not. They busted all the windows out, beat the pony motor apart, threw the internals out the doors and windows, ans spray painted all over the poor old fella. That got it negative attention and of course it wasn't long before the scrappers were called. I still have a soft spot for the 2400s.

What skill both operators showed working together lots of experience

The operator can control his dig pattern and he won't be further away from anything. When that high wall is shot, it will land right in the pit he's digging out now. With the help of a dozer, he can level the shot off and make a pad for himself to sit on, advance forward and throw the rest of the rock behind him. To mine with a machine like this down 200ft requires a skilled operator.

Lima 2400 A up on the pile, I have run 3 of each the Lima 2400 Draglines, And one (1) each of the 2400 A&B three drum Clamshells ... Glad you showed it from the 2400’s point of view to at 5:18 on the Clock...

@dragonriversteel Thank you! You heard right, the Lima's are heavy, tough machines that can take on hell of a beating. They are also hard on the operator too. This one's from the 60's

Justin those drag line boys sure know there stuff great operators

If you look you will see the drills ontop of the highwall right before I show the Lima. They will fire another section of the highwall down, the 7400 will build his own bench and advance forward, move the rock and take out the coal

Alwase love the informative vids! Keep them up Justin!!!!

A Tracked Lima dragline worked in Merthyr at Taylor Woodrow site, in the late 70,s no idea what model it was I was very young, love diggers all my life. At night it would swing its boom around with lights on, I loved watching it, it looked a bigger model than this in video, big wide grey jib at base of cab.

@espeescotty Thanks. One thing I always work to do is get the right angle on a machine for a good vantage point.

@Stokeypower Well you need to drill and blast for any machine to dig through solid rock. A bulldozer is used to keep the floor clean around the dragline.

Awesome video of such huge plant, we used to have some draglines locally, operated by Celtic energy. I assume the Marion is electrically powered? Could you do a video of how they get the power to the machines? I've always wondered how they manage to get the cables to the working face and where they get the power from. Thanks.

So very cool! Point shooting is great! And itself excavator - grandiose!

@Bauzaunvideos Thanks, and yes that's the purpose of the tires along the dragline boom. It's a very common method.

Can recall 3 machines like this working Jeddo.

@blinko656 No thats the speed of a 7400. It's a huge expensive project to put modern upgraded motors in a machine like this, let alone the fact of having to rewire the entire machine. 7400's a pretty fast machine though.

One hoist and drag rope, cool!

@Mulletsrokkify Sure. Yes this 7400 is electric powered. Well like with anything, power has to come from power lines which run on telephone poles onto the jobsite to the transformers and substation. From the transformers runs the electric cable down to the dragline to give it its power.

Rarely are scrapers used much in Pennsylvania for mining. I've only been to one operation I can think of that was using scrapers to move the pre-strip the clay.

@Bomaz727 Thanks! 12yd on the 7400 and 7yd on the Lima

@xpack10034 All job sites are different and it depends on how deep the coal seams are and how they run, also a preference on what machines to use that will make the job more efficient. Draglines are cheaper to run than a shovel and truck setup.

Love that 2400, listen to that governor on the Cat. Maybe you could stand behind the operator and have a conversation with him while he works......bet he's an old timer too. Thanks

@mgmg385 Cool. No haven't seen any P&H draglines in my travels

Do these machines capture the rotational energy at all in flywheels as they brake the swing motion? It seems that must be half their energy expenditure, swinging to and fro.

Nice video! Is it normal to use a dozer to rip up the groud for draglines? Or do they drill and blast if the groud gets to hard?

Depends on the job and what you’re doing. Crawler is much more versatile than a walker.

That is some loaded buckets!!!!!! Good operators!!!!

I watch the video and I see two different ways to move the machines. A walker and track. Which is the better of the two?

Awesome views of those machines in action! How large were the buckets.

have you ever seen anything like a ph 757 dragline there was one about 5 miles from my house till it was broken down too work in a mine in america

@edktm I will see what I can do. I do have a video from inside a 2400B on my channel if you haven't seen it.

Hi thats an awesome video. Are there Tires mounted on the boom to prevent the noise of the hoist cable when it swings up an down?

do they ever use scrapers for overburden removal? or is it all frontshovels/ excavators and the such. great vid like usual.

Ok thats makes sence but I can t imagine how a drag line can go further away from iself without digging deeper or towards it.

The sad part is those kind of people just put a bad impression on honest people who just want to look at or take pictures of the equipment.

Nice video. I got one question. how do they continue? I mean the 7400 has to dig towards the pile. will they throw it further back or are they finished after they dug the hole up to the pile? I dont know this method.

@farmboy26ful Thanks, will do man!

Great vid! I know Cat bought Bucyrus, but will any of the machine specs change like the size or operating systems?

Yep, it takes alot of convincing sometimes when you are talking to a guard or the mining company. It is hard for them to believe, especially these days with the uneducated green movement, that there are still people out there that love these iron beasts and will treat them with respect.

Why are the tires on the boom?

@redheadedduckhunter I don't think for now, but only time will tell.

why not use cat trucks an backhoe

How big are the bucket chains Justin.

rehandling you mean
