Hardly known in the industry at the time, Hitachi took a big leap and recognition when they created the 801.
This one looks like it's still in good operating condition. Thanks for the presentation Justin, very much appreciated.
Very true! This machine was what put Hitachi on the map.
loved all these machines since i was a little boy.
Me too! 😅
I'd like to meet this PA Mining guy someday!! He sure is a smart feller!!
Anyone else dig the way ole boy walks heavy and stomps on the machine when mounting up? Reminds me of crawling up on equipment back in the day
It's all part of the fun of climbing up on something big 😎
A great tour!
Enjoyed the good views and great information!! This shovel brings back memories.
Glad you enjoyed it! 😀
Interesting video, thank you.
Glad you enjoyed it. 😃
Old but a true workhorse...still much respect!
950 HP at only 1000 rpm. That’s pretty impressive. Rugged looking unit. Thanks Justin, keep em coming. 👍👍🇺🇸
Thanks buddy, will do 😎
It looks like this machine has been well maintained.
Other than all the leaks😂
A rock quarry in my area still uses an UH 801 they must be tough
Thanks, Pal and the one here is a EX-2000 but their power trailer burned from the 3-phase transformers right on to the trailer. MSHA might make them rewire from the motors out. Down about a year..Glad I'm mowing grass. God Bless Yall
Far out you'd have sore shoulders from mixing cakes with those joysticks all day 😂
Oh guaranteed on this old girl!
Beautiful video
Thank you 😃
Thanks PAmining for posting this outstanding video. That UH-801 is a real classic piece of heavy equipment. I consider this particular model to be the 2nd generation of large hydraulic excavators. This Hitachi arrived on the mining/heavy construction scene after the Poclain 1000, Warner & Swasey H-1900, P&H 1200, and Koehring 1266d,and 1466 units were pretty much gone. This particular UH-801 looks like it’s in good overall condition. Do you know if it’s still on active duty?
Yes! A late comer but definitely made a name for itself! Unfortunately no this machine was scrapped not long after I filmed it ':(
The older shovel operators I worked with always said the 801 was a very slow machine, especially when swinging from the face to the truck
Interesting!
Thanks again for the tour! Wonder how manufacturers determine when to put swing brakes on these bigger machines. Is it more so for the long boomed drag lines? Or are they also a feature on the excavators?
Excellent documentary once again PA 👍👍👍 Is this machine the forerunner to the EX1800?
Yes it is! Thank you! 😁
What can a hydraulic shovel ,like this one do that a rope shovel can't. Another great video sir!
@mikekopie9897 Great Question. I’m pretty sure that the main difference between the two types of shovels is that the hydraulic unit is better suited to digging. Because its bucket can articulate in a greater range than the rope unit.So in tough digging conditions the hydraulic shovel can exert greater prying forces. The rope shovel excels in loading. It will deliver excellent production when loading very well blasted material. You will notice when a rope shovel is working at the face, the bucket tends to scrape along without the kind of selective digging ability that the hydraulic machine offers. So overall, the choice of which type of machine to use, will be based mainly on the actual digging conditions,as well as the material itself.On a site with very difficult conditions, like poorly blasted rock formations, I’d definitely opt for the hydraulic shovel.
Take Care.
Thank you for that well explained answer. Sounds like you been there done that. My thought was hydraulic shovel operating costs would be substantially higher with the complexity of the machinery. Rope shovel seems very simple in comparison. But like you said digging conditions dictate what will be efficient for the companies needs.
@@mikekopie9897 Thanks for your reply. I appreciate it. I just want to provide a little more information for you concerning mining shovels. I’m going to base my comments on the larger size shovels used in mining.If a mining company requires new equipment for overburden removal, they will definitely be considering how many years the mine will operate.If the lifespan of the mining project is estimated at less than 10 years, then it makes sense to acquire hydraulic machines.But if the mine is a long term operation, ( such as 20 years), then the normal decision would be rope shovels. This is because the typical high capacity rope shovels are pretty much guaranteed to last for a 20 year period. Just to be clear,I’m referring to machines such as the P&H 4100XPC.That size rope shovel is a huge investment, but with consistent, and excellent maintenance, it should definitely be highly productive for twenty years or more. The reason that the hydraulic shovels or backhoes can’t last that long is due to fluid contamination. There will always be some amount of abrasive material that enters the hydraulic system, either from degraded seals, or other points of entry. Over the years that wear starts adding up even though the entire hydraulic system has been well maintained. The top tier manufacturers have made big improvements over the last 10-20 years. I recently read a brochure about a huge Liebherr mining excavator that states service life should be 80,000 hours.That is the most I’ve ever heard of for a hydraulic machine.That amount of hours basically is equivalent to about 13 years of service life.That would be based on approximately 6,000 hours per year. I hope you found this information interesting. Take Care Sir.
Great video!! However, definitely doesn't look like a mining operation. I see cars passing nearby on a local road. Maybe a highway job or large shopping center project? Can you reveal it's location? I'd love to get a picture from the nearby road if it's within driving distance of my location.
You've obviously never been to a Pennsylvania Coal mine 😁 We mine very close to residential areas, highways, and commercial regions. Thanks!
Machine was made in the same year I was.....and this baby is in better shape than I am. 'Scuse me as my pride bleeds out....
Hahaha 😂 no worries man! Thanks
Hopefully can see how she work after nearly 38 years
Ba bam
Is this machine still in operation or has it been taken out of service?
This particular unit was scrapped not long after I filmed it. Parts availability led to its decline.
Hitachi is the Land Cruiser in the excavator world
What would be the factors that would denote either a front shovel or back hoe configuration? Thanks so much for sharing. Your channel "rocks"... LOL
Front shovel is what is featured in the video, backhoe would be like a typical excavator
A shovel can load rock or material on the “floor” with a truck and doesn’t have to sit on a pedestal like a backhoe. When I worked in mines in Indiana they always used a shovel but the mines I worked at in Kentucky usually used a backhoe when they didn’t use a front end loader and it always seemed to me that a shovel got way more production than a backhoe
@@TJV83 gotcha. Thanks for the info TJ...
One factor I have seen in the past is that backhoes can be used to dig unblasted rock better. They can also dig more selectively than shovels if geological is complex
Haha thank you!! 😁
wish you would stand beside it to get for a better size you might tell us the height and width but that does.nt take in the whole machine
Justin has an odd way of speaking / explaining things . Lol.
I like it, he sounds very enthusiastic.
😃😎
