Pegson Tracked Plant Info, Pictures and related questions

A bit of an update on the "venture". The crusher is with its second customer and many other phone calls, good. However the repairs have cost way more than the revenues!!! :Banghead I am not nervous yet i consider all of these repairs as "capitol improvements" i pray they level off soon and the revenues start to overcome the costs. The current issue is the fuel system is being replaced, the engine is a cat c6.6 and it has low psi in the high pressure fuel rail. I have also come up with some interesting potential customers, they need the crusher ASAP and are willing to pay "up front", then i say i still need a credit application and a certificate of insurance and i never get a call back? I "googled" one guy and the first 5 search results that came back were lawsuits!!!:ointhead Oh what fun it is to own your own business.......>>>>>TIO:

I would think having a rental crusher would be a losing battle. I assume most of the companies renting one (especially from a small business like yours) would have little experience operating one. Doesn't seem like something you can toss to a noob w/o having issues. Even if you recover the cost of damages the downtime and loss of rental associated would be costly. I may be way off but I'm not a risk taker.

All businesses could be a losing battle. Businesses are a fine balance of limiting risk and liability while producing revenue. I can recall being a noob once and asking lots of dumb questions, I do believe i can now answer some of these questions for potential rental customers. As far as recovering cost of damages this is standard rental operation but also the rental time loss while repairs are being made (if customer is responsible for repairs) is also charged to the customer, now this is sometimes slightly a gray area perhaps they don't pay for the time it takes for the parts to be shipped but at least while the mechanic is working on it. This crusher rental "venture" may be a loser but my current business plan is to produce as much revenue with no employees at least until that special field mechanic comes to me looking for a job LOL. With no employees i have decided the best way to produce revenue is to buy and rent equipment out, i have chosen track crushers because i know i can't compete with the dealer type renting, i.e. excavators, dozers, loaders etc............TIO

I knew you had it well thought out. I have never been around crushers thank god but can only imagine what a inattentive or inexperienced operator could accomplish. I worked on rental asphalt mills and tub grinders and the memories make me shiver. Glad I didn't own them.

you should always be getting 1st rental up front that way they always pay ahead or before you know it they are 2 payments behind and your crusher broke .

As tctractors suggested earlier renting a crusher complete with operator is the way to go. A good operator can reduce what I refer to as "disaster potential" by a tremendous amount. Personally I wouldn't feel comfortable having a very expensive piece of kit under the control of someone who I didn't have direct control of, if that makes sense.

Last rumor I heard was Cat dropped the 6.6, to many warranty claims, valve train damage after repair, I never worked on one and friends at cat said don't. What's your opinion?

Is the toggle plate in a single toggle jaw crusher the "fuse" the "weak link" ? or is it just a piece of wear metal in a hinge joint? I was taught it was suppose to break apart if the jaw had uncrushable material i.e. tramp iron fed into it> but now i am wondering if this is actually true.......TIO

Extec units are fitted with an alarm switch for when the toggle bends or breaks (the Fuse) but a near blind man can see the big chunks of rubble heading up the main belt without it.

a video of the crusher.....TIO

not to exciting but that is my first ever youtube post. I had to shorten it from 4 minutes to 1 minute for some reason. I will more videos and better ones in the future....TIO

TC you know we have all come on to a job and wondered if the operator was actually blind!!! And exactly what would an alarm do? Operators are trained not to pay attention to alarms because they are always going off for some reason or another! How often does someone actually think that fixing a faulty alarm is a good use of time? LOL......TIO

The inability, lack of Compus Mentus, and total thick un's that I come across constantly, and that is just the bosses or managers is off the scale now, years ago the boss on a site was top draw and new exactly what was going to happen and when, so to expect the workforce to be any better than what they are is realy something that is impossible to discuss on a platform like this, the total daft things I have been around would take up a few gallons of ink to print, so a flashing light or an alarm is not going to stop the crusher working, so my job is very safe as long as things keep at this record low of "dont give a stuff"
The little Blue Beast looks to be on some very easy going in the video, you probably know that the running of a Crusher is best with the jaw set above 40mm and product screened off for the size needed, also crushers work best when they are not leaning to the left or right side, I dont mind a bit of a slope from the feeder end down to the jaws, but I often go to sites and the Crusher is even set up in the wrong spot??anyhow I have spent all last week including the weekend working on a C12+ with the CAT motor, I have been impressed by the owner who is 71 and sharp as a razor, but sadly is let down somewhat by the skins around him that could do thing better and easier, but I am not there to instruct his staff. tctractors

A video of an impactor i replaced the under screen drive motor on.......TIO

Ok, from my advertising I have received many phone calls from people wanting to crush down to 3/4" from 20" with one machine! Obviously there is a market for this which I was not planning on catering to but now I am thinking about it. I can think of a few options 1) rubble master 2) buy and completely refurbish an old jaw/roll duplex plant 3) eagle impactor. The criteria again is easy hauling which to me is one piece under 80,000 pounds. The above video was a customer who rented my jaw to feed this impactor, later deciding my jaw just got in the way and did not really increase production the problem here is the closed circuit impactor is very heavy and cost him nearly as much to haul in and out as it did to rent it for the week they had it! Does anyone have any experience with my three mentioned options? From past experiences I have some huge reservations about massive wear on impactors......TIO

it is possible to crush that much reduction with one machine .but i think it would be more cost effective to crush it with jaw then screen and send overs to an impactor then back to screen

Hi, I did my apprenticeship at Pegson in its original location of Coalville in the uk, Spent time in parts/service/warranty depts. Took an opportunity later to move to their USA distributor to help build the profile over here as well as worked at the NY dealer for a year too. 20 years all in all, I have a lot of general knowledge of the machines and many contacts, Now work for myself, Feel free to contact me if I might be of any help, Email me DRWcrusherservices@gmail.com or Tel 502 777 3167 and my names Danny williams

The toggle plate on a Pegson jaw is designed as the "Weak link" or "fuse" and therefore should fail before anything else does under normal circumstances, however we must remember that these machines are into 5-10-20 years of age now and the chances of the original OEM toggle plate still being fitted are slim, A lot of aftermarket companies copy and sell them based on general appearance, Not necessarily per the spec IE Material type. Most types are Cast and should crack and be checked regularly (Wont necessarily fall out although severe cases did) its possible to crack the toggle plate but continue crushing therefore causing further damage to other areas, Some newer models have a plate type that are designed to bend but all should be made to spec (probably the most important part on the plant that you shouldn't take risks with in that respect)
Other common toggle/shaft failure issues were related to either them not being seated properly upon fitting (Sometimes hear a slap if this is the case)
Or incorrect grease type being used on jaw bearings
Or under greasing
OR over greasing (Can trap the heat in there by doing this)
Greasing schedule and type is very important
If a shaft fractures it isn't necessarily because something went thru the machine that should have caused the toggle to break, Often its related to excessive heat via the greasing issue mentioned above
Another thing to check regularly are the flywheels and alignment, They aren't designed to slip/spin but often do should something go thru the chamber that shouldn't have just due to momentum, So check that the arrows line up and make sure they are torqued up to spec also

Nothing wrong in using general aftermarket wear parts such as side liners/cheek plates etc but be cautious with toggles and jaws
Jaws are designed to fit and operate within weight limitations, Iv'e seen some aftermarket jaws that were almost twice as thick as the originals but maybe not tested or approved by factory for use etc
Also make sure that upon rebuild the outer bearing caps were torqued up accordingly (should have a little nipple on top of the large bolt that holds them down) not certain this has been done prior to every shaft rebuild over the years - Don't want any movement in there
Also the bearings may or may not be per original factory spec/recommendations if they've been changed over the years
And i'd assume the inner bore of the swing jaw would have been checked with each rebuild, Any bearing spin in there could also cause a heat issue and transfer to shaft etc

Here is the picture of the last broken shaft. By far this is the worst I have ever seen, usually you have to get things super clean and sometimes use developer or heat to convince yourself there is a hair line crack.....TIO

This is a premiertrak 27x44 jaw with a c-9? cat engine which the engine has given excellent service.......TIO

Seen shafts crack at the step, hairline- parallel, but not like this.
Heard of a situation in where if the big rock didn't break, pushing it in with the bucket would do the trick.

Unfortunately your pic looks like it, or potential over-grease / no-grease / wrong grease ?

Should be EP2 grease and a good idea to monitor the temps around the bearing houses, Look for bubbling paint etc, Also important to stick to greasing schedule just incase. its possible it was simply a bad shaft, I vaguely recall we always used to bring the shafts in from the OEM in England, But when we needed one quickly about 5-6 years ago they allowed us to have them made locally to the drawing (Which was fine) but the manufacturer wasn't able to source the exact same material type, He used the nearest he could find, Shouldn't have made any difference but since that time who knows what people are having them made out of?
