chippers on rail sites

Recommended Posts

any chipper getting ballast build up in the tracks will come unstuck , the one we hired was brand new the nudge bard linkage on the feed hopper snapped after about 3 hrs , those crazy slap buttons on the side lasted ..oh.....about 10 minutes , when manouvering through trees .

and ive heard real bad news about the eltericals on them , however like I said its ability to work on banks is very good

 

It's only a small component that attaches to the bar so easy enough to replace, if a little annoying.

 

The mushrooms (palm switches) are a disaster, it wouldn't be so bad if just the domes could be replaced but you seem to have to replace the whole switch (80 quid from GM, 40 elsewhere).

 

Mk 1s start on the button, mk2s seem to need quite a bit of churning over.

 

The advantage of the safetraks is where they will go during normal running but this is becoming a bit moot with ALO working rules.

I love the comments about it being the manufacturers fault when bits get knocked off of a machine through misuse/abuse. The mushrooms are protected by a steel cover from small snags etc, so how are you smacking them off?

 

Do you blame Ford when you knock the Transit door mirrors off on parked cars? Do you blame Toyota when the HiLux slides into that snowy ditch?

 

The red safety bar is a critical component on any woodchipper - so why would you jeopardise your working day by rendering the machine unusable.

 

For the record - I was looking at other makes in a Network Rail yard to see that the knee bar didn't work on one make as it had been bent and on another make, it did not locate the spool in the "Stop" position because it wasn't adjusted properly and neither make complied with the regs as set down by the HSE because they required too much force to use them.

It is true about network buying new greenmechs unsure on the numbers but there great,all custom built for the railway with light towers and winches attached.we used one of them last week and the only thing I could fault it on was the tracking system was a little slower than the older models but still not as slow as the tw190

well pete the buttons do protrude in a way that make them very vulnerable , as for the nudge bar..we didn't alter it . we actually had to do something else until a fitter had come down to us and fix it. my niggle is nothing to do with wing mirrors or snowy ditches , more a of a view of what I think to be a weak point in the machine . just for the record I wouldn't blame ford or Toyota if id done that...but id be straight back there if the wheel fell off a knew truck

Fair comment Karl ref the truck, not a good analogy from me.

 

Do the buttons on other makes get knocked about? We use those buttons as they are easily obtainable and robust enough for general usage with the cover on but they are not made to be rubbed against a wall or tree - but then, neither are those fitted by TW or Jensen. The safety bar is designed and manufactured to specifications set down by the HSE, a set up that all suppliers (should) comply with. They control the safety side of the infeed and enables the operator to safely disable or reverse the rollers. They were not designed to act as a scoop in a ditch or an anchor point for ropes etc. While I understand and appreciate your comments, if they bust - ask yourself who bust it and how and why.

you sure it was not a QTS chipper as I know they have had there chippers built that way.. NWR have a safetrack at York and Newcastle, but they are not modified in any way and have to cover all of north.. That's the proper north not Manchester to the southies....

The buttons are in a bad place, mount them on top as TW did or in a recess as when trying to get through gaps they do get knocked off...

We run 2 safe tracks and we're told we couldn't use them on line blockages unless they were fitted with the back up electrical drive system , so they can be moved in event of breakdown , they are fine on everything else. We were quoted £2000 per machine to have them retro fitted so ours won't be on any line blockage work

Network Rail brought a number of GreenMech STC1928 with lighting towers, winches and the electrical recovery motor. But then, so have a number of other people also got 1928STC this year too.
