how to use a wheeled excavator

[barracane]

come utilizzare un escavatore gommato?

Scusate la domanda faticosa, in un forum di escavatori, ci sono molti video online su come usare il macchinario, non ne ho trovati su come si usa l'escavatore gommato, i comandi, come viaggia, come avanza, come si guida su strada e come usare in cantiere se qualche amico paziente potrebbe gentilmente fare un video o una panoramica dell'abitacolo, come guidare su strada come posizionarsi in cantiere come usare i limiti e le cose da non fare nella mia zona mai viste grazie saluti.

in cosa differisce l'escavatore gommato dai tabarelli o dai raccogli rottami spider grazie.


:fischio:I honestly associate them better with versatile cranes than with excavators. In my opinion, the tracked excavator is more stable and balanced, climbs slopes better, the wheeled one is clumsier, more suitable for road maintenance, but that's my opinion, thanks.

Smoothly,
Axle locks and working brakes,
I`ve driven some with forward and reverse on a lever like a dumper then one pedal to regulate speed, and ones with two pedals one forwards, one backwards,
Some have a hi/low that can be used on the move, some have a hi/low gear that can only be changed while stationary, some have both,
The steering will be back to front, with the upper structure spun around,
Tyre types make a big difference to stability, your generally sitting higher for the size of excavator so any movement is magnified,
Try to avoid digging over the steering axle end to reduce stress on king pins (impossible on 4WS) stabilisers and blade will help a lot if used.
If picking up on bucket and blade to flick mud off the tyres, shut cab window

Couldn’t have put it better, Craig. That just about covers it.

Yes the only thing missed is that you push the service breaks all the way down and the pedal will lock and stay down which should also engage your axle locks if there set to auto.

Make sure you know how the axle locks work and your familiar with it before you try to work too hard

May aswell put it here as we seem to like derailing threads.
How is it that in Europe they manage to get ducks into alsorts of building sites. It's been a while since I've been to France but I remember in the past seeing ducks everywhere.
I know that we simply can't use them as much on highways work in this country due to the restrictions placed on us by chapter 8. But is our mud stickier than there's as they seem to get them in some incredible places that I couldn't imagine anyone in this country wanting to take them.

I only ever see them in waste handling sites.

The company I subbed to for several years used to put me in some rare situations with a Cat 206. It just had a blade. We had a 212 that had a blade and legs and it couldn’t get around as well when conditions were bad. I worked on batters with it (hairy), pulling cables and pipe runs through virtual swamps, it was light relief doing a bit of road work.

I've never driven one so no clue about them but it strikes me as very odd their nigh on complete absence. Especially with the places you have described taking them. The backhoe seems to be disappearing throughout the western world yet mainland Europe have plenty of ducks. Why is it they don't work for us. I mean new build sites round here get crushed up as soon as possible to allow the telehandlers to run so surely it ducks on finishing works would be better than it rubber tracks.

Because (round here) the only machines folk seem capable of hiring on big sites are a 13t or u27 and 6t dumper nothing else in between.

Credo che l'escavatore venga utilizzato dal lato lama per dare maggiore stabilità alla macchina e proteggere le parti inferiori della macchina. se spingi lateralmente hai problemi con il baricentro, il basamento è più stretto, l'assetto della macchina è più sbilanciato e l'escavatore alza la coda. il cingolato è più forte, massiccio e robusto, sotto ci sono i tubi idraulici il gommato ha il cambio e l'invertitore sotto la trasmissione, poi come dici giustamente il ponte dell'asse è sollecitato nei perni dei fuselli, nei freni e anche credo che Se dei rami cadono nell'albero cardanico della trasmissione e l'operatore non è meticoloso si provocano gravi danni. Il veicolo a ruote non è destinato all'estrazione. È più adatto a cantieri stradali o piccoli cantieri puliti per la manutenzione. Per i grandi scavi il TREX è ancora il mezzo cingolato. Faccio un errore tipo detrazione se hai altro da aggiungere ti invito a correggermi grazie saluti.

le ruote sono un serio punto debole della macchina in caso di foratura nel terreno forse sono presenti spuntoni di ferro taglienti, ruvidi, detriti coriacei il cingolo in acciaio è una sicura corazza che rende la macchina più bassa e più equilibrata e stabile

I love my 'duck' .. but you won't beat tracks in the tish (when it's wet)

sei un funambolo un acrobata con quell'escavatore gommato potresti gentilmente fotografare la cabina di pilotaggio e spiegare i comandi come si trasla e si muove come si posiziona correttamente grazie un video sarebbe i migliori grazie saluti.

Amazing machines. But my experience with the Big Duck was not on the side of a hill!!
I can understand why they are used on roadside highway work on tarmac!!

I loved my duck, granted it was a baby at 7tons but the variety of work that could be achieved with that machine was great. Its ability to carry its own attachments and move between jobs (albeit not quickly @ 30km/h) was a big benefit too in my 2 years of driving it we put it on a truck once.

As mentioned above, axle locks and understanding how they work and how the machine behaves in various situations is key, a lot of our work was off-road and I found I used to work over the rigid axle a lot so that I could move around without having to constantly switch the locks on and off. I also found the direction of the tyres made a huge difference to how much climbing traction it had and facing the wrong way around caught be out a few times.

The Mecalac is a little bit unique in its configuration though, not just the boom but the slew ring is central on the chassis so it feels the same regardless of where you are in the rotation of the machine, the wheelbase and machine width are also very close which help the machine feel more consistent when working.

Hugely miss being out on this machine, maybe one day I will be back out there in a Mecalac duck again!

no way would I take the 'Drema on that cross slope - up/down - no probs, but she is tall compared to that little Mec and over twice the weight at 16t wet ... if forced onto a cross slope I always have the bucket 'kissing' the deck, downhill, travelling, VA fully closed, to keep the boom weight back uphill and butt cheeks firmly clamped to the seat

you are a tightrope walker, an acrobat with that wheeled excavator, could you kindly photograph the cockpit and explain the controls, how to move and move, how to position yourself correctly, thank you, a video would be the best, thank you, greetings.

LOL ... there are far better duck op.s than me .. I'm a 'part-timer' ... next time I'm in her i'll get you some pix @barracane

Non credo che la papera di gomma sia versatile e stabile come un cingolato in termini di baricentro e assetto della macchina, non credo sia possibile tracciare strade e sentieri in montagna e collina o costruire e spostare sassi e massi, è più una macchina di servizio per lavori comunali dove è necessario effettuare riparazioni idrauliche con il mezzo cingolato, frantumare il manto stradale, tenere presente che nei centri storici il manto stradale potrebbe non essere asfaltato ma asfaltato, se ci vai con il cingolato, fai una frittata di uova nella cava il gommato si muove goffamente e lentamente se piove e il terreno diventa poltiglia non galleggia e sprofonda sotto il peso il cingolato risale la ripida pende e si fa strada autonomamente, sbaglio?

This is my Landlords Duck. He bought it during lockdown at auction as non runner.The dashboard came back in the back of his car. There was quite a LOT of swearing before it got fixed. Been working every day since on the transfer station though. Odd set up with Tab Boom AND offset. Makes it very heavy on boom which is apparently perfect for waste work and compacting skips. Has a rotating grab on it. Not managed to get a go on it yet though :-(

that's an odd ball ... VA and knuckle - shame the bucket gear is missing ... undercover is the best place for that to be -- otherwise .......

make sure the cab is WATERTIGHT ... this un was on it's third ECU in 7 weeks .... at seeeeeeeeeeeerious cost ... and couldn't find out where the water was coming in and killing them ...

did manage a couple of days digging up my yard for the archaeological survey though
