MAGGIORE STABILITÀ DELLA MACCHINA E CARICHI MAGGIORI

I cingoli hanno un’area di contatto con il suolo molto più ampia rispetto alle catene forestali.

Vintaggi:

MIGLIOR ADERENZA E TRASMISSIONE DELLA FORZA

Indipendentemente dalla superficie su cui viene utilizzata la macchina da lavoro, i cingoli GreenTrack offrono una buona aderenza e una maggiore trasmissione della forza.

Per un’aderenza ottimale dei cingoli con lo pneumatico si consiglia di utilizzare pneumatici dotati di un canale speciale in cui vengono inseriti i cingoli.

DURATA PIÙ LUNGA DEGLI PNEUMATICI

Una parte importante della macchina sono gli pneumatici che rappresentano un costo elevato. Con i cingoli la vita degli pneumatici si allunga fino al 60%.

I cingoli GreenTrack svolgono un duplice ruolo nella protezione degli pneumatici:
1. Grazie alla forma del profilo le ruote non scivolano all’interno dei cingoli, il che riduce l’usura del battistrada dello pneumatico.

2. Proteggono il battistrada e la parte laterale da oggetti appuntiti (pietre, massi) che rovinano il profilo dello pneumatico.

MINOR IMPATTO SUL SUOLO FORESTALE

In una società in cui la cura per l’ambiente sta diventando sempre più importante, non possiamo ignorare l’impatto delle macchine forestali sul suolo forestale. A tal proposito nel 2010 è stato condotto uno studio presso la Facoltà di biotecnica dell’Università di Lubiana (Slovenia). Parte dello studio è anche il grafico sottostante che mostra una ridotta pressione nominale sulla superficie tra il 30-50% se vengono utilizzati i cingoli invece delle catene forestali.

SELEZIONE DEL MATERIALE

Abbiamo scelto profili laminati e non pezzi fusi perché la ricerca di esperti ha dimostrato che solo i profili laminati ottengono l’appropriata struttura fine del materiale che ci consente di ottenere in modo uniforme e adeguato durezza e tenacità su tutto il profilo.

Abbiamo scelto l’acciaio al boro che nel processo di tempra consente una durezza uniforme su tutta la sezione trasversale del profilo. Allo stesso tempo raggiunge un rapporto ottimale tra durezza e tenacità. La durezza è importante a causa dell’usura superficiale dei cingoli, mentre la tenacità garantisce che il materiale non sia fragile e non si spezzi con carichi più elevati.

• Nello sviluppo dei cingoli è stata prestata particolare attenzione alla scelta del materiale. Per un uso ottimale dei cingoli, il materiale deve essere abbastanza duro e resistente da fornire resistenza all’usura e agli urti e quindi garantire una lunga durata dei cingoli.
• Le saldature di qualità sono cruciali per l’utilizzo e la durata della vita dei cingoli.
• Con l’acciaio speciale al boro abbiamo incluso tutte le caratteristiche che il materiale richiede per una produzione e un uso di qualità dei cingoli.
• I cingoli sono trattati termicamente per raggiungere una durezza di 42-45 HRC. Ciò garantisce resistenza all’usura e allo stesso tempo il materiale non è troppo duro e non si sgretola su superfici dure e rocciose.
• Saldatura con robot di saldatura.
• Rigoroso controllo di qualità di ogni singolo prodotto.

LE GIUNZIONI

Sulla base di analisi e test abbiamo determinato i diametri ottimali delle giunzioni che garantiscono un’adeguata trasmissione della forza e non aumentano il peso dei cingoli. Abbiamo sviluppato giunzioni da 26/30 o 30/35 mm.

Molto spesso le giunzioni inserite sono 26/30 che resistono ai compiti più difficili e consentono un uso ininterrotto. Per prolungare la vita dei cingoli ovvero per l’utilizzo in condizioni estreme si consiglia una giunzione da 30/35. Con del materiale aggiuntivo si garantisce il trasferimento di forze maggiori ovvero la durata della vita più lunga, mentre il peso dei cingoli aumenta leggermente.

SALDATURA DEI DENTI

Oltre alle giunzioni, anche i denti saldati più esposti sono parti soggette all’usura. Il materiale dei denti è lo stesso dei profili in modo da avere condizioni di saldatura uniformi. I denti vengono saldati in serie prima che i cingoli vengano trattati termicamente per evitare un possibile ammorbidimento locale del materiale. Il punto in cui viene saldato il dente ha una forma speciale che offre un supporto aggiuntivo. Le saldature sono uniformi e continue per garantire lunga durata e utilizzo dei denti. Nella maggior parte dei casi un dente è saldato sulla traversa, alternativamente su ciascun lato.

Su richiesta del cliente possiamo anche saldare più denti in punti diversi e quindi aumentare l’aderenza.

ELEMENTI LATERALI DEI CINGOLI

La funzione degli elementi laterali è:

• Limitare la posizione dei cingoli sullo pneumatico – autocentraggio;
• Gli elementi laterali dei cingoli consentono agli pneumatici di muoversi continuamente all’interno dei cingoli – questo migliora anche l’aderenza tra lo pneumatico e il cingolo e garantisce una guida più fluida;
• Stabilità laterale dei cingoli – durante la guida su pendii, gli elementi laterali forniscono un supporto necessario sullo pneumatico;
• Protezione laterale dello pneumatico – protegge lo pneumatico da oggetti appuntiti e usura eccessiva.

Minimal space between the tyre and the bodywork is a=15 cm

ENHANCED STABILITY OF THE MACHINE AND GREATER LOADS

Tracks have a much larger contact area with the ground compared to forestry chains.

Advantages:
– Greater contact area with the ground;
– Uniformly distributed force on the surface;
– Constant grip with the surface;
– Increased stability reduces machine tilting;
– The work machine is more stable when driving over uneven surfaces;

ENHANCED TRACTION AND TRANSMISSION OF FORCE

Regardless on what ground you use the work machine, the greenTrack tracks provide good traction and greater force transmission.

For optimal traction of the tracks with tyres, it is recommended to use tyres with a special channel, into which the track “rests”.

PROLONGED SERVICE LIFE OF THE TYRES

An important part of the machine are the tyres, which represent a substantial cost. With tracks, the lifetime of the tyres are prolonged by up to 60%.

greenTrack tracks have a dual role in the protection of the tyres:
1. The shape of the pro le prevents the wheels from slipping inside the track, while also contributing to the reduced wear of the
tyre tread.
2. Protection of the tread and the sides against sharp ob- jects (stones, rocks), which “cut” into the tyre pro le, thus destroy- ing it.

LESS IMPACT ON THE FOREST FLOOR

In a society where caring for the environment is becoming increasingly important, we cannot ignore the impact forestry machinery has on the forest floor. To this end, the Biotechnical Faculty of the University of Ljubljana conducted a study in 2010. The graph below shows a part of the study, i.e. reduced nominal ground pressure between 30 and 50% when using tracks instead of forestry chains.

MATERIAL SELECTION

We have chosen rolled pro les, not castings, as various researches conducted by experts have shown that only rolled pro les achieve an correspondingly ne structure of the material, ensuring an even and adequate hardness and toughness through the entire pro le.

We have chosen boron steel, which achieves an optimal ratio between hardness and toughness after the process of hardening. Hardness is important because of the abrasion of the tracks, while toughness ensures the material is not fragile and does not crack during higher loads.

• We have put a lot of emphasis on the selection of material during the development of the tracks The optimal use of the tracks requires sufficiently hard and tough material, allowing abrasion and impact damage resistance, thus providing a longer lifetime
• Quality welds are essential for the functionality of the product and the lifetime of the track
• A special boron steel includes all the characteristics the material needs for the quality manufacture and use of the tracks
• The tracks are heat-treated until the hardness 42–45 HRC is achieved This ensures abrasion resistance, while at the same time the material is not too hard to break on hard and stony surfaces

LINKS

A vital part of the tracks are the links. Based on analyses and testing, we have determined the optimal diameters of the links, which provide the appropriate transmission of forces and do not increase the weight of the track. We have developed Ø 22, Ø 26 and Ø 30 mm links.

Most commonly integrated are Ø 26 links, which are designed to withstand the hardest tasks and enable
a smooth application. To prolong the lifetime of the track or enable its use in extreme conditions, we recommend the Ø 30 link. With additional material, it ensures the transmission of greater forces and a longer lifetime, while only slightly increasing the weight of the tracks.
If the total weight of the track is more important than the force, i.e. during operation, it is possible to install slightly lighter Ø 22 mm links.

WELDING THE TEETH

In addition to the links, welded teeth are also under a great load and the most exposed. The material is the same as for the pro les, ensuring the same welding conditions. The teeth are serially welded prior to the heat treatment of the track in order to avoid any local softening of the material. The place where the teeth are welded is of a speci c form, providing additional support. The welds are even and continuous, ensuring a long lifetime and usefulness of the teeth. In most cases, one tooth is welded on the crosspiece – alternately on each side.

At the customer’s request, we can also weld more teeth, thus increasing the grip.

SIDE ELEMENTS OF THE TRACKS

The function of a sidepart is:

• To restrict the position of the track on the tyre – self-centring;
• The side elements allow the tyres to move within the track at all times – this also enhancing the grip between the tyres and the track which ensures smoother driving;
• Lateral stability of the track – when driving on slopes, the side parts ensure the required support on the tyres;
• Lateral protection of the tyre – protects the tyre against sharp objects and excessive wear

Minimal space between the tyre and the bodywork is a=15 cm

VEČJA STABILNOST STROJA IN VEČJE OBREMENITVE

Gosenice imajo veliko večjo kontaktno površino s tlemi v primerjavi z gozdarskimi verigami.

Prednosti:

Večja kontaktna površina s tlemi.
– Enakomerno porazdeljena sila na podlago.
– Konstanten oprijem s podlago.
– Povečana stabilnost zmanjša nagibanje stroja.
– Delovni stroj je bolj stabilen pri vožnji čez neravnine.
– Transport večjih bremen.
– Hitrejša vožnja.
– Manjša poraba goriva.

BOLJŠI OPRIJEM IN PRENOS SILE

Ne glede na kakšni podlagi uporabljate delovni stroj, vam GreenTRACK gosenice ponujajo dober oprijem in večji prenos sile.

Za optimalen oprijem gosenice s pnevmatiko se priporoča uporaba pnevmatik, ki imajo izdelan poseben kanal, v katerega se prilega gosenica.

DALJŠA ŽIVLJENJSKA DOBA PNEVMATIK

Pomemben del stroja so pnevmatike, ki predstavljajo velik strošek. Z gosenicami se življenjska doba pnevmatik podaljša za 60%. GreenTRACK gosenice imajo dvojno vlogo pri zaščiti pnevmatik:

1. Zaradi oblike profila, kolesa ne spodrsavajo znotraj gosenice, kar zmanjša obrabo tekalne
površine pnevmatike.
2. Zaščita tekalnega in stranskega dela pred ostrimi predmeti (kamenje, skale), ki uničujejo profil pnevmatike.

MANJŠI VPLIV NA GOZDNA TLA

V družbi, kjer je skrb za okolje vse pomembnejša, ne moremo mimo vpliva gozdarskih strojev na gozdna tla. V ta namen je bila opravljena študija Biotehniške Fakultete Univerze v Ljubljani, leta 2010. Del študije predstavlja tudi spodnji graf, ki prikazuje zmanjšan nominalni tlak na podlago med 30- 50%, v kolikor uporabljamo gosenice namesto gozdarskih verig.

IZBOR MATERIALA

Izbrali smo valjane profile in ne ulitkov, ker so raziskave strokovnjakov pokazale, da le pri valjanih profilih dobimo ustrezno no strukturo materiala, ki nam omogoča enakomerno in ustrezno trdoto in žilavost preko celotnega profila.

Izbrali smo borovo jeklo, ki pri postopku kaljenja omogoča enakomerno trdoto čez celotni prerez profila. Hkrati pa omogoča optimalno razmerje med trdoto in žilavostjo. Trdota je pomembna zaradi površinske obrabe gosenic, žilavost pa, da material ni krhek in pri večjih obremenitvah ne poka.

Podatki o materialu:

• Pri razvoju gosenic smo poseben poudarek namenili izbiri materiala Za optimalno uporabo gosenic mora biti material dovolj trd in žilav, da omogoča odpornost proti obrabi in udarnim poškodbam in s tem zagotavljamo dolgo življenjsko dobo.
• Kakovostni vari so ključnega pomena pri uporabnosti in življenjski dobi gosenice.
• S specialnim borovim jeklom smo zajeli vse karakteristike, ki jih material potrebuje za kakovostno izdelavo in uporabo gosenic
• Gosenice so termično obdelane do trdote 42-45 HRC. S tem je zagotovljena odpornost proti obrabi, hkrati pa material ni pretrd da bi se na trdih in kamnitih podlagah krušil.

VITALNI DEL GOSENIC SO POVEZAVE

Na podlagi analiz in testiranj, smo določili optimalne premere povezave, ki zagotavljajo ustrezen prenos sil in ne povečujejo teže gosenice. Razvili smo povezave Ø 22, Ø 26 in Ø 30 mm.

Najpogosteje so vgrajene povezave Ø 26, ki vzdržijo najtežje naloge in omogočajo nemoteno uporabo. Za podaljšanje življenjske dobe gosenice oz. za uporabo v ekstremnih pogojih, predlagamo povezavo Ø 30. Z dodatnim materialom zagotavlja prenos večjih sil oz. daljšo življenjsko dobo, hkrati pa se teža gosenic nekoliko poveča.
V kolikor je skupna teža gosenice pomembnejša od velikosti sile pri obratovanju, lahko vgradimo tudi nekoliko lažje povezave Ø 22 mm.

VARJENJE ZOB

Poleg povezav so zelo obremenjeni deli tudi varjeni zobje, ki so najbolj izpostavljeni. Material je enak, kot za profile, da imamo enakomerne pogoje pri varjenju. Serijsko so zobje varjeni pred termično obdelavo gosenice, da se izognemo morebitnemu lokalnemu mehčanju materiala. Mesto kjer privarimo zob ima posebno obliko, ki nudi dodatno oporo. Vari so enakomerni in zvezni, da zagotovimo dolgo življenjsko dobo in uporabnost zob. V večini primerov je na prečko navarjen en zob – izmenično na vsako stran.

Po želji stranke, pa lahko navarimo tudi več zob in s tem povečamo oprijem.

STRANSKI ELEMENTI GOSENIC

Funkcija stranskih elementov je:

• Omejiti pozicijo gosenice na pnevmatiki – samocentriranje.
• Stranski elementi gosenic omogočajo, da se pnevmatike gibljejo ves čas znotraj gosenice – s tem izboljšamo tudi oprijem med pnevmatiko in gosenico in zagotovimo mirnejšo vožnjo.
• Stranska stabilnost gosenice – pri vožnji po strminah skrbijo stranski elementi za obvezno oporo na pnevmatiko.
• Stranska zaščita pnevmatike – ščiti pnevmatiko pred ostrimi predmeti in prekomerno obrabo.

Minimalen prostor med pnevmatiko in karoserijo je a=15 cm
