DESCRIZIONE DESCRIPTION

Forma oggetto del presente trovato un elevatore semovente con retroescavatore. The present invention relates to a self-propelled elevator with backhoe.

Esso ?, nella sostanza, una macchina operatrice combinata di largo e versatile impiego del tipo usualmente costituito da un trattore attrezzato con un dispositivo sollevatore (o una pala meccanica) operante anteriormente e provvisto posteriormente di un escavatore a bracico articolato. In essence, it is a combined operating machine of wide and versatile use of the type usually constituted by a tractor equipped with a lifting device (or a mechanical shovel) operating at the front and equipped at the rear with an articulated arm excavator.

In particolare per quelle applicazioni che utilizzano un dispositivo sollevatore, costituito da un braccio di manovra telescopico collocato in posizione mediana sul telaio del veicolo, si pone il problema di assicurare all 'operatore la migliore posizione sia per la guida del veicolo e la manovra del sollevatore sia per la manovra dell 'escavatore a bracico articolato. Poich? per la guida del veicolo e per la manovra del sollevatore si rende necessario una posizione di guida avanzata mentre per la manovra dell 'escavatore ? necessaria una posizione pi? arretrata che consenta all'operatore di controllare direttamente tutto il campo di azione dell 'escavatore ? stata dottata la soluzione di realizzare due posti di guida separati. Il che, nelle applicazioni note, obbliga l 'operatore a discendere dalla macchina per spostarsi da un posto di guida all'altro. In particular, for those applications that use a lifting device, consisting of a telescopic maneuvering arm placed in a median position on the vehicle frame, the problem arises of ensuring the operator the best position for both driving the vehicle and maneuvering the lift. both for the maneuver of the articulated arm excavator. Since? for driving the vehicle and for maneuvering the lift is it necessary to have an advanced driving position while for maneuvering the excavator? need a position pi? backward that allows the operator to directly control the entire range of action of the excavator? the solution of creating two separate driving seats was devised. This, in known applications, forces the operator to get off the machine to move from one driving position to another.

A questo inconveniente, che limita la capacit? operativa di tali realizzazioni note, si propone di ovviare il presente ritrovato cos? come esso risulta definito nelle rivendicazioni. To this drawback, which limits the capacity? operative of these known realizations, it is proposed to obviate the present invention so? as it is defined in the claims.

Esso si propone inoltre di dar luogo ad un nuovo elevatore semovente con retroescavatore nel quale la sistemazione e la struttura delle varie parti telaio, braccio sollevatore telescopico, escavatore, sia tale da consentire, rispetto alla tecnica nota, un sensibile miglioramento delle condizioni di visibilit? in tutte le situazioni operative. Un vantaggio -fornito dal presente trovato ? costituito dal fatto di offrire una sistemazione sicura e confortevole per l'operatore. It also proposes to give rise to a new self-propelled lift with backhoe in which the arrangement and structure of the various parts of the frame, telescopic lift arm, excavator, is such as to allow, compared to the known technique, a significant improvement in the conditions of visibility. in all operational situations. An advantage provided by the present invention? consisting of offering safe and comfortable accommodation for the operator.

Ulteriori caratteri stiche e vantaggi del rpesente trovato meglio appariranno dalla descrizione dettagliata che segue di una forma preferita ma non esclusiva di realizzazione illustrata a titolo puramente esemplificativo e non limitativo negli allegati disegni in cui: Further characteristics and advantages of the present invention will appear better from the following detailed description of a preferred but not exclusive embodiment illustrated by way of non-limiting example in the attached drawings in which:
