Problems solved by technology

[0005] However, there is the problem in this respect that it is difficult to access components such as the internal combustion engine, the pump, the radiator or other components arranged in the central region of the superstructure
In particular, this is very impractical in the maintenance of components that are set
Also, due to lack of space, it is no longer possible to add new or additional components to the superstructure of the excavator for the operation of the excavator, or it can only be achieved by omitting other components

Embodiment Construction

[0031] figure 1 with 2 The wheeled excavator 1 shown in has a chassis 2 and a not shown superstructure in a conventional manner. The chassis 2 has a wheeled excavator floor provided with a front axle 4 and a rear axle 5 . On the chassis 2 , the superstructure is placed on a swivel assembly 3 in such a way that it can rotate relative to the chassis 2 about a vertical axis of rotation. In addition to the operator's cab and boom, the superstructure, not shown, has a number of components including the internal combustion engine, pumps, radiators, and the like. The counterweight can be arranged in a known manner in the rear region of the superstructure.

[0032]According to the invention, the two fuel containers 6 have been relocated from the superstructure to the chassis 2, where they are fixedly arranged in figure 1 with 2 wheeled excavator 1. In this respect, a corresponding fuel container 6 is positioned to the side of the chassis 2 between the front axle 4 and the rear a...

Abstract

The present invention relates to an excavator having an undercarriage, a superstructure and an internal combustion engine for the drive of the excavator arranged in or at the superstructure, with at least one fuel tank for the supply of the internal combustion engine with fuel being arranged in or / and at the undercarriage of the excavator.

Description

technical field [0001] The invention relates to an excavator having a chassis, a superstructure and an internal combustion engine arranged in or at the superstructure for driving the excavator. Background technique [0002] Excavators typically have a chassis and a superstructure where other components such as the engine, pump, radiator and fuel tank are positioned on the superstructure in close proximity to an operator's cab and boom. In this specification, both wheeled excavators and crawler excavators are listed as excavators, which are arranged on corresponding excavator chassis. However, the subject of the invention also relates to crawler cranes and other items of working equipment with a corresponding design including chassis and superstructure. [0003] All these types of installations have in common that, due to the maximum transport dimensions, only limited space is available for them on the superstructure. Therefore, the construction space available on the super...
