CONSTRUCTION MACHINES AND FUEL TANKS FOR CONSTRUCTION MACHINES

摘要

Leveled fuel levels in a fuel tank (60) disposed at an undercarriage (16) of a construction machine (10) may ensure that the total fuel volume of the fuel tank (60) may be accessible. The fuel tank (60) may comprise a first fuel compartment (62) and a second fuel compartment (64) fluidly connected to the first fuel compartment (62) and disposed at higher altitudes than the first fuel compartment (62). Furthermore, the fuel tank (60) may comprise at least one step integrally formed with the first fuel compartment (62) or second fuel compartment (64) for facilitating entrance to an operator station (22) of the construction machine (10).

主权项

1. A construction machine comprising:
an undercarriage; a superstructure comprising an internal combustion engine; a swivel configured to rotatably mount the superstructure onto the undercarriage; and a first fuel tank disposed at the undercarriage, the first fuel tank comprising: a first fuel compartment defining a first convex volume including a most lower point, the first fuel compartment being configured to provide fuel to the internal combustion engine; a second fuel compartment defining a second convex volume including a most lower point, the second fuel compartment being configured to receive excessive fuel from the internal combustion engine; and a fuel passage configured to fluidly connect the most lower point of the second convex volume to the first convex volume, such that fuel within the second fuel compartment is enabled to drain the second fuel compartment into the first fuel compartment.
