Definitions
- the invention relates to a mobile excavator comprising an undercarriage having at least two axles.
- Mobile excavators are equipped as a wheeled vehicle and as a rule have two axles. They are thus roadworthy and can drive independently to their location of use on their own.
- the maximum axle load for driving axles is currently 11.5 metric tons (t) and for non-driving axles 10 t.
- the maximum permitted excavator weight for road travel is limited to 18 t with two axles.
- At least one bogie or dolly is fixedly flanged to and/or can be coupled to the mobile excavator (travel unit or revolving superstructure).
- This bogie or dolly has at least one further axis so that, in addition to the two axle lines of the conventional mobile excavator, at least one axle line or any number of desired axle lines are added via the bogie or dolly fixedly connected to the mobile excavator.
- the mobile excavator can be operated on the public highways with a total weight of more than 18 t.
- the at least one bogie can be flanged on with torque stiffness and/or can be coupled on.
- a fixed connection is thus established between the mobile excavator and the bogie so that the load of the mobile excavator is distributed here in the same way over the axles of the travel unit or of the bogie which are made available correspondingly.
- the couplable bogie can be removed for the use on the construction site in order to be flanged back on for the next road transport.
- the at least one bogie can also be flanged on via a biased spring unit.
- the at least one bogie can be arranged at any desired position of the mobile excavator. It can, for instance, be arranged at the front of the travel unit, at the rear of the travel unit, at on or both sides of the travel unit and/or beneath the travel unit and be fastened to it.
- a plurality of bogies can naturally be fastened to the travel unit simultaneously within the framework of the invention in order to achieve an optimized axle load distribution.
- the bogie can advantageously have at least one centrally arranged axle line with single tires or twin tires.
- the bogie can have at least one axle line with two single tires or twin tires arranged off-center.
- the wheels arranged at the bogie can be fitted with a brake.
- the wheels arranged at the bogie can also be steerable.
- the wheels arranged at the bogie can have a spring suspension.
- the axle(s) arranged at the bogie can furthermore be liftable.
- a mounting device can particularly advantageously be additionally present on the at least one bogie for the mounting and for the transport of attachments, tools and the like.
- a mounting device (bar or counter-piece to the fast-change adapter) can furthermore be attached for better handling.
- the at least one bogie can be connected to the travel unit via other attachment parts such as the support plate.
- the bogie can also be fastened to the mobile excavator via the equipment, for example the bucket fastened to the stick.
- the bogie can here be made in the form of a support wheel.
- the axle load reduction takes place here in that part of the equipment weight lies on this support wheel or on the bogie.
- the lift cylinder of the equipment can be connected to the support on the bogie in a floating position for the transport version. Balancing is thus also possible on uneven ground.
- FIG. 1 a schematic side view of a mobile excavator with different attachment versions of a bogie, with the number of the axle lines coupled to the travel unit being shown schematically;
- FIG. 2 a representation in which the different attachment versions are shown schematically from above, with some possible axle designs being shown for a single-axle bogie coupled to the travel unit;
- FIG. 3 other embodiment variants of a mobile excavator in accordance with the invention, with some axle designs for a two-axle bogie being coupled to the travel unit by way of example;
- FIG. 4 a schematic side view of a mobile excavator with different attachment versions of a bogie, with the number of the axle lines coupled to the revolving superstructure being shown schematically;
- FIG. 5 a representation in which the different attachment versions are shown schematically from above, with some possible axle designs for a single-axle bogie coupled to the revolving superstructure being shown;
- FIG. 6 other embodiment variants of a mobile excavator in accordance with the invention, with some axle designs for a two-axle bogie being coupled to the revolving superstructure by way of example; and
- FIG. 7 a further schematic side view of a mobile excavator with an alternative attachment version of a bogie.
- a mobile excavator 10 is shown in FIG. 1 .
- Two axle lines 14 and 16 are provided at the travel unit 12 of the mobile excavator 10 .
- FIGS. 1 a, b, c and d different designs of bogies or dollies 18 are shown which can here be coupled to the travel unit 12 by way of example.
- the type of the connection between the bogie 18 and the mobile excavator 10 is not shown in detail here.
- the bogie can generally be flanged on with torque stiffness. However, it can also be angled on via a biased spring unit. The bogie does not have to engage directly on the travel unit 12 . It can also be
