The invention relates to a mobile shovel loader,
on the front part of which a working shovel on a lift - and? lowerable shovel arm and a hydraulic J

Lischen kinematics device is actuated. In particular i and preferably the invention is applicable to an f

Articulated wheel loader intended.

It is known in such shovel loaders or wheel loaders to use an excavator as an adaptation part at the rear of the carrier I

to be attached to the vehicle. This has the disadvantage that the |

Excavator not from | due to poor visibility

Cab can be operated from, so that the driver is at |

every work process such as driving up or maneuvering \

to the excavator or the rear part of the vehicle must. Since the excavator is an adaptation part of the shovel i

loader must be operated is a quick change from }

I the operation of the shovel loader's working shovel |

on the excavator of great importance. In the previously known · ..

In addition, two people are required to attach the excavator to the rear, apart from the slow relocation possibility.

The invention has the object of providing a quick and convenient Umstei%-lung of the shovel to the excavator ψ

if possible by remote control hydraulically enable. This object is achieved by the invention in that the working shovel at the front end of the shovel arm or the kinematic device can be removed and one that can be raised, lowered and pivoted to the side Front excavator can be attached with a bucket or the like. So there is a choice namely either with the working shovel or with the |

Work front excavator. |

According to a particularly advantageous embodiment the invention of the swivel arm of the excavator or the working shovel of the loader either by means of a Quick-change carrier or the like. Be attached to the shovel arm or the kinematic device of the loader. the Movements of the excavator can be controlled by a remote control | device electrically from the driver's cab or from controlled outside the device.

In the arrangement of the front excavator according to the invention, the change from one to the other device in can be carried out by an operator in the shortest possible time. Another advantage of the arrangement of the front excavator on the Loading shovel arm means that the driver can not only operate and work with the excavator from the cab,

but he can also use the bucket kinematics to set the range, digging depth and working height far beyond the improve the previous possibility of the excavator. In a vehicle with articulated steering, the swivel range can of the excavator has been expanded by around 80 ° from the previous 180 ° to a total of 260 ° thanks to the articulated steering of the carrier device will. Remote control has other advantages.

The invention is illustrated schematically, for example, in the drawing.

Fig. 1 shows a side view of a shovel loader

an attached front excavator in several lifting positions, and

Fig. 2 shows the shovel loader according to FIG. 1 in plan view with several side pivot positions of the Front excavator.

The shovel loader chosen as an exemplary embodiment consists of a wheel loader 1 with a front part 1a and a rear part 1b, which parts are connected to one another by an articulation joint 8. Different bend angles of the two

■■ , j-,

Wheel loader parts 1a and 1b are shown in dashed lines in FIG Lines indicated.

On the front part 1a of the wheel loader 1 is a shovel arm 2 with a hydraulic kinematic device 2a around a rotary 5 axis 9 can be raised and lowered. At the front end of the S shovel arm 2 and the kinematic device 2a can by means of

ί a quick change carrier 3 or the like. one in the drawing

I working shovel not shown are attached.

j Instead of this working shovel, the invention

I 1 ο measured at the front end of the shovel arm 2 and the kinematics device 2a optionally by means of the quick-change carrier

^; a liftable and lowerable and laterally pivotable front excavator 4 can be attached with an excavator bucket 10, as can be seen from FIGS. 1 and 2 of the drawing. Instead of the Bag-1 5 tjerlöffeis, other adaptation parts such as hydraulic hold timers 6 or orange peel grabs 7 (see Fig. 1) can also be used on the excavator.

$ should be provided. The operator of the device can

} with the help of a remote control device 5 for difficult

t inspect the work on site, which incidentally as well

h 20 a control of the excavator movements from the driver's cab 11

; conveniently made possible without the operator having to get out.

In the case of dangerous demolition work, the operator can stay outside the danger area due to the remote control and work.

The excavator valve is controlled electrically via a proportional valve. This allows the operator to proportionally control the speed of movement of the excavator itself.

Overall, the economy of the device is significantly increased, and by the design according to the invention larger areas of application of the device are covered. In addition, the invention is not limited to the above embodiment described and illustrated in the drawing, but it also includes all corresponding Types of application. For example, the front excavator could also be used on a shovel loader without articulated steering or on a Loaders can be used with crawler tracks.
