Definitions
- the present invention relates to a construction equipment, and more particularly, to a construction equipment in which excavation and loading functions can be performed by one equipment.
- a construction equipment such as an excavator and a loader is used to excavate, convey, and load earth and sand in the construction site.
- the excavator is to excavate or load earth and sand or rock during earthwork.
- the loader is to load excavated earth and sand, aggregate, crushed rock into a conveyer.
- the excavator and the loader work differently from each other in view of kinematics. In other words, since the excavator acts using pulling power while the loader acts using pushing power, they have different structures from each other. Therefore, both the excavator and the loader are used for excavation and conveyance of earth and sand in the construction site.
- the weight of the construction equipment greatly increases and also the size of the main body that supports the excavator, the loader, and the forklift truck relatively increases. For these reasons, a problem essentially occurs with respect to unnecessary increase of the volume of the construction equipment or its balance. Problems occur in that the respective equipments such as the excavator, the loader, and the forklift truck do not work satisfactorily because they have different structures in view of kinematics.
- the present invention is directed to a construction equipment having excavation and loading functions, which substantially obviates one or more problems due to limitations and disadvantages of the related art.
- An object of the present invention is to provide a construction equipment in which excavation and loading functions can be performed by one equipment without any degradation of performance to remarkably reduce the expenses of the equipment and its size.
