Compact excavator
The mini excavator is a construction machine and place on small construction sites in the area of earthworks or the garden and landscaping use. The device is characterized by its low operating weight and small dimensions.
The operation of the machine is similar to a hydraulic excavator. Facilities include a small dozer blade, tracked undercarriage and a number of attachments such grave vessels, hydraulic hammer or auger.
Components
The mini excavators essentially consists of five components:
Parameters
Mini excavators are available in various design and performance variants, the power ranges from machines with 3 to 17 kW. The device then has an operating weight of 0.3 up to 3.2 t. Crucial for the ability to help is also the width, so are possible dimensions between 0.7 and 1.5 m. There is a maximum speed from 1.7 to 5 km / h.
Technology and equipment
Equipped with a hydraulic drive mini excavator consists of a tracked chassis with rubber tracks. In this way, the device can rapidly change the direction and produces only low ground pressure. The small attached to the undercarriage dozer blade is used for light grading, and can serve as a support during the dredging process. In order to improve the mobility of the machine is depending on the version on the boom approach of a center pivot, so that the boom without rotation of the superstructure can be swiveled. The applications are due to the different types of attachments very versatile.
Use
The devices are used due to their size and weight in tight spaces and can be quickly transported to the truck bed or a car trailer. The mini excavator is used in restoration work of buildings and facilities as well as used in gardening and landscaping. You can also perform minor earthworks and replaced in this case, the tedious and expensive manual labor. The areas to be expanded by various attachments.
Manufacturer
A variety of manufacturers engaged in the development and manufacture of mini excavators. This has led to a broad mass of models and sizes. Despite their similarity to the conventional hydraulic excavators, all components must be re-dimensioned. Especially the right to achieve the smallest possible size devices, requires a high performance design. Among the manufacturers of mini excavators include, for example:
- Airman
- Ammann Yanmar
- Bobcat
- Boki
- Cams
- Case CE
- Caterpillar
- Doosan (formerly Daewoo )
- Eurocomach
- Foton ( excavator )
- Mecalac
- Messersi
- New Holland
- Pel-Job
- Takeuchi
- Terex / Schaeff
- Volvo Construction Equipment
- Wacker Neuson
- XCMG
Security
- In Germany an annual U -VV verification (according to the guidelines of the professional associations) is mandatory for mini excavators.
- A certificate of competence (ticket ) for guiding Mini excavators in Germany is a prerequisite for the proper use of all power-driven (mini excavators ) according to the guidelines of the professional associations.
