EXTRACTION INSTALLATION FOR MINERAL EXTRACTION |
| 摘要 |
An extraction machine for an extraction installation is disclosed. The extraction installation may have a chain having a first chain strand section with a first end and a second chain strand section with a second end. The first and second chain ends may be connectable to the extraction machine for moving the extraction machine. The extraction machine may have a first chain mount configured to be connected to the first chain strand section. The extraction machine may also have a second chain mount configured to be connected to the second chain strand section. In addition, the extraction machine may have a first pre-tensioning device for building up a pre-tensioning force acting on the first chain mount such that a pulling force acts on the first chain strand section in the direction of the second chain mount. |
