摘要： A device for tensioning chains on crawler-type or tracked vehicles, in particular the chains of hydraulic excavators, comprises a first cylinder arranged in an area of the chassis for the tracked vehicle, and operatively connected via a piston rod to a guide wheel to tension the chain. A second cylinder forms a spring cylinder and is operatively connected to the first cylinder. The second cylinder concentrically encloses the first cylinder to form a double cylinder and each cylinder is provided with a separate hydraulic connection. At startup of the tracked vehicle, the hydraulic connections of the double cylinder are admitted with a specifiable pre-tensioning pressure. The spring cylinder can be moved with maximum spring travel to its end position because of its larger cross-sectional surface, and the tensioning cylinder pre-tensions the chain with a force that corresponds to the pre-tensioning pressure.

摘要： The retaining unit (1) has a bulk material collecting area formed by side walls (2) and a rear part (3). A bulk material retaining area (5) is formed with tooth units (4), where a protective cap (8) is arranged in an area of the side walls. The protective cap is fixed in its position through a protection unit (12) that is arranged in an outer side of the tooth units. The protective cap is connected with the side walls in a detachable manner through plugging. Grooves are provided in two longitudinal side pieces of a guiding area of the cap.
