The invention relates to a method for monitoring wear on crawler tracks in mobile machines, in which the chain is driven via a sprocket by a hydraulic motor via a mechanical transmission. The play between the teeth of the chain and the teeth of the drive is determined, for which purpose the path of the teeth during the starting movement is determined by a measurement of the angle of rotation at the drive.
The invention relates to a hydraulic excavator comprising a lower travelling unit, a superstructure rotatably mounted on the travelling unit, a boom (6) connected to the superstructure, a work tool at the distal end of the boom, hydraulic cylinders, and hydraulic components (5), such as connections, valves and hydraulic tubes and hoses, for moving the boom (6) and the work tool, wherein the hydraulic components (5) are combined to form a structural unit on a steel structure crossbeam (4) and can be detachably fastened on the boom (6) by means of said steel structure crossbeam (4).
A mounting arrangement for a tensioning device with a tensioning unit in a side carrier of a crawler of a tracked undercarriage in a large machine is disclosed. The tensioning unit is arranged in a side carrier compartment in the side carrier of the crawler, wherein a mounting opening is arranged in the side carrier on the outside thereof in an installation area of the tensioning unit for allowing removal of the tensioning unit, when installed, from the side carrier compartment through the mounting opening transversely to a track running direction.

The invention relates to a drive wheel and chain links for a crawler drive, with a crawler track revolving around the drive wheel, in which the upper strand - depending on the direction of revolution of the crawler track and the direction of rotation of the drive wheel - runs into or runs out of the drive wheel at a different angle and runs out or runs in as the lower strand, and wherein at least one cam is provided on the drive wheel together with at least one cam of the chain link of the crawler track, said cams being in engagement with one another, transmitting the torque and being radially raised or recessed in relation to at least one running track. The drive cams on the drive wheel and on the chain links are provided here with different drive contours or drive bodies with respect to the planes of symmetry for forwards travel and reverse travel and are thereby formed asymmetrically per se.
The invention relates to a crawler track for tracked vehicles, wherein the chain links are provided with articulated eyes facing one another, in which chain bolts connecting the chain links to one another are arranged. At the respective outer contour of the areas of the articulated eyes facing one another, a contour adaptation takes places on at least a partial circumference of the articulated eye, which on at least a partial area has a curvature, which is zero or positive (convex) in the viewing direction from the adjoining articulated eye end face to the center of the articulated eye.

The invention relates to a drive wheel for a track drive of a tracked vehicle, comprising a base body, which has at least one running track, and cams transmitting the torque from the drive wheel to the track, wherein drive cams, which are releasable independently from one another, are arranged on the base body for transmitting the torque.
The invention relates to a mounting arrangement for a tensioning unit in the lateral member of crawler-chain truck assemblies of tracked undercarriages in large machines, wherein the tensioning unit (12b) is arranged in a lateral member compartment (12a) in the lateral member (12) of the crawler-chain truck assembly and a mounting opening (13) is arranged in the lateral member (12) on the outer side thereof in the installation region of the tensioning unit (12b), via which mounting opening the tensioning unit (12b) in the installation position can be removed from the lateral member compartment (12a) transversely with respect to the crawler-chain running direction
