Abstract
A protective arrangement is described for a piston rod of an excavator hydraulic cylinder is arranged between a vehicle frame and a scraper blade to serve as a working cylinder for lifting and lowering. For protecting the exposed piston rod, a shell-type protective sleeve is supported by way of a stationary slide ring while resting on the latter, and encloses the piston rod from above in a protective manner during the working operation.
