Rear outrigger seal kit for Demag AC 615

The 77816673 seal kit is designed for the maintenance of rear outrigger cylinders on Demag cranes. These seals are used to restore the hydraulic integrity of the cylinder assembly, which is responsible for the extension, retraction, and load-bearing stability of the crane outriggers. By replacing worn seals, the kit helps prevent internal and external hydraulic fluid leakage, ensuring the cylinders maintain the required pressure to hold the machine in a stable position during lifting operations.

This component is compatible with the Demag AC 615 model. It contains the specific seals required for the rear outrigger assembly as identified by the manufacturer. The kit addresses the common wear points within the cylinder that can lead to pressure loss and inconsistent stabilizer performance over time.

Hydraulic seal kits serve to contain fluid within a cylinder while preventing contaminants from entering the hydraulic system. They are critical for maintaining the pressure necessary for heavy machinery to operate its stabilization components safely and effectively.
