Rear outrigger seal kit for Demag AC 615

The 77816573 seal kit serves as a maintenance set for the rear outrigger cylinder of Demag cranes. Its primary function is to maintain the hydraulic integrity of the outrigger system by preventing fluid leakage and ensuring the cylinder maintains the pressure required for stabilization during lifting operations. The kit contains a collection of seals, O-rings, and backup rings configured to restore the sealing performance of the cylinder assembly.

This component is compatible with the Demag AC 615 crane model. It is designed to fit the specific dimensions and requirements of the rear outrigger system, providing the necessary seals to address leakage issues within the hydraulic circuit. Proper installation of these components helps maintain the operational stability of the crane by ensuring the outrigger cylinders function correctly under load.

Outrigger seal kits generally include a variety of sealing elements such as piston seals, rod seals, and rod wipers. These components are installed within the hydraulic cylinder to separate high-pressure fluid from the external environment and to prevent contaminants from entering the hydraulic system. By replacing worn seals, operators can prevent pressure loss and maintain the intended movement and load-bearing capacity of the outrigger system.
