Crosshead with Free Fall Arrestor

Hydraulic Decoking Systems

Ruhrpumpen's standard crosshead design is an efficient component of a cutting system for heavy-duty tasks in refineries.
Our proprietary Free-Fall Arrestor retrofit designs reduce the safety risk of the brakes of the crosshead and can usually be installed without interruption to existing decoker operations.
