Heavy-Duty Hoist

Hydraulic Decoking System

Ruhrpumpen provides specially designed hoists for decoking services. Our heavy-duty hoists can be provided with electric, hydraulic and pneumatic drives according to heavy-duty standards and RP's specifications. Pull force and pull speed are defined to actual requirements to provide a trouble-free operation in conjunction with other Delayed Coking components like the Coke Cutting Tool, the Drill Stem Drive and the Crosshead with Free Fall Arrestor.
