Description

Flowserve

Flowserve Crosshead Free Fall Arrestor System is an advanced solution designed to enhance safety and efficiency in Hydraulic Decoking Systems. The Free Fall Arrestor System ensures that the cutting assembly in decoking operations is safely suspended and can be quickly stopped in case of rope tension failure, preventing damage to personnel and equipment. Flowserve’s technology is engineered for robust, high-performance operations in demanding industrial environments like petroleum refining and heavy oil upgrading.

Crosshead Free Fall Arrestor for Hydraulic Decoking Systems

The Flowserve Crosshead Free Fall Arrestor unit plays a critical role in guiding and centering the rotary joint-drill stem-cutting tool assembly within the coke drum. The Crosshead is engineered to safely absorb all torque loads typically sustained during cutting operations. Designed for Hydraulic Decoking Systems, this solution enhances operational safety and efficiency in decoking applications.

Hydraulic Decoking Systems Crosshead (Free Fall Arrestor) Features and Benefits

The Flowserve Crosshead Free Fall Arrestor System is available in two distinct designs:

Shoe-type Crosshead: Features two rectangular-shaped shoes that slide within the structure’s beams for smooth operation.
Wheeled-type Crosshead: Incorporates four wheel blocks with spring-loaded guides in two planes that move along a track attached to the structure’s beams.

The Free Fall Arrestor (FFA) is built into the crosshead, providing an added layer of protection by preventing the cutting assembly from falling in the event of suspension failure. This safety mechanism does not require electric or pneumatic connections for activation, ensuring seamless operation even under challenging conditions.

Key safety and operational benefits include:

Prevents cutting assembly equipment from falling and potentially damaging the cutting deck, offering superior protection for both personnel and equipment in case of steel wire rope failure.
Safeguards ancillary equipment from damage caused by falling machinery.
FFA automatically disengages once the required rope tension is restored, ensuring safe and effective operation.
