Hydraulic Operated ROV Shackles
Options
DEVELOPED BASED ON THE REQUEST FOR LARGER SIZED SHACKLES.
Imenco has responded to industry demand by designing a shackle which can be utilized off shore for heavy lifts. Both the lifting pin and the locking mechanism are hydraulically operated. In case of hydraulic failure, the smart design of the release mechanism for the hydraulic cylinders enables the spring to be used as a backup.
