The dimensions are equivalent to a standard D-type shackle of the same capacities, the pins and the opening width being the same, as are the Pad-eye dimensions, for example the 12Te standard shackle is a perfect match to our 12Te ROV operated shackle.
On client request hydraulic versions of the above standard ROV shackle range can be produced. This can be operated on ground level - thus off ering signifi cant safety advantages and eliminating the need for working at height.

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.
