NEW! Super reeve Connector Swivel Sockets (SCS-SW)

Our new Super reeve Connector Swivel Socket (SCS-SW) is the result of further development of our patented Super reeve Connector Socket (SCS), which has proven itself in the field during the past eight years. In this new design, we have added an integral swivel.

Our patented Super reeve Connector Socket (SCS) is a revolutionary evolution of the Fast Connector Socket (FCS). This socket line has the smallest connector diameter available in the market today, and still meets the respective EN standards. It has been designed to go through the smallest spaces in a crane reeving system. This unique patented design allows refitting by pouring in the field, saving valuable down time compared to swaging techniques. 


Ropeblock has a strong and global network of stocking distributors. This ensures end-users and OEM’s immediate availability to Ropeblock sockets.

Spelter socket loading mechanisms characterize themselves as very complex and was researched intensively by Ropeblock using strain gauge testing and Finite Element research. A true and full understanding of the non-linear behavior is required to pursue the engineering optimum. This optimum was completed in geometry with our market first anti-rotation and negative force nose and low notch factor design for improved fatigue service. The full range of Ropeblock sockets are type approved by DNV GL and LRS.

Our standard socket range is available in quenched and tempered cast steel with mechanical properties meeting today’s tough market requirements. All our sockets are suitable for usage in a sub-zero temperature environment. Materials meet or exceed an impact value of > 42 Joule / -20°C Charpy-V. The Ropeblock socket is marked with size, wire rope diameter and batch or serial number. All parts are fully traceable to their certificate by batch or serial number marked on each component.

Ropeblock sockets are subject to the most stringent surface and volumetric NDT procedures, excluding any risk for production flaws. These procedures are accepted by all third party authorities. Sockets can be proof loaded in accordance with the Ropeblock testing program, this implies testing up to 40% of the MBL of the socket.
In-house access to a vertical socket test bed, as well as a horizontal general purpose test bed is available to ensure fast reaction time. Custom designed testing tools have been developed to test all elements, including the basket.

All Wedge, Spelter and Fast and Super reeve Connector Sockets are finished with a Ropeblock-blue primer, or a hot dip galvanized finish.

Special requirements
Our engineers are ready to work on any special requirements you may have. Advanced 3D CAD and Finite Element Method (FEM) techniques decrease the time-to-market of new innovative socket designs. These designs include, but are not limited to, different materials (e.g. stainless steel), advanced features (e.g. swivel socket), aesthetic designs (e.g. for bridge work).
