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

Design
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. Ropeblock OSS, CSS and SBS sockets are type approved by DNV and LRS.

Material
Our standard socket range is available in quenched and tempered cast steel with mechanical properties meeting today’s tough market requirements. The Short Bow range is also made of quenched and tempered cast steel, with a different chemical composition and with extremely high mechanical properties to achieve an unmatched weight to MBL ratio. 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.

Proof testing individual sockets
Sockets can be individually proof tested on request. The default proof load value is 40% of the catalogue MBL for spelter sockets and 30% for wedge sockets. Higher values until 50% will require special consideration.
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.

Finish
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).
