Sockets
Closed Wedge Socket
This technical datasheet outlines the CWS series of closed wedge sockets, designed for wire rope diameters between 18mm and 86mm. It provides MBL data from 44 to 689 UStons and lists the full dimensional layout (A through WD) for permanent yet quickly detachable end terminations.
Engineered for Ultimate Structural termination: High-Performance Closed Wedge Sockets
The Closed Wedge Socket (CWS) is a heavy-duty wire rope termination solution designed for high-capacity lifting and structural rigging. Manufactured from quenched and tempered cast steel, these sockets feature a streamlined, closed-end bow design that ensures maximum load transfer and snag-resistant performance in demanding industrial and maritime environments.
Maximum Strength & Material Integrity
- Premium Casting: Manufactured from high-grade quenched and tempered cast steel to provide superior durability and structural resilience under extreme tension.
- Extreme Load Capacities: Standard models offer a Minimum Breaking Load (MBL) ranging from 44 UStons up to 689 UStons.
- Certified Quality: All sockets are supplied with an EN 10204-2.1 declaration of conformity and an EN 10204-3.1 material certificate.
- Robust Corrosion Protection: Features a standard finish of blue primer coating and hot-dipped galvanizing for long-term field endurance.
Precision Engineering & Field Versatility
- Broad Wire Compatibility: Optimized to accommodate wire rope diameters from 3/4″ up to 3 3/8″.
- Compact Closed Design: The snag-free bow geometry provides a secure, permanent connection point ideal for mobile cranes, crawler cranes, and bridge stay systems.
- Controlled Manufacturing Tolerances: Ensures a ±5% tolerance for the bow opening (K) and bow thickness (C) for reliable integration with rigging hardware.
- Field-Efficient Adjustment: The wedge-style termination allows for rapid wire rope installation and field adjustment without requiring specialized speltering tools.
Closed Wedge Socket Technical Specifications
Below is a selection of technical specifications for the CWS series. Please contact our technical team for full dimensional details (A, B, C, TA, K, WH, WB, WD) and MBL verification based on your specific wire rope requirements.
⚠ Safety Warning: Always adhere to the Minimum Breaking Load (MBL) and ensure that the wire rope termination is conducted by qualified personnel. Surface finishes like hot-dip galvanizing or paint may slightly add to the overall thickness and fork distance; always verify site fit-up. Refer to the comprehensive safety documentation on pages 136-145 for full maintenance and installation procedures.
