Product Overview

The SM-417 Grooved Closed Spelter Socket is a wire rope termination component designed to connect wire rope with compatible lifting, rigging, structural and industrial equipment.

Its closed-type socket configuration provides an enclosed connection structure compared with open-type spelter sockets. The grooved internal design accommodates the wire rope termination, while the socket body provides the connection interface for the complete wire rope assembly.

The SM-417 can be supplied in different sizes to match specific wire rope diameters and application requirements.

It is suitable for applications where a properly engineered and permanently or semi-permanently terminated wire rope connection is required.

Important: The rated capacity of a finished wire rope assembly depends on the socket size, wire rope construction, socketing method, connection hardware and applicable requirements. The socket model alone should not be treated as a universal WLL rating.

Product Features

1. SM-417 Closed-Type Design

The SM-417 uses a closed spelter socket configuration, providing an enclosed connection point for compatible wire rope assemblies.

This configuration can be selected when the application requires a closed connection rather than an open socket arrangement.

2. Grooved Internal Structure

The grooved socket body is designed to accommodate the wire rope during the socketing process.

Correct positioning of the wire rope inside the socket is essential for the performance of the finished termination.

3. Steel Construction

The socket body is manufactured from steel suitable for industrial rigging and wire rope termination applications.

The exact steel grade and mechanical properties can be specified according to the applicable product requirements.

4. Multiple Sizes

Different SM-417 sizes can be supplied according to wire rope diameter.

Key selection parameters include:

• Wire rope diameter
• Socket dimensions
• Connection dimensions
• Overall length
• Socket opening

• Required capacity

5. Industrial Wire Rope Termination

The socket can be incorporated into engineered wire rope assemblies for:

• Crane equipment
• Lifting systems
• Industrial machinery
• Construction equipment
• Structural wire rope systems
• General rigging applications

6. Surface Treatment Options

Depending on the working environment, the socket can be supplied with suitable surface treatment options.

Possible finishes include:

• Plain steel

Product Advantages

Applications

Crane Equipment

SM-417 sockets can be incorporated into properly engineered crane wire rope assemblies.

The complete assembly should be selected and rated according to the crane manufacturer's requirements and applicable lifting standards.

Industrial Lifting Systems

The socket may be used for wire rope termination in industrial lifting equipment and material-handling systems.

Construction Equipment

Applications may include:

• Construction machinery
• Steel structures
• Hoisting equipment
• Supporting wire rope systems
• Heavy equipment

Industrial Rigging

The closed spelter socket can be used in engineered rigging assemblies where the wire rope requires a secure termination and connection to compatible hardware.

Structural Wire Rope Systems

For selected structural applications, the socket can provide the termination interface between wire rope and supporting components.

How a Closed Spelter Socket Works

A spelter socket forms a termination by securing the prepared wire rope inside the socket body using an approved socketing material.

The general process is:

Wire Rope Preparation → Wire Rope Splaying → Socket Insertion → Positioning → Spelter/Resin Filling → Curing → Inspection

The exact process should follow the approved procedure for the specific wire rope, socket and socketing material.

SM-417 Installation Process

Step 1: Confirm the Wire Rope

Check:

• Rope diameter
• Rope construction
• Rope grade
• Core type
• Application requirements

The wire rope must be compatible with the selected SM-417 socket.

Step 2: Prepare the Rope End

The wire rope end is prepared according to the approved socketing procedure.

Depending on the wire rope construction, the strands may need to be opened and properly splayed.

Step 3: Insert the Wire Rope

Position the prepared wire rope inside the SM-417 socket.

Correct alignment is important for the final termination.

Step 4: Apply Socketing Material

An approved spelter or resin material is introduced into the socket according to the specified procedure.

Step 5: Allow Curing

The socketing material must fully cure before the wire rope assembly is subjected to its intended load.

Step 6: Inspect the Assembly

Check:

• Socket body
• Rope alignment
• Socketing material
• Connection area
• Visible cracks
• Deformation
• Corrosion
• Overall assembly condition

How to Choose an SM-417 Spelter Socket

1. Match the Wire Rope Diameter

The socket must be selected according to the actual wire rope diameter.

Using an incorrectly sized socket may affect the quality of the finished termination.

2. Check Wire Rope Construction

The rope construction should be confirmed before ordering.

Relevant information may include:

• 6×19
• 6×37
• Rotation-resistant rope
• Compacted wire rope
• Galvanized wire rope
• Stainless steel wire rope

Not every wire rope construction should automatically be terminated using the same socketing method.

3. Check Connection Dimensions

The closed socket must be compatible with the mating component.

Check:

• Connection opening
• Pin diameter
• Connection width
• Socket length
• Overall dimensions

4. Check Load Requirements

For lifting applications, the complete wire rope assembly should be evaluated.

Consider:

• Wire rope breaking strength
• Socket capacity
• Termination efficiency
• Connection hardware
• Load direction
• Dynamic loading
• Safety factor
• Applicable regulations

SM-417 Closed Socket vs G416 Open Socket

The correct socket depends on the required connection arrangement rather than simply choosing one model based on size.

Manufacturing Process

A typical SM-417 production process includes:

Steel Material → Forming → Machining → Grooving → Connection Processing → Surface Treatment → Inspection → Packaging

1. Raw Material Preparation

Specified steel material is prepared according to the required technical specification.
