7 Inch Universal Cable Roller Stringing Block with 10kN Rated Load Φ178×76mm Sheave and Adjustable Crossarm Caliper for Transmission Line Installation

The CSB 7" universal cable roller and stringing block is engineered for transmission line installation, cable pulling, and power line construction. With a 10kN rated load and Φ178*76mm sheave, this cable pulling block delivers stable cable guiding support during overhead line installation.

The adjustable crossarm caliper enables mounting on crossarms with widths from 99-175mm and heights from 95-159mm. Its lightweight 4.3kg design facilitates easy transport, installation, and operation on site.

During transmission line installation and cable pulling operations, contractors frequently encounter:

• Cable friction during pulling operations
• Difficult cable guiding on crossarms
• Unstable roller positioning during overhead line work
• Low efficiency when installing temporary cable rollers
• Heavy tools increasing labor intensity at height

These operational challenges primarily result from:

• Improper roller size causing cable wear
• Unstable mounting structure on crossarms
• Insufficient load capacity for field pulling work
• Heavy pulley blocks increasing installation difficulty
• Lack of adjustable tools for different crossarm sizes

The CSB 7" universal cable roller addresses these challenges through:

• 10kN rated load for stable cable pulling support
• Φ178*76mm sheave for smooth cable guiding
• Single sheave structure for simple and efficient operation
• Adjustable crossarm caliper for 99-175mm crossarm width
• Lightweight 4.3kg design for easy field installation
• Suitable for transmission line and power line installation work

During pulling or stringing operations, the cable passes through the rotating sheave. The Φ178*76mm sheave guides the cable smoothly and reduces friction during installation.

The adjustable caliper securely fixes the roller onto the crossarm, maintaining stability during operation. This design makes the tool ideal for overhead line installation where temporary cable guiding is required.

The Φ178*76mm sheave provides smooth cable guiding and reduces pulling friction during line installation.

The 10kN rated load capacity makes the cable roller suitable for common cable pulling and transmission line installation work.

The caliper accommodates crossarm widths from 99-175mm and heights from 95-159mm, ensuring adaptability to various site conditions.

With a block weight of 4.3kg and caliper weight of 1.6kg, the tool is easy to transport and install during overhead line construction.

The roller is specifically designed for transmission line installation, cable pulling, and overhead power line work.

This 7" universal cable roller and stringing block is widely used for:

• Transmission line installation
• Power line construction
• Cable pulling operation
• Overhead line installation
• Crossarm cable guiding
• Utility construction work
• Temporary cable support during stringing

For light and medium cable pulling work, the 10kN rated load is suitable. For heavier conductor pulling, choose a higher load stringing block.

For crossarm installation, choose this model with adjustable caliper. For ground cable laying, select ground cable roller type. For corner pulling, choose corner cable roller type.

For small and medium cables, the Φ178*76mm sheave is suitable. For larger cables or conductors, choose larger diameter stringing blocks.

For overhead line work, choose lightweight and portable structure. For long-distance pulling, use multiple cable rollers to reduce friction and protect the cable.
