Manual Turned Winch for Overhead Power Transmission Distribution Lines Stringing

A Manual Turned Winch for Overhead power transmission Distribution Lines Stringing is a portable, hand-operated mechanical device used to pull, lift, and tension conductors or ropes during the installation and maintenance of overhead power lines. It provides controlled, incremental pulling force without the need for electrical or hydraulic power, making it ideal for fieldwork in remote or challenging locations.

Key Features and Specifications:

• Capacity Range: Typically available with load capacities from 0.5 tons up to 3 tons (approximately 5 kN to 30 kN), suitable for various stringing tasks.

• Rope Diameter and Length: Common rope diameters range from 6.3 mm to 12.5 mm, with rope lengths around 40 meters for effective reach during stringing operations.

• Lever Force and Velocity Ratio: The lever force required to operate the winch ranges from 120 to 180 Newtons, with velocity ratios (mechanical advantage) varying from about 4.3:1 up to 29:1 depending on the model, allowing efficient manual operation with manageable effort.

• Construction: Made with high-strength alloy steel components and treated for durability and corrosion resistance, ensuring reliability in outdoor environments.

• Operation: The winch uses a ratchet and clamp mechanism to grip the wire rope securely. The operator moves the handle back and forth to incrementally pull the conductor or load, with the ability to release or reset the clamp as needed.

• Portability: Weighing between approximately 14 kg to 44 kg depending on capacity, these winches are designed to be portable and easy to handle on-site.

• 

Application in Overhead line stringing:

• Manual winches are used to pull conductors through OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks mounted on transmission towers and to tension conductors to the correct sag.

• They are essential tools for controlled conductor installation, especially in areas where powered winches are impractical.

• The precise manual control helps avoid conductor damage and ensures safety during stringing operations.
