Stringing Block

A stringing block, also known as a pulley block or cable block, is a critical component used in power line construction and maintenance. It is designed to guide, support, and tension cables during the stringing process. Our MARSHINE Stringing Blocks are specifically engineered to handle the high tension and heavy loads associated with power transmission and distribution projects.

What Types of Stringing Blocks Does MARSHINE Offer?

MARSHINE provides a range of blocks tailored to different applications and load capacities:

Single Pulley Blocks: Simple and compact, these blocks are ideal for light-duty operations, such as guiding cables during initial installation.

Double Pulley Blocks: Equipped with two pulleys, these blocks are designed for medium-duty tasks, allowing for increased tension and load distribution.

Triple Pulley Blocks: High-capacity blocks with three pulleys, suitable for heavy-duty operations, such as stringing large-diameter conductors or bundle cables.

Swivel Blocks: Designed with swivel joints, these blocks allow for multi-directional movement, making them ideal for complex layouts and uneven terrain.
