Cable-pulling sheaves are a vital tool for anyone installing wires and conduits. Sheaves provide an easy way to manage, guide, and protect cables during installation, helping to ensure that the job is done correctly and efficiently. This blog post will discuss why cable-pulling sheaves are essential and how they can help with wire and conduit installation.

The Purpose of Cable Pulling Sheaves

Pulling sheaves are an essential tool for the installation of wire and conduit. This equipment reduces the force to pull electrical cables through a line length. In addition to providing more efficient cable-pulling, cable-pulling sheaves also reduce the risk of damaging the wires and make the process less time-consuming. They are usually attached to the end of the conduit. The cable is then placed in the sheave’s wheel and looped through the wheel a few times. As the wheel is rotated, it helps guide the line into the conduit and prevents it from snagging or tangling. Cable-pulling sheaves can come in various sizes depending on the job. Multiple sheaves may be used for larger jobs to ensure enough force is applied to pull the cable through the conduit. 

The Different Types of Cable Pulling Sheaves

Various cable-pulling sheaves are available on the market, each designed for a different application. When choosing the suitable sheave for your project, it’s essential to consider the type of cable or wire that needs to be pulled and the size and type of conduit. 

Rope or Chain: If you need to pull thick cables or multiple wires at once, you’ll want to use a rope or chain sheave. This type of sheave has a large diameter, which allows it to accommodate a more significant load and gives you more control over the pulling action. The ropes and chains also provide more friction, which helps prevent slipping during the pulling process.

Self-Locking: A self-locking cable-pulling sheaves can be used with cables with a smaller diameter than a rope or chain sheave. This type of sheave has a ratcheting mechanism that locks the line into place when pulling, providing added stability and safety during installation.

Belt Drive: Sheaves are usually used for long-distance pulls and heavier loads. They provide more control and flexibility than rope or chain sheaves and are typically less expensive. 

In the end

Choosing the suitable Pulling Sheaves for your project will depend on the size and type of cable you’re pulling and the environment in which it’s being installed. With the suitable sheave, you can save time and money while ensuring your wiring job is safe and secure.
