Choosing the Right Sheave Block

One of the most important parts of a lift system consisting of a series of pulleys and wires or ropes is the sheave block. This component guides the wires or ropes in the system, helping to make the work of lifting heavy items easier.

The block and tackle system have been around for centuries and was one of the first tool systems invented to help humans move heavy loads. Believed to have been invented by Archimedes around 250 BC, the mechanical advantage this system provides allows us to move extremely heavy loads by less people than would otherwise be possible without it. Kennedy Wire Rope & Sling Company offers various types of sheave blocks to match your particular use and need. Each type of sheave blocks that we offer have different load capacities. We encourage you to reach out to us for a consultation on which would work best for your industrial, construction, or other application.

When assembling a system, it’s important to carefully consider the following factors when selecting a sheave block:

Load Capacity

First and foremost, you should consider how much weight your system will have to lift. A sheave block usually has a recommended weight limit that shouldn’t be exceeded if you want your system to work properly for a long period of time. Be sure you build your system around the largest load you will have to lift to ensure you don’t have to spend the time and effort upgrading too soon in the future. In addition, the diameter of the rope you use will also have an impact on the amount of weight the system can lift.

Block Type

There are several types of sheave blocks to choose from. Before settling on one block in particular, it’s important to look into the benefits of each type to ensure you purchase the right sheave block. You should select one that will not only work best for your system, but also for the type and weight of the loads you will lift.
