A cable pulley is a very simple application that we use in mechanical systems. The cables are attached to these systems to carry and transfer loads. Also, the pulley applications are fixed to the other bodies and objects to carry the load that the cable transfers to these systems.

In general, they have a groove that cable fits inside it. And cable can move freely over this rotating groove. And the groove is attached to a shaft. The shaft is generally made from stainless steel to carry the load coming from the cable.

Applications that We Use Cable Pulley Systems

They are very general mechanical load-carrying systems. And the applications are various in different fields. Here you can find different kinds of applications.

  • GYMs: The use of cable pulley applications are very common in GYM in general. Different systems consist of these different sizes of pulleys. To pull and carry the weights, you use cable pulley applications in general.
  • Industry: To carry heavy weights and products, the use of these systems is very common in general.
  • Transportation: On ski lift systems and cable car applications, the use of the cable pulley systems. They are very important to transport different weights.
  • Agriculture: Also dealing with heavy things is also very common in agricultural applications. Carrying the farming equipment hays generally made with cable pulley applications.
  • Construction: If you are dealing with construction, the use of cable pulley applications is very common in general.

So, in different kinds of systems, we see the use of cable pulley applications.

How to Choose a Proper System?

There are different kinds of parameters that you need to consider about these systems. And choosing the best system will be very easy for you.

  • Load capacity: This is the first parameter that comes to mind. Because the pulley application must withstand the maximum load that you will carry.
  • Size: There are different sizes of pulley systems available in the market. You need to choose the best application that fits the requirements of your system.
  • Safety: Safety is also very important. Some applications have guards to prevent accidents in general. And they prevent reaching the moving parts in these systems.
  • Environment: In which kind of environment you are planning the use these systems? If you will use these systems in a corrosive environment, you can use them in different kinds of environments.
  • Budget: You need to define the budget so that you can spend the maximum money on these things. So, they are very different systems that you can deal with. You do not need to pay extra money for systems that have excessive features that you do not need.

While choosing these applications, do not forget to consider these important things.

Maintenance Tips

Cable pulley systems are carrying very high amounts of force. And damage to these systems can cause very big problems such as accidents. So, we give some maintenance tips below.

  • Check for wear and tear: Also we need to check for wear and tear on the pulley. Be sure that the system does not have damage.
  • Lubrication: You need to lubricate the pulleys on regular basis. The systems that have low lubrication will probe to be worn. So, it is very important to make the proper lubrication in general.
  • Cleaning: Do not forget to clean the cable pulley system that you have. Because the filth and wear can cause such problems.
  • Professional maintenance: Also if you are using these systems that you carry very heavy objects, the professional maintenance schedule is very important. You can do it by calling the distributor of the pulley system or the manufacturer to make the required professional inspections.

Symptoms of Bad Cable Pulley

And we want to give some tips about the general sounds that you can hear if the cable pulley system goes bad. So, you can understand that you need to take action.

  • Difficulty in moving: If movements with these applications are harder than before, this means you may have a damaged and worn system.
  • Misalignment: The loose bolts and nuts and also corrosion can cause the misalignment of the cable pulley system.
  • Increased wear and tear: Check for the parts of the system if the wear and tear are increased. This is a very big problem and you need to take care of this situation.
  • Noises: In cable pulley systems, the most common symptom that you will see is the noises coming from the cable pulley system. The squeaking sounds will be the most common symptom in general.


So these are the general points that we can state about the cable pulley applications. We explained the maintenance tips, problems, symptoms, and solutions of them. Also if you are thinking about buying one of these systems, we explained the important parameters that you need to consider.
