The Benefits of Using Cast Iron Elevator Counterweigh
Density
High density (about 7.4 gr/cm3) is one of the most important features of cast iron counterweights which fulfills the necessity of a high amount of weight. Compared to other materials such as cement with galvanized or plastic covering, a decreased number of cast iron counterweights can provide the needed weight in a relatively smaller space than other materials. This is an important point for elevator counterweights, which are expected to be heavy enough to counterbalance the weight of the elevator cabin but also need to fit into the elevator shaft.
Durability
If you are concerned about the quality of materials which leads to using counterweights with an extended life, and you need a strong and durable material that is resistant to wear and corrosion, and also, if you’re preoccupied with the maintenance costs of elevator equipment then, cast iron material is a suitable choice to be able to tolerate a constant strain and stress during the elevator operation.
Noise Reduction
In spite of the increasing amount of population in apartment residential and the increasing amount of traffic, cast iron counterweights paradoxically can bring peace and help to decrease the amount of noise and vibration generated by the elevator system. This is due to the density of the cast iron which helps to stabilize the elevator cabin and prevents it from sudden shaking or unsmooth moving as it goes up and down the shaft.
Environment Friendly
Besides the recent organizational demands and the increasing intention of investors on environment-saving projects, cast iron is an environment-friendly material because it’s a recyclable material through possessing the remelting and reusing features at the end of its life cycle. So, don’t hesitate to take part in the environment healing process.
Costs
At first glance, it may seem that cast iron counterweights are more expensive than the same good made of different materials but if you look at that from the experience angle, you will know that is a relatively inexpensive material that can help to reduce expenses due to the corrosion and the need to change the counterweights, installation, etc. This is an important point to be considered by elevator manufacturers and building owners who need to fulfill the important factors of safety, efficiency, and reduced future costs while designing and installing elevator systems.
Machinability
Although manufacturing companies in the field of casting bear some difficulties in the production process of cast iron equipment, cast iron is a material that is easily shaped and machined which makes it to be known as a popular choice for elevator counterweights. This capability allows manufacturers to produce customized sizes of counterweights that are precisely designed to fit the specific requirements of a particular elevator system. The important point and main concern for customers is that counterweights should have a smooth surface to be able to put them in a counterweight frame without troubles caused by unsmooth surfaces and carelessness in the casting process.
Thermal stability
Moving up and down the elevator shaft will cause the counterweights to be exposed to a wide range of temperatures which may result in deformation or warping of counterweights. In this regard, cast iron possesses the feature of thermal stability and prevents extra expenses due to the needed changes in counterweights.
Fire Resistance
Being fire resistance is an important factor for the materials used in a system that produces some amount of heat. Cast iron counterweight located in the elevator shaft is a fire-resistant material, which can help to prevent or slow the spread of fires in buildings.
Aesthetics
Physically, cast iron counterweights have a good appearance that can add to the overall aesthetic of a building’s elevator system especially in elevator systems made of glass. Because, in some cases, the counterweight frame is visible to passengers, so it’s important that it looks good and fits in with the overall design of the elevator system.
Conclusion
Overall, cast iron elevator counterweights provide a reliable, durable, and cost-effective solution for balancing the weight of elevator cabs. As mentioned in this article, it has some benefits such as high density, noise reduction, thermal stability, environmentally friendly, fire resistance, machinability, etc. KHOSRAVI Elevator Counterweights company can provide all these benefits besides a good price and it is also capable of producing customer-desired sizes counterweights with a high quality.
