what type of suspension do forklifts have

Forklifts are an essential part of many warehouses and manufacturing plants, making work easier and more efficient. They have been around for more than a century and have undergone many changes and improvements to become what they are today. One aspect of forklift design that is often overlooked but plays a significant role in their performance and safety is their suspension system. In this article, we will delve deeper into the types of suspension forklifts use and their advantages and disadvantages.

Leaf Spring Suspension

One of the most common types of suspension found in forklifts is the leaf spring suspension. Leaf springs consist of multiple arched layers of steel that are held together with bolts or clamps. The spring absorbs shock and distributes weight evenly, providing a smooth ride. Leaf springs are known for their durability and can handle heavy loads. They are also less expensive than other suspension systems and can be easily modified or repaired. However, leaf springs can be noisy and uncomfortable, especially when driving on bumpy roads.

Coil Spring Suspension

Another type of suspension used in forklifts is the coil spring suspension. Coil springs are made of round wire and compress and rebound when pressure is put on them. They provide a smoother ride than leaf springs and are more comfortable for the driver. Coil springs are also quieter and easier to adjust to different loads. However, they are more expensive than leaf springs and are not as durable.

Gas Shock Absorber Suspension

Gas shock absorber suspension is a type of suspension that uses a hydraulic shock absorber and a gas-filled chamber to provide a smooth ride. The hydraulic fluid compresses when the forklift hits a bump, and the gas in the chamber absorbs the force, reducing vibrations. Gas shock absorber suspension is known for its excellent shock-absorption and quick recovery time. It also handles uneven terrain better than other suspension systems. However, it is more complex and expensive than other suspension types and requires regular maintenance.

Hydraulic Suspension

Hydraulic suspension is a relatively new type of suspension used in forklifts. It uses hydraulic cylinders to adjust the height and stiffness of the forklift's suspension based on the weight of the load and the terrain the forklift is driving on. Hydraulic suspension provides a smoother ride than other suspension types and can handle uneven terrain better. It is also more efficient when it comes to energy consumption. However, it is still a new technology and is expensive. It also requires specialized maintenance and repairs.

Conclusion

In conclusion, forklifts use different types of suspension systems to provide a smooth ride, increase safety, and improve handling. Each suspension type has its advantages and disadvantages, and choosing the right one depends on the type of work the forklift will be carrying out and the budget available. Understanding the different types of suspension systems can help with the decision-making process, ensuring that the forklift chosen is the right one for the job.
