Art of Forklift Tires: Types of Forklift Tires
Without the right tire design, forklifts may struggle to establish a firm grip on the ground, increasing the risk of accidents and diminishing overall operational efficiency. Forklift tires come in various types, each suited to specific work environments and forklifts.
Pneumatic Forklift Tires
Pneumatic forklift tires are a great option for both indoor and outdoor jobs, depending on your needs. Compared to cushion tires, pneumatic tires have thicker tread, which provides stability and durability on uneven surfaces.
Air Pneumatic Tires
Air pneumatic tires are filled with air, similar to car tires. They have thick and durable treads and are best suited for outdoor environments. Pneumatic tires are wider and longer than cushion tires, making them better equipped to absorb uneven ground and handle rough terrain.
Use air pneumatic tires for jobs requiring a transition from indoor to outdoor heavy equipment use, multi-use and versatile jobs on gravel, small rocks, or other uneven outdoor sites, heavy-load and high-capacity projects, and uses requiring a sturdy, shock-absorbing ride.
Air pneumatic tires are a great choice for jobs that involve transitioning from indoor to outdoor heavy equipment use, as well as for multi-use and versatile jobs on small rocks, gravel, or other uneven outdoor sites. They are also ideal for heavy-load and high-capacity projects and uses that require a sturdy, shock-absorbing ride.
Solid Pneumatic Tires
Solid pneumatic tires, on the other hand, are made from solid rubber and are not easily punctured by jobsite debris like metal or nails. Their powerful durability makes them a great choice for outdoor environments like recycling centers or lumber yards, where rough terrain requires sturdy tires. While they are usually more expensive than air pneumatic tires, their long lifespan and maximized productivity in tough job sites make them a worthwhile investment.
Use solid pneumatic tires for airport loading sites, lumberyards, railyards, agricultural job sites, oil, gas, and mining sites, and other rough terrain applications.
Cushion Forklift Tires
Cushion tires are a great option for indoor surfaces, especially in warehouses. These tires are made from solid rubber molded onto a steel band, which makes them durable and long-lasting.
Compared to pneumatic tires, cushion tires are more cost-effective and sustainable, requiring less manufacturing material and labor. They are ideal for compact warehouse areas where small tires and low-ground clearance are needed. Cushion tire forklifts work well in small spaces and narrow aisles. They also work best for indoor warehouses and other indoor job sites with smooth flooring. If you have a smaller forklift frame, cushion tires are a great choice.
Specialty Forklift Tires
Non-Marking Forklift Tires
Non-marking forklift tires prevent black marks on warehouse floors. You can choose from different types of pneumatic, solid, and cushion tires that can be customized to be non-marking. Traditional tires can also be converted to non-marking tires, and they are suitable for various indoor and outdoor warehouse settings.
Non-marking options are designed without carbon black, which makes them the perfect solution for sensitive applications such as food and paper production, as they prevent cross-contamination with carbon dust. Non-marking tires are recommended for food storage and packaging operations and other job sites where operators must avoid cross-contamination.
Polyurethane Forklift Tires
Polyurethane tires are designed to be lightweight and easy to install, and they are resistant to splitting even when used in light warehouse applications. Compared to rubber tires, they can last up to twice as long, especially when used for indoor warehouse projects and stock-picking jobs.
For best results, use polyurethane tires for the following purposes: lightweight warehouse jobs, electric forklifts that reduce rolling resistance, longer-lasting wear and tear, and warehouses that require chemical resistance.
Science Behind Tread Design
We should understand how forklift tires work and how different factors can affect their grip and performance. Knowing this information can help you make informed decisions about which tires to choose and ensure that they work safely and efficiently in different situations.
The Physics of Traction
Traction, the ability of a tire to grip the road surface, is fundamentally governed by the principles of friction and adhesion. These two factors play a crucial role in the interaction between the tire and the ground.
- Friction: Friction is the resistance encountered when two objects move against each other. In the context of forklift tires, it’s the force that opposes the sliding of the tire on the ground. Tires are designed to maximize friction to enhance traction.
- Adhesion: Adhesion is the molecular attraction between the tire’s rubber and the road surface. It results from the chemical interaction between the two materials. Tire manufacturers optimize rubber compounds to improve adhesion, which increases the tire’s grip.
The Influence of Weight Distribution
Traction is also influenced by the way the weight is distributed on the forklift. The load’s weight must be evenly distributed across the tires to maximize traction. An uneven load distribution can reduce traction on one side, potentially leading to skidding or loss of control.
How Tire Materials Impact Traction
Rubber Compounds
The rubber compound used in tire manufacturing plays a significant role in traction. Manufacturers formulate specific rubber compounds to enhance grip while maintaining durability and wear resistance. Softer rubber compounds offer better traction but may wear faster, while harder compounds offer greater longevity but may sacrifice some grip.
Heat Resistance
Tires generate heat during operation, particularly during high-speed and heavy-load activities. Tires must withstand this heat to maintain their performance and traction. Heat-resistant tire compounds are essential for durability and maintaining grip under high-stress conditions.
The Role of Tire Size and Shape in Traction
Tire size and shape can have a significant impact on traction.
- Size: Larger tires often offer more traction due to a larger contact patch with the ground. This is advantageous when moving heavy loads.
- Shape: The design and shape of the tire affect its contact area and distribution of load. Specialized tire shapes are engineered for specific applications to optimize traction and stability.
Choosing the Right Forklift Tires
Selecting the right forklift tires is a crucial decision that significantly impacts the efficiency, safety, and overall performance of your material handling operations.
Nature of Operations
Choose the right forklift tires based on the number of shifts and trips your forklifts make, the speed and length of the run of your operations, and load frequency.
Load Capacity
The maximum weight your forklift will carry is another consideration. Ensure that the tires you choose can handle the specific load capacity required for your applications. Underestimating load capacity can lead to tire wear and operational inefficiencies while overestimating can compromise stability and safety.
Indoor vs. Outdoor Use
The environment in which your forklift operates plays a significant role in tire selection. If you work in rough outdoor terrains, pneumatic forklift tires are the best option. However, if you mostly operate indoors, cushion tires can be a good choice. If you handle food or medicine, non-marking tires can be a great option as they don’t leave any marks on the floor and do not shed any harmful compounds.
Operational Speed
The speed at which your forklift operates significantly affects tire choice. High-speed operations create greater forces and generate more heat. Tires designed for high-speed applications have features to provide better stability and heat resistance.
Surface Conditions
The type of surface your forklift operates on is critical. Consider whether the surface is smooth, rough, wet, or uneven. Different surfaces demand varying levels of traction and durability, so select tires that can effectively handle your specific working conditions.
Materials Handled
Fragile or high-value materials may require tires that reduce shock and vibrations to prevent damage. On the other hand, heavy, bulky items demand tires with exceptional traction and load-bearing capacity.
Maneuverability
Some applications involve tight turns and precision maneuvers. Tires that provide superior handling and maneuverability may be essential in these cases.
Weather Conditions
If your material handling takes place in areas with extreme weather conditions, consider tires that can withstand temperature fluctuations, including those designed for enhanced cold weather performance.
Technical Requirements
Not all tires will work for every forklift, so make sure to follow the manufacturer’s instructions for the ideal tire type. This is especially important for safety reasons. When choosing your tires, consider the capacity and class of your forklifts as well. Following these guidelines will ensure the safe and efficient operation of your forklift.
