Casters made of polyurethane wheels provide better shock absorption effects for Manual Hydraulic Stackers due to the inherent properties of polyurethane as a wheel material. Here's why polyurethane wheels are effective at shock absorption:
1. Elasticity: Polyurethane is a highly elastic material. It can deform and then quickly return to its original shape when subjected to a load or impact. This elasticity allows polyurethane wheels to effectively absorb shocks by deforming and dissipating the impact energy.This property helps in reducing vibrations and jolts when the stacker moves over uneven surfaces or encounters obstacles.
2. Damping Characteristics: Polyurethane has excellent damping characteristics. It can dissipate vibrations by converting kinetic energy (movement) into thermal energy (heat) as it deforms and rebounds. This reduces the transmission of shocks to the stacker and the load.
3.Polyurethane wheels distribute the load more evenly over their contact surface with the floor. This feature helps in minimizing point-loading and local impacts, as the load is spread out more effectively.

4. Quiet Operation: Polyurethane wheels are known for their quiet operation. They absorb sound energy generated by friction and impacts, resulting in a quieter and less disruptive workplace.
5. Resistant to Abrasion: Polyurethane is a durable material that resists wear and abrasion, making it suitable for demanding industrial environments. The longevity of polyurethane wheels ensures consistent shock absorption over time.
6. Non-Marking: Polyurethane wheels are non-marking, meaning they do not leave scuffs or marks on the floor, which is essential for maintaining a clean and presentable workspace.
7. Chemical Resistance: Polyurethane is resistant to many chemicals, oils, and solvents. This resistance ensures that the shock-absorbing properties of the wheels are not compromised by exposure to various industrial substances.
8. Versatility: Polyurethane wheels are versatile and can be used on a variety of floor surfaces, including concrete, tile, and wood.
While polyurethane wheels are effective at shock absorption, it's important to note that their performance may also depend on the design and construction of the caster, the wheel diameter, and the specific application. When selecting a Manual Hydraulic Stacker, consider the type of polyurethane wheels and other caster features to ensure they are well-suited for your material handling needs and the operating environment. Proper maintenance and care of polyurethane wheels are essential to maximize their shock absorption benefits and prolong their service life.
