Protected cargo: The number one reason to use shock-absorbing casters is to reduce the vibration transferred to the contents of the cart.
Reduced noise: Carts can make a lot of noise when traveling over rough surfaces. Spring-loaded casters reduce this by smoothing out the ride.
Decreased risk of overload: The shock absorption feature equalizes the load among four or more casters, reducing the chance of overload and the uncontrollable twisting of the cart.
Increased ease of use: Dollies and carts with spring-loaded casters are easier to roll over cracked flooring, uneven surfaces, thresholds, and other obstructions.
Reduced risk of damage to the floor: Shock absorbency reduces wear and tear on the flooring beneath the casters.
