In modern times, with the rise of the industrial revolution, more and more equipment needs to be moved, and heavy-duty casters are becoming more and more widely used around the world. Almost all walks of life are inseparable from heavy-duty casters. So what are the structural characteristics of heavy-duty casters? Let's introduce them in detail from seven aspects.
1. Installation height: refers to the vertical distance from the ground to the installation position of the equipment. The installation height of heavy-duty casters refers to the maximum vertical distance from the bottom plate of the heavy-duty casters to the edge of the wheels.
2. Bracket steering center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core.
3. Rotation radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. Appropriate spacing enables heavy-duty casters to turn 360 degrees. Whether the turning radius is reasonable or not directly affects the service life of heavy casters.
4. Driving load: The load-bearing capacity of heavy-duty casters when moving is also called dynamic load. The dynamic load of heavy-duty casters varies depending on the factory's testing methods and the materials of the wheels. The key lies in the structure and quality of the bracket. Resistant to shock and vibration.
5. Impact load: The instantaneous load-bearing capacity of heavy-duty casters when the equipment is impacted or vibrated by the load. Static load Static load Static load Static load: The weight that a heavy-duty caster can bear in a stationary state. The static load should generally be 5 to 6 times the operating load (dynamic load), and the static load should be at least 2 times the impact load.
6. Steering: Hard, narrow wheels are easier to turn than soft, wide wheels. The turning radius is an important parameter for wheel rotation. If the turning radius is too short, it will increase the difficulty of steering. If the turning radius is too large, it will cause the wheel to shake and shorten its life.
7. Driving flexibility: The factors that affect the driving flexibility of heavy-duty casters include the structure of the bracket and the selection of bracket steel, the size of the wheels, wheel types, bearings, etc. The larger the wheels, the better the driving flexibility. Narrow wheels save more effort than soft wheels with flat sides, but soft wheels save effort on uneven ground, but soft wheels can better protect equipment and absorb shocks on uneven ground.
