Installation height: refers to the vertical distance from the ground to the installation position of the equipment. The installation height of the casters refers to the maximum vertical distance from the bottom plate of the casters to the edge of the wheels.
Support turning center distance: refers to the horizontal distance from the vertical line of the center rivet to the center of the wheel core.
Turning radius: refers to the horizontal distance from the vertical line of the center rivet to the outer edge of the tire. The proper spacing enables the casters to turn 360 degrees. The reasonable turning radius directly affects the service life of the casters.
Driving load: the bearing capacity of the casters when moving is also called dynamic load. The dynamic load of the casters varies according to the factory test methods and the wheel materials. The key is whether the structure and quality of the support can resist impact and vibration.
Impact load: the instantaneous bearing capacity of the casters when the equipment is impacted or vibrated by the load. Static load Static load Static load Static load: the weight that the casters can bear under static state. Generally, the static load shall be 5~6 times of the driving load (dynamic load), and the static load shall be at least 2 times of the impact load.
Steering: Hard, narrow wheels are easier to turn than soft, wide wheels. The turning radius is an important parameter of 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 lead to wheel shaking and shorten the life of the wheel.
Driving flexibility!
