1. Propulsion: A medical cart needs to be moved within a hospital or clinic, so sufficient propulsive force needs to be applied to move the cart. The pushing force should be strong enough to overcome friction and resistance, so that the cart can move smoothly.
2. Stability: A medical cart needs to be stable during movement to avoid swaying or tilting. Therefore, designers need to consider the structure of the bottom of the cart and the location of the center of gravity to ensure that the cart remains stable when moving.
3. Steering: Medical dollies need to be able to steer in tight spaces to accommodate different layouts within a hospital or clinic. Therefore, the design of the cart should consider the flexibility and ease of maneuverability of the steering mechanism.
4. Braking force: medical carts need to be able to stabilize the stop, especially in the case of moving suddenly stopped. Braking force requirements should be able to quickly stop a moving cart and keep it from sliding or backing up.
It is important to note that the external force requirements for a mobile dolly may vary depending on the medical device and the environment in which it is being used. Therefore, when specifically selecting a medical dolly, it is best to determine the appropriate external force requirements based on the actual situation and use needs.
