For general surgery, a 250 kg capacity is often sufficient, but for bariatric centers, a table with a minimum of 350 kg is recommended. Always ensure that the weight is evenly distributed on the tabletop to maintain stability.

How does the battery backup system work on an electric hydraulic operating table?

The battery backup system on an electric hydraulic operating table is designed to provide uninterrupted operation during a power outage. The table is equipped with a rechargeable battery, typically a sealed lead-acid or lithium-ion type, that is automatically charged when the table is plugged into a power source. In the event of a mains power failure, the battery instantly takes over, allowing all table functions to continue normally. The battery can usually power the table for a full surgical procedure, typically 2 to 4 hours, depending on usage. Some models have a battery indicator light on the control panel to show the charge level. It is important to test the battery system regularly, such as during monthly maintenance, to ensure it is holding a charge. If the battery is depleted, the table may still be operated using a manual override, such as a hand crank, which is included with most models. This redundancy ensures that surgery can continue safely even in emergencies.
