1. A system for supporting a patient, comprising:
a platform of a surgical table configured to support at least a portion of the patient; and
a base positioned beneath the platform and configured to support the platform, the base configured to contact a ground surface and the platform movable vertically relative to the base, the base comprising a load-sensing lift mechanism comprising:
a support foot,
a caster wheel,
a motor configured to raise and lower the support foot,
a vertical shaft connecting the support foot to the motor,
a load cell support beam mounted to the vertical shaft, and
a load cell beam connected to the support foot, the load cell beam being cantilevered relative to the vertical shaft and comprising a sensor for measuring applied vertical forces,
wherein the motor is configured to raise the support foot to a retracted position with the caster wheel contacting the ground surface, and the motor is configured to lower the support foot to an extended position to prevent the caster wheel from contacting the ground surface.
