A surgical operating table has a cover (37) resiliently supported on a base assembly (3) and microswitches (39) that detect displacement of the cover (37) to prevent lowering of the patient support platform (1). The base assembly (3) has a castor plate (31) and a base plate (30) which is lowered to brake movement of the table over the floor. A pneumatic tube (35) around the base plate (30) senses the presence of an object under the plate (30) and causes the plate (30) to be raised. A tilt switch (5) in a leaf of the platform (1) prevents angular displacement of the platform (1) when its angle exceeds a safe limit. |
