The present invention provides an elevating bed capable of detecting braking performance. The elevating bed comprises an elevating assembly, a driving motor connected to the elevating assembly and driving the elevating assembly to move, a brake device connected to the driving motor and a control module connected to the driving motor and controlling the driving motor to rotate, and connected to the brake device and controlling the brake device to be enabled or disabled； when the control module disables the brake device, the control module controls the driving motor to drive the elevating assembly to move for a first movement distance and calculates a first torque value of the driving motor； when the control module enables the brake device, the control module controls the driving motor to drive the elevating assembly to move for a second movement distance and calculates a second torque value of the driving motor, the control module determining whether the brake device is normal or abnormal according to a relationship between the first torque value and the second torque value.
