Abstract (en)
[origin: WO2006081925A1] The invention relates to a treatment bed, comprising an arrangement of two mechanically-parallel lifting motors in the height-adjusting lift mechanism. According to the invention, tension in the lifting mechanism may be avoided and both motors equally loaded by provision of a symmetrical circuit, which measures the supply currents of the lifting motors. When a difference is generated, the related current is temporarily interrupted several times in the sense that brings the related operation parameters of the currents together.
