ABSTRACT:
A height-adjustable work table has a support frame with at least one telescopic column having at least one support slidably displacable in the telescopic column. The work table has a table top and a weight-compensating device comprising at least one force reservoir and a pulling cable for adjusting the height of the support is provided. A force compensating device is connected to the weight-compensating device. The force reservoir has a first and a second end whereby the first end of the force reservoir is connected to the support frame and the second end is connected to the force compensating device. The weight-compensating device cooperates with the force compensating device such that for displacing the support the effective leverage of the force-compensating device is adjustable such that a counterforce generated by the weight-compensating device is at least partially compensated.
