ABSTRACT:
A column drawing table where the weight is equalized by a gas spring. This gas spring is supported in an elastic receptacle between the column and the pedestal foot, and the column is guided in a hollow pedestal so as to be movable along its length. It can be stopped at an arbitrary position by a fixing brake. A fall safety device, operative completely independently of the fixing brake, prevents the column from unintentionally sinking if the gas pressure in the gas spring should decline or if the fixing brake should be released.
