Vibrations of heavy equipment, such as textile machinery, are isolated, that is prevented from entering into the supporting floor, by inserting a vibration isolating device between each equipment frame member forming a machine foot and the floor. The device includes a hydraulic damper and up to three sets of springs, preferably sets of concentrically arranged helical springs. The springs are mounted between upper and lower spring mounting elements. The spacing between these upper and lower mounting elements is adjustable by a threaded bolt for adapting the load bearing capacity of each set of springs to the respective machine foot load. Thus, individual springs in a set or an entire spring set may be withdrawn from a load bearing function for providing each machine foot, for example of a weaving machine, with the individually required vibration insulation at each machine foot.
