Why don’t presses “walk” on isolators?
A. Presses don’t walk on properly selected free-standing isolators due to friction between the isolator and the foundation. To keep a machine from walking, the static deflection (compression) of the isolator under load must be greater than any dynamic unloading of the isolator caused by the operation of the machine. Properly selected and applied isolators always carry load, so the friction of the elastomer on the floor is usually sufficient to overcome any horizontal forces that cause a machine to walk.
