Where equipment requires the use of a spring type mount for a high degree of isolation under normal operating conditions, but with the facility to restrain the equipment from excessive motion in any direction due to displacement inputs imparted by the foundation through earthquake activity.
An integrated, stand-alone six direction restrained twin spring mount with cup located springs and internal adjustment.
Restraint capacity is given as a maximum static force. The following can be applied simultaneously in one lateral direction and vertically up or down: Vertical: 34kN Lateral: 20kN
At maximum restraint loads, the displacement from normal operating position is approximately 10mm.
Hot dipped galvanized steel housing, oil-resistant high-frequency spring base isolation cup. All other components including spring are zinc plated.
XVIHS-2 Mounts are designed with spring horizontal to vertical stiffness ratios between 0.7 and 0.9 at rated loads; ratio of spring diameter to loaded height minimum 0.8; and a rated maximum static operating deflection 2/3 deflection to solid.
