Seismic Spring Isolator Type XVIHS-2

Heavy steel metal
Sound insulation cup
Height adjustment screws and nuts
One adjustable central vertical brake screw

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.

FEATURES Heavy duty stable steel spring Acoustically isolating location cup Internal leveling bolts Single adjustable central vertical restraint bolt Replaceable shock absorbing rubber snubbers

RESTRAINT CAPACITY Restraint capacity is given as a maximum static force. The following can be applied simultaneously in one later-al direction and vertically up or down: Vertical: 34kN Lateral: 20kN At maximum restraint loads, the displacement from normal operating position is approximately 10mm.

CONSTRUCTION Hot dipped galvanized steel housing, oil-resistant high-frequency spring base isolation cup. All other components including spring are zinc plated.

DESIGN 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.
