Model ERS2010

Share this on social media:

Newport has introduced the Earthquake Restraint System, the Model ERS2010, designed to restrict the motion of pneumatically-isolated optical table tops during seismic activity.

The new earthquake restraint system is certified and in compliance with the 2009 International Building Code (IBC) and the 2010 California Building Code (CBC). A minimum of three restraints is required to prevent possible tipping of a table during or after an earthquake and, once installed, the system does not affect optical table performance.

Each restraint is rated for seismic forces generated by a maximum of 2,000 lbs (907 kg) of combined table and payload weight. A set of four restraints can withstand a maximum of 8,000 lbs (3,632 kg). Available in several standard heights, including 16-in. (406 mm), 19.5-in. (495 mm), 22-in. (559 mm), 23.5-in. (597 mm) or 28-in. (711 mm); custom heights and configurations are also available.

Each ERS2010 earthquake restraint is designed to be secured into a concrete floor at least 6-in. thick using eight Hilti anchor bolts. Seismic loads are distributed into the optical table bottom skin by eight socket head cap screws. The necessary hardware (not included with the restraints) is also available from Newport and can be ordered separately.
