Underwriters Laboratories Inc., Research Triangle Park, NC, has contracted with ANCO for the delivery of a R5L 5-ft square 5,000-lb payload servo-hydraulic shake table for Bellcore/Telcordia GR-63-CORE (NEBS) seismic and office vibration qualification, and other earthquake qualification tests.

The dual horizontal and vertical tables, similar to the ANCO R4M 4-ft square seismic table delivered to Environmental Test Labs of Dallas, TX, allows for NEBS Zone 4 testing.

Test time and effort is reduced via a unique “pallet” feature of the table that allows quick transfer of the test item from either the vertical to the horizontal table frame, or from one horizontal axes to the second, or to an off-table preparation area.

A single 20-ton actuator is used to perform the vertical or horizontal testing.  The R5L table can also be configured to perform seismic tests simultaneously in both axes.
