Double Sliding Eradi Quake System

DSEQS is developed from EQS, OMEQS, EQS Plus and FDB, this has designed for sliding in upper and lower part independently, this system is able to provide large movement (about two times) simultaneously, even if its size is smaller than EQS.
As a results, with this optimized size of device, it also has a advantage to fulfill design structural requirements which is to keep minimum offset distance from edge of substructure.
