Lock-up Device (LUD)

Max. lock-up force8000kN

Product Description

The Lock-up Device (LUD) is able to provide counter force to its two ends and is applied when displacement is caused by temperature or wind. When braking forces or earthquake loads exceed a certain limit, counter-force applied by the LUD will increase along with this force and lock the two ends to limit their relative movement in order to protect structures. The device can transfer seismic energy effectively with great damping properties.
