The rotational performance is excellent by the round pun through the sold stand.
Through the rise prevention device, the additional rise prevention device is not needed.
Compared the vertical rise force, it's suitable for the large and long bridge.
Pin&Roller Bearing As it's combined with the functions of the round roller and pin stand as a dynamic stand,
its rotational function is excellent. Due to the low friction count, the movement is
excellent. During the earthquake movement, both the movement restriction and rise
prevention device makes operators do not needthe bridge fall-off facility and rise force
prevention device. In addition, due to the wide load size, it's suitable for the
intermediate and large-sized bridge.
