World-class Load Distributive Type Anchor Other Product of SW-SMART JACK | SAMWOO

SAMWOO GEOTECH Co., Ltd. has been endeavoring to be the leading company in the ground anchor industry for over 27 years since its establishment in 1993.

SAMWOO SW-SMART JACK

The smart Jack was developed to uniformly distribute the stressing force to individual strands of each anchor body. Load distributive type anchors uniformly distribute the stressing load to the grout body and soil along the theoretical length of the bond zone. The spacing of the anchor bodies in this manner results in various un-bonded strand lengths and corresponding elongations. The conventional center-hole jack simultaneously stresses the steel strands which, if used for this application, will result in higher forces applied to upper anchor bodies and less to lower bodies as positioned in the borehole. Applying jacking force to the anchor bodies in this manner is not efficient and may result in overstressing of steel strands and anchor failure. The Smart Jack was developed and designed with multiple cylinders so each strand is stressed independently allowing the operator to inspect and manage elongations and jacking force of individual strands. This ensures that the jacking force is evenly distributed to individual strands based on their un-bonded lengths and that no strand is excessively loaded. earth anchor system manufacturer

Features and merits of SW-SMART JACK

ü  Stressing wedges are located at the front end of the unit which results in reduced anchor tail length requirements.

ü  Position of stressing wedges in-unit minimizes bending of anchor tails during installation of the jack prior to applying alignment load. grouted rock anchors manufacturer

ü  Lock-off systems uniformly minimize wedge slip.

ü  Allows individual stressing of anchor bodies as required.

ü  Jack weight is relatively light as compared to conventional jack. Therefore, it is easier to install and transport units.

ü  Jack was developed on its own by SAMWOO and has been successfully used at numerous anchor installation projects in Korea and abroad.
