Vertical Strand Anchor Uncoiler
The Williams Vertical Uncoiler can be utilized to install up to a 61 strand anchor. The uncoiler is a safe and cost effective strand anchor installation solution while minimizing damage to the corrosion protection sleeves. Contact a Williams representative for a monthly rental rate.
Stressing Heads – RSXSHPK
The stressing head applies a temporary stressing force to the tendon and maintains the load until the lock-off load is transferred to the anchor head. The stressing head assembly should be used in all applications to insure uniform strand tension. Anti-seize compound is available to assist stressing head release.
Stressing Chairs – RSXSCP
The stressing Chair utilizes a keeper plate to adjust to an applicable distance for 3-part wedge sets. The stressing chair assembly can be used for proof testing of the strand anchor assembly, incremental lock-off loading, or typical installation loading.
