Stressing Chairs - RSXSCTK
|
 |
The stressing Chair utilizes a threaded keeper plate to adjust to an applicable distance for 2-part and 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.
|
|
|
|
|
|
|
|
|
|
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.

Post-Grout Tube
|
 |
Williams will provide post-grout tubes for anchors bonded in weak rock or soil upon request. The Williams supplied flexible post-grout tube has a bursting strength of 1000 psi. The post-grout tube length and valve placement are adjustable and can be specified at the time of order. There is no field assembly of the post grout tube, other than attaching it to the anchor as it is being installed down the drill hole.

| The heavy duty, high volume Colloidal Grout Plant is favored for precision post-tension grouting. The unit features a high speed shear mixer that thoroughly wets each particle and discharges the mixed material into a 13 cubic foot capacity agitating holding tank. A direct coupled progressing cavity pump delivers slurries at a rate of up to 20 gpm and pressures of up to 261 psi. The unit easily mixes and pumps slurries of Portland cement, fly ash, bentonite, and lime flour. All controls are conveniently located on the operator platform for easy one-man control. |
