Pull Test for Scaffold Ties
Timber frame scaffolds needn’t be hard. If your structure can take the imposed horizontal load, tie in every other standard, every other lift, make your lifts 2.0m and the scaffold will conform to TG20 08. A sample of the anchors/ties shall be tested to a load of at least 1.5 times the tensile load. A minimum of 3 anchors/ties shall be tested and at least 5% (1 in 20) of the total job. TG4 04

We have erected 2 scaffold lifts around the base of the building . After the scaffold is erected to this stage we stop. The timber frame erectors now erect their panels, ring beam, and floor. When the panels and ring beam and floor are in place we can remove the inside handrail as the floor acts as fall protection. Before any other lifts of scaffold are added we must tie into the timber frame at the intervals recommended. |
Screw the ties into the timber frame,every other standard ,every other lift.Or according to a design you may have |
Next we test a percentage of the ties ( 1 in 20 or 5 %)with the pull tester to make sure that the structure will take the imposed loading, in this case 1.5 x the imposed load is tested. |
When the tie has been tested we can then tie into the scaffold not forgtetting to link the tie from standard to standard. The scaffold can now be raised another 2 lifts.

 Ladder tower being erected, the ladders protect the ladder hole; this tower also acts as a buttress to further support the scaffolding.
|
 The scaffold is now complete. A ladder tower has been added so has a 15kn loading tower, the loading tower has been designed by our engineers .The scaffold is now ready to be handed over as the ties are checked, the loading bay is designed and the scaffold conforms to TG20 08 & TG4 04
|
Prestige scaffolding offers a complete pull testing service at competitive rates. Remember you can’t hand a scaffold using mechanical ties unless they have been tested TG4 04.
