[rnJ]HAKrGeneralHAKIStair Tower is made from pre-fabricated components. The stair toweris built using standards, and ledger beams.Other stair tower components include stairflights, landings, handrail and guardrails.The stair tower can be built as a separateconstruction or integrated into other scaffol-ding or staging. All components are of galva-nised steel.

GENERALNOTES
HAKIStairTowerAll HAKISystems have been designed toconform to current Britishand EuropeanStandards. The loading criteria contained inthis manual have been calculated accordingto current BritishStandards.
BaseJacksThe stair tower is mounted on Base Jacks
which are adjustable in height. This meansthe standards can always be adjusted toensure that the beams are horizontal.
StandardsStandards of 3m and 2m in length are usedwherever possible. Shorter standards may beused as top standards.
BeamsThe stair tower is built using 1.605m and3.0m ledger beams, with 2.0m, 1.5m or1.Ombetween the platforms depending onwhich stair flight is used.
AnchorageThe stair tower must be anchored to the struc-tures at each platform levelon both sides(inner and outer standards) using scaffoldtube and couplers - see Page 15.

The stair tower must be anchored to the struc-
tures at each platform level on both ends(inner and outer standards) using scaffold
tube and couplers.
Stair flight is positioned vertically and located into pockets of lower landing (11A & 11B). Flightis then lowered onto landing above (11 C) and pushed along (11 D) until top of stair flight is fullylocated into pockets of upper landing (11 E).Note. At this stage check top and bottom of stair is fully engaged into both landing pockets.Stairflights should be erected for a clockwise ascent.

Using tube & couplers, the tower should betied to the structure below each lift position(except first lift) through both inside & outsidestandards.

Access PointsItisonly possible to have a side access point (3.05m) in a 2.0m lift.Access to/from end of tower (1.655m) is not restricted, but 1.605m ledger Beammay have to be raised to create sufficientheadroom when access liftis less than 2.0m.
For dismantling the Stair Tower, the reverse of the above squence should be followed.
