DESIGN NOTES

HAKI Stair Tower

ALL HAKI Systems have been designedto conform to current British &European standards. The loadingcriteria contained in this manual havebeen calculated according to currentEuropean standards.

Base Jacks

The stair tower is mounted on BaseJacks which are adjustable in height.This means the standards can alwaysbe adjusted to ensure that the beamsare horizontal.

Standards

Standards of 4.0m, 3.0m & 2.0m inlength are used. Shorter standardsmay be used as top standards.

Horizontals

The stair tower is built using 2.5 LedgerBeams, Single Tube Beams and 1.25mTransom Units with 1.5m betweenplatforms.

Anchorage

The stair tower must be anchored tothe structures at alternate levels (3mvertically) on both sides (inner andouter standards) using scaffold tubeand couplers.

Permissible Loads on Standards

When calculating the permissibleloads on standards the followingvalues apply, provided that all otherrequirements are fulfilled. Stair towerwith 1.5m stair flights 34kN perstandard.

ERECTION PROCEDURE

At front end to tower, locate entrancetransom over 2 base jacks. These need to beadjusted to estimated final height.

1 2

2a

Place Base Jacks onto sole pads, lay outLedger Beams, Single Tube Beams, TransomUnits and 4m Standards.

!

Note:To ensure the stairflight will locate ontoTransom, check minimum height with infillplatform.

1) Prior to starting erection, determineposition of tower.(minimum plan dimension 1.25m x 2.5m)

2) Ensure the ground is fully prepared toreceive the stair tower.

3) Minimum of 2 competent erectors.

4) Always start with the first flight on the left hand side.

5) The use of a 1.25m x 600mm erection platform.

6) ALWAYS ENSURE ALL LOCKINGCATCHES ARE ENGAGED

THIS MANUAL IS BASED ON THE FOLLOWING:-

Note:Ensure Base Jack handles are in line withthe Ledgers.

2b

Note:Should the first exit be required at 2m, then theerection procedure differs.

Build first lift, but replace Entrance Transom withTransom Unit in first set of pockets on the Standardand fit Entrance Step.
