OPERATION
•
Ensure castors are and securely braked once the tower is in position.
•
Use the height adjustment mechanism on the castors to ensure the tower base is level.
•
Ensure outriggers are fitted to increase the base width of the tower if the platform is over 4 metres in height.
•
Outriggers must rest firmly on the ground and be fitted to any side of the tower that is not within 300mm of a secure
support surface, ie. a wall
•
Climb up the ladder and through hatch lid to gain access to the platform maintaining three points of contact at all
times while on the ladder.
•
Ensure the total load does not exceed 225kgs.
•
The tower must only be used on a firm surface that is free of obstructions.
STEP 7:
If the platforms are supported by either of the top three transoms on the upper frame lift, guardrail frames must be
installed.
Guardrail frames fit onto the lower frame spigots as per step 6 and are locked with spring clips.
Attach one only angle brace hook immediately adjacent to one of the lower braces and the upper end to the second
transom on the guardrail frame as shown.
Attach a guardrail and midrail on the two top transoms of the guardrail frames on both sides of the tower as shown.
A toeboard set must be attached to the platform level on all towers over 2mH or where there is a significant risk of tools
or materials being dislodged from the platform.
Note A:
The procedure above is also completed where a guardrail frame set is attached to the top of the base frame
set.
Note B:
before any tower over 2mH is operated; the working level must be fully decked with platforms. There must be
a guardrail attached between 0.9m - 1.1m above the platform level along with midrails on each side of the tower.
STEP 6:
Follow these directions where the tower is to be erected higher than a single lift:
Place the next two Frames on Spigots inserted into the top of the base frames.
Attach Spring Clips through Frame Standards into the groove in the spigot to lock them together.
Attach two more diagonal braces to the tower. One end of the braces attach to the same transoms as the lower
braces.
Attach the other end of the braces to the relevant transom on the second frame lift as shown.
Note;
the two braces in this assembly must also be set at opposing angles to each other.
Install a ledger guardrail on each frame side at least 0.9m above
the platforms for temporary protection while the tower is being
erected.
Raise the platforms to the desired working
height or to the top transoms on the
second frame lift.
If Tower is set up
over two levels high
then Outriggers must
be attached to the
Standards as shown.

There are two outriggers supplied with tower
configurations over 2 lifts high as standard. If the
tower is to be operated more than 300mm away
from a fixed vertical support surface two more
outriggers must be attached so that there is one on
each corner of the tower.
Outriggers must be positioned to increase the base
dimensions as much as much as practicable with a
minimum height to width ratio of 3:1.
