Whilst our recommended method of assembly to fully comply with the Work

at Height Regulations 2005, is by using Advanced Guardrails (PlusGard™), a

secondary method has also been approved and endorsed by both PASMA

and the HSE. This method is known as the 3T method (Through The Trap).

NARROW WIDTH TOWERS

Narrow width towers are assembled following the same steps as explained

for span towers, except that all platforms are trapdoor platforms.

THE BASE SECTION

Fit two legs and castors (or base

plates) to one 2 rung span frame (see

illustration) and two legs and castors to

one 2 rung ladder frame. Turn the height

adjustment collar on each leg until

approximately 100mm from the lower

end. Insert each leg until the collar is in

contact with the frame’s tubing.

Set each castor brake on by moving the

brake lever fully down.

Attach two horizontals to the upright of each frame,above the rst

rung and square the two frames to each other.

Note It may be advantageous to place a platform at low level to

assist in “squaring” tower.

With the aid of a spirit level, you should now make any necessary

adjustments to level the tower by turning the adjustment collars.

Attach two temporary horizontal

braces to 2nd rung of frame.

Add one 2m (4Rung) frame and one

2m ladder frame on top of base (1m)

frames.

Assembly Procedure 1450 Tower - 3T

Attach two diagonal braces to

the bottom rung of each base

frame, with braces being placed

at least 50mm (one tube width)

from outer edge. Then attach the

other end of both braces to the

bottom rung on the opposing 2m

frame.

Attach two more diagonal braces (in accordance with brace pattern)

from 1st rung to 3rd rung of upper frame.

Remove temporary horizontal braces.

The base is complete
