The tower scaffold demonstrated here is for a single storey tower set against a wall.

A free-standing scaffold will be erected in the same way but will require four outriggers and additional cross braces and guard rails to close the open sides

In all cases if toe boards are supplied these should be fitted

Before you start it is important that you ensure you have all the component parts of the scaffold you will be building, and that you are correctly kitted out with safety equipment.

Scaffolding components

1. One collapsible base unit

2. One ladder

3. Two outriggers

7. Two side extensions

6. One platform

5. One short guard rail

4. One long cross brace

For a single level scaffold you will need:

Safety FeatureBefore we start it is important to understand the safety feature used to secure the scaffolding components together

Components fit together using a sprung end that snaps over the rung

To release the component the sprung lug must be pushed back

Position the base unit adjacent to the structure

Step 1

Ease the unit apart and grasp the hinged cross brace

Step 2

Gently push the cross brace upwards until it locks in position

Question…

Why do we use outriggers and why is it very important that the outrigger is set to an angle of 45 …. ?

AnswerClick your mouse to find out

Outrigger

Fix and adjust the first outrigger to the base unit


Answer

Outriggers are used to stabilise the scaffold

45 degrees is the best angle to do this

Using outriggers also allows you to increase the overall height of the scaffold up to a maximum of three times the base width

Example

If the distance between the outstretched outriggers is 3 metres, the maximum permissible height will be...

3x3= 9 metresClick once to continue


Fix and adjust the second outrigger to the base unit

Step 5

Ensure that the wheel brakes are all ‘on’ and the unit cannot freely move

Step 6

Fix the ladder to the top rung of one end of the base unit

Step 7

Question:

Why must the ladder be raised off of the ground?

H&SH&S


When moving a portable scaffold over uneven and obstructed ground, a ladder resting on the ground will be a

hazard as it will impede movement and be liable to catch on obstructions

Click once to continue


Fit the platform to the top of the base unit

Step 8

Ensure that the trap door is over the top of the ladder

Dismantling the scaffold just to correct this can take a lot of time…and that costs you money!!

H&SH&S


Raise and fix the first side extension

Step 9

Step 10

Locate the spring clips in the holes to secure the extensions

Fix a long cross brace between the top of one side and the bottom of the other

Step 11

Finally attach a short guard rail across the top of the two sides. This must be on the side of the scaffold AWAY from the wall

These two braces are very important as they help to stabilise the scaffold and act as a safety rail.

Step 12



You have now learned how to safely erect a mobile tower scaffold.

Dismantling is the reverse of this process.

As always care should be taken to ensure your safety. As it is taken down the various pieces should be safely stacked to avoid damage or

injury

IMPORTANT FINAL SAFETY POINT

A TOWER SCAFFOLD SHOULD NEVER BE MOVED WHILE SOMEONE IS ON IT

Health and Safety Information

It is very important to note that from this point erecting a tower scaffold is ideally a

two person job.

One should climb onto the platform and receive the parts handed up by the other.

Extreme care should be taken until the guard rail is fitted, by the person on the

platform
