2. STEP-BY-STEP CONSTRUCTION In this presentation You will learn how to safely erect and dismantle a tower scaffold Consider the health and safety issues that arise When you are ready click the mouse once to continue

3. STEP-BY-STEP CONSTRUCTION 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 Click once to continue

4. STEP-BY-STEP CONSTRUCTION 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. Before you start... Click once to continue

6. STEP-BY-STEP CONSTRUCTION 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: Click once to continue 1 2 3 4 5 6 7

7. STEP-BY-STEP CONSTRUCTION Safety Feature Before 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 Click once to continue

8. STEP-BY-STEP CONSTRUCTION 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 Step 3 Click to view Health and Safety information Click once to continue

9. STEP-BY-STEP CONSTRUCTION Step 4 Question… Why do we use outriggers and why is it very important that the outrigger is set to an angle of 45 …. ? o Answer Click your mouse to find out Outrigger Fix and adjust the first outrigger to the base unit

10. STEP-BY-STEP CONSTRUCTION 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 metres Click once to continue

11. STEP-BY-STEP CONSTRUCTION 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? Click your mouse to find out H&S

12. STEP-BY-STEP CONSTRUCTION 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

13. STEP-BY-STEP CONSTRUCTION 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!! IMPORTANT Click once to continue H&S

14. STEP-BY-STEP CONSTRUCTION Raise and fix the first side extension Step 9 Step 10 Locate the spring clips in the holes to secure the extensions Health and Safety information Raise and fix the second side extension IMPORTANT Click once to continue Safety clip secured Safety clip applied Safety clip holes

15. STEP-BY-STEP CONSTRUCTION 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 Click once to continue

16. STEP-BY-STEP CONSTRUCTION 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

18. STEP-BY-STEP CONSTRUCTION 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 Click here to return
