Mobile scaffold towers

Mobile scaffold towers may be constructed of basic scaffold components or made from light alloy tube. The tower is built up by slotting the sections together until the required height is reached. A scaffold tower is shown in Fig. 1.22. 

Describe how you would use a mobile scaffold tower to re-lamp all the light fittings in a supermarket. Use bullet points to give a step-by-step account of re-lamping the first two fittings. 

Prefabricated mobile scaffold towers Mobile scaffold towers are frequently used throughout industry. It is essential that the workers are trained in their use since recent research has revealed that 75% of lightweight mobile tower scaffolding is erected, used, moved or dismantled in an unsafe manner. 

The recommended height to base ratio varies from 3 1 to 3.5 1, with a base not less than 1 m, dependent on whether the tower is to be used outside or inside the building. The ratio is lower for outside use due to possible wind effects. The ratios quoted should be treated as a guide and the manufacturer s instruction should always be consulted. Mobile scaffold towers should be inspected regularly as outlined later in this chapter. 

Mobile scaffold towers should never be moved while people are still on the platform. This is a significant cause of accidents.
