Mobile Tower Scaffolds

Mobile tower scaffolds are commonly used for jobs involving painting or maintenance, it is used to
access the height for short period, the structure is mounted on four wheels so it can move

frequently around the work area.

Mobile tower scaffold has one working platform with access ladder fitted insider and are light duty
scaffolds only. Normal scaffold tubes are used to construct this mobile tower scaffold, more often

proprietary made structures.

Except for special purposes, generally the height of the mobile tower scaffold is restricted to 12

metres. The base height ratio is 1: 3.5 for internal use, the shortest base dimension. When it is used
externally then the ratio is 1: 3. The base height ratio may be available in manufacturer instructions

as well. To add more stability, the mobile tower scaffold may be attached with guy ropes, rakers or
outriggers.

The hazards associated with mobile tower scaffolds are

• Structural collapse
• Fall from height

• Falling of objects

• Overturning while moving
• Unintentional movement of wheels

• Contact with overhead powerlines during movement
