Selflock frames are light and easy to handle and are ideal to gain quick
access to elevated positions.
Towers can be erected in a short time by two unskilled workers.
Uses of towers as access
- Electrical work
- Plumbing
- Seating stands
- Maintenance
- Plastering
- Painting
- Column erection
Below is a list of the maximum free standing heights allowed based on
maximum base-to-height ratio
Inside static towers 4 x min. base dimension
Inside mobile towers 3.5 x min. base dimension
Outside static towers 3.5 x min. base dimension
Outside mobile towers 3 x min. base dimension
When the safe base-to-height ratios are being exceeded or there are high
lateral loads the tower should be tied securely to the structure with
scaffold tubes and fittings.
Note
Towers can extend to 30m (150’) if tied in correctly.
Mobile tower castors must be locked when the tower is in use. The tower
can be moved on jack castors which must be locked when the tower is in
use.
The following items are the most common components used with the system.
