Assembly Procedure
Mobile towers - 3T method
Assembly and dismantling procedures
When building a boss tower:
●
To comply with the Work at Height Regulations we show
assembly procedures with platforms every 2 metres in height,
and, the locating of guardrails in advance of climbing onto a
platform to reduce the risk of a fall.
●
All platforms feature double guardrails on both faces of either
individual platforms or fully decked levels.
●
All guardrails should be 2 and 4 rungs (0.5m and 1.0m) above
platforms.
●
Never stand on an unguarded platform positioned above the first
rung of a tower. If your risk assessment shows it necessary, you
may also need to guardrail platforms at this level.
●
Always start building with the smallest height frames at the base
of the tower:
Platform height in metres
1.7, 2.2, 3.7, 4.2, 5.7, 6.2, 7.7, 8.2, 9.7, 10.2, 11.7, 12.2
2.7, 4.7, 6.7, 8.7, 10.7
1.2, 3.2, 5.2, 7.2, 9.2, 11.2
Where all three frame heights are used in a tower, start with 4
rung frames at the base, with the 6 rung frames next and the 8
rung frames on the top. Refer to the quantity schedules for detail.
