Assembly and Dismantling Procedures
To Dismantle A BoSS Ladderspan Tower
Assembly Procedure - Mobile Towers - 3T Method
•
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:
•
Remove toeboards, and pass down the tower.
•
Unclip farthest end of braces and immediately go to protected trapdoor position on ladder to
complete removal.
•
Remove upper platforms from protected platform levels below.
•
Pass removed components out of the tower to a colleague.
Where all 3 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.
