SCAFFOLDING ERECTION GUIDELINES STEP 4
1. Ledgers and Transoms can
now be placed at the required
levels for the first lift.
2. It is recommended to use
Truss Ledgers (Transoms) to
support heavy duty working
platforms as necessary.
SCAFFOLDING NOTE:
There are several types of Ledger
available to support Planks:
A 0.88m Ledger is unreinforced
and will support three Planks
and provide the minimum width
of scaffold in accordance with
MS1462, BS EN 12811 and will
generally support up to Load
Class 4, although Load Classes 5
and 6 can also be supported.
Truss Ledgers span from 1.57m (5’-2”) up to 3.05m (10’-0”) and carry varying loads
depending on use and width of platform. The maximum capability of each type of
Ledger is detailed in the Technical Manual.
