Deck to Deck O Ledger( Transom)

Ringlock scaffolding has special parts of the deck-to-deck transom.  One type of the deck to deck transom is the O ledger deck-to-deck. I will give you details about what is the O ledger deck-to-deck transom. The sizes and the differences with other deck-to-deck and deck-to-ledger transom.

Deck to deck O ledger is a component used to create opening, access and conversion in the middle of the scaffold platform of the scaffold structure with two security flaps at two ends of a scaffold tube.  

In scaffold construction, the deck-to-deck O ledger is fixed to the flanks of two sides of the scaffold platform by two C pressings and locked by the flaps. The flaps keep the stability and security of the deck-to-deck O ledger.

Deck-to-deck O ledger is a popular component for the European standard ringlock systems (called Allround scaffolding).  They normally work with 320mm steel decks but the decks must be with O hooks.

  1. Size: 0.32m, 0.64m, 0.96m
  2. For Plank: 320mm Layher type
  3. Diameter: OD48.3mm
  4. Standard: EN 12811
  5. System: Allround Scaffolding System
  6. Brand: Wellmade

 

Why O-Hooks Planks & Decks?

Deck-to-deck O ledgers are only able to work with scaffold plank and hatch with O hooks. The reason is between the two ends, it is made of OD48.3mm round scaffold tube. O hooks can match up the size of OD48.3mm.

Loadability of the Deck to Deck O Ledger Transoms

Loadable of the deck to deck O ledger can be a load class 3 of EN12810 standard.   They can work with scaffold planks/decks in lengths from 0.73m up to 3.07m.

Sizes of the steel deck to steel deck O ledgers

There are three sizes of the deck-to-deck O ledger.

  1. One Board Deck to Deck Ledger: space of the transom allows one width of scaffold planks
  2. Two Board Deck to Deck Ledger: space of the transom allows two widths of scaffold planks
  3. Three Board Deck to Deck Ledger: space of the transom allows three widths of scaffold planks

Deck-to-Deck O Ledgers VS Deck to Deck U Ledger

Deck-to-deck O ledger and deck-to-deck U ledger are both types of deck-to-deck transom. Both of them are connected to the flanks of 320mm scaffold planks in the ringlock system to create the opening and access in the middle of scaffold platforms.

The difference between the deck-to-deck O ledger and the deck-to-deck U ledger is the material used for the middle space between the two ends is not the same.

  • O ledger is made of an OD48.3mm scaffold tube
  • U Ledger is made of a special U profile section

You know the middle space of the deck-to-deck transom(both O ledger and U ledger) is used to place scaffold decks. If the middle is an OD48.3mm scaffold tube, planks must have O hooks.  If the middle is made of a U profile, the plank’s hooks must have U hooks.

Deck to Deck Transom VS Deck to Ledger Transoms

The deck-to-deck transom and the deck-to-ledger transom function are the same. Both of them are used to create openings and access in the middle of the scaffold platform structure.

Deck-to-deck transoms are needed when connecting to the scaffold platform on both sides.

Deck-to-ledger transoms are needed when one side is a scaffold platform and another side is scaffold O ledgers.
