Description

Ledger is the main horizontal element of the scaffolding, used to create a spatial rigidity frame, transfer loads to the scaffolding standards and install handrails. It is a welded construction of steel pipes and die-cast parts, consisting of a round pipe with welded wedge heads at the ends. The wedge in the head is protected from falling out. It also secures the ledger to the standard.

The nominal length of the ledger is determined by the distance between the axes of the standards to which it is attached without additional elements. The ledger has a factory label indicating its nominal length.

Advantages:

• Metric interchangeable dimensions along the axes of the standards multiple of 0.25 m.

• A specially shaped wedge head allows working level decks to be placed without gaps, and has the SmartLock built-in function, which allows remote connection to the standard, speeding up installation and improving safety at height.

• The wedge head has a symmetrical shape to ensure equivalent joint strength amid oppositely directed loads. This simplifies design and reduces risks during assembly.

• Standard ledgers feature color-coded navigation. Each size has a unique color marking, which greatly simplifies element identification and speeds up installation. The color sequence corresponds to the arrangement of colors in the rainbow spectrum: the longest arc of the rainbow, which is red, corresponds to the longest ledger – 3 meters; the next ledger, 2.5 meters long, is marked in orange, and so on.

• The pipe diameter of the main scaffolding elements (standards, ledgers, diagonal braces, lattice girders, cantilever brackets, etc.) is 48 mm. This makes it possible to put them together in arbitrary points by means of standard couplers without additional dedicated elements.

• Compatibility with European equivalents.

• Spark- and fire-proof design.

• Corrosion protection is provided by hot-dip galvanization.

• 20-year lifespan.
