Ringlock Transoms

Provide rigid, high-capacity platform support with Dynaton Ringlock Transoms (Board Bearers). Certified in full accordance with Australian scaffolding standards (AS/NZS 1576.1 & AS/NZS 1576.3), these heavy-duty transverse structural beams form the primary load-bearing foundation that supports steel boards, timber planks, and working deck loads across modular Ringlock scaffolding bays.

Fabricated from high-yield structural steel and protected with heavy hot-dipped galvanising to AS/NZS 4680, Dynaton transoms incorporate an engineered back-to-back angle channel profile. This unique design holds scaffold planks captive between adjacent transoms—providing automatic positive location during deck installation while preventing lateral board movement or dangerous displacement under heavy site traffic.

Key Features

• Engineered Captive Plank Seating: Unique back-to-back angle profile creates a secure recessed pocket that locks scaffold boards into position, preventing shifting and trip edges.
• High Vertical Load Capacity: Reinforced beam section delivers superior bending strength to carry heavy masonry, materials, and multiple tradesmen safely.
• Instant Wedge-Lock Assembly: Cast steel ledger heads welded at both ends drop effortlessly into standard Ringlock 8-hole rosettes, securing rigidly with captive wedge pins.
• Certified AS/NZS 1576 Compliance: Engineered and tested to meet Australian structural standards for heavy-duty commercial construction and civil access.
• Hot-Dipped Galvanised Protection: Thick, uniform zinc coating ensures long service life with zero maintenance across demanding coastal and industrial environments.

Applications & Safety Guidelines

• Primary transverse board bearers for standard platform bays, cantilevered hop-up bracket extensions, stair landings, and intermediate deck levels.
• Commercial construction, industrial maintenance towers, civil bridge access, and heavy falsework shoring.
• Safety Notice: Ensure transoms are installed horizontally and fully locked into rosettes before laying planks. Inspect plank seating channels to ensure zero debris prevents full board engagement.
