LD40

LD40 is the lighter profile of the HD40R range, a 400 mm square aluminium truss with Ø50 × 3 mm main tubes and lighter diagonals. The v2 specification lists 25 × 3 mm braces in EN AW-6082 T6 aluminium, a weight of approximately 11 kg/m and the Sg2 (50 mm) connection system.

The HD40R range covers medium to heavy-duty applications with the HD40R, HD40 and LD40 profiles, all with a 400 mm square section. It is widely used for vertical tower applications, particularly within MT series truss systems: HD40 is commonly used in MT and MT-X structures, while HD40R is designed for higher-load, reinforced applications such as MT-EX.

Important Notes

  • Load capacities shown are applicable only to the corresponding loading tables.
  • Load values are based on static loading conditions unless otherwise specified.
  • The published load data applies to single-span configurations with supports at both ends.
  • Multi-span systems, custom structures, or special configurations require project-specific structural calculations.
  • Self-weight of the truss has already been included in the published load calculations.
  • Load ratings are valid only when the truss is installed in the orientation illustrated in the loading tables.
  • Connection forces and bending moments at joints are considered within the specified loading data.
  • Truss systems can be assembled using different standard section lengths to achieve the required span.
  • All installations should be carried out by qualified professionals in accordance with applicable safety standards and local regulations.
  • Always inspect truss components before use and replace any damaged parts immediately.
  • Refer to the Installation & Assembly Manual before assembly, rigging, or loading the truss.
  • For complex structures or critical applications, consult a qualified structural engineer before installation.
