Extra Heavy Duty Truss

Extra Heavy Duty Truss

EHD

The Extra Heavy Duty offers superior load handling capabilities, making it ideal for use in large outdoor roof structures. It includes additional features that enable other roof interface components to operate efficiently with this product.

The Extra Heavy Duty (EHD) is engineered as a robust quad truss designed to support capacities exceeding those of the TFL Serious Heavy-Duty range. Constructed from high-grade aluminium alloy 6082-T6, it features a 50.8mm (2”) O/D main tube paired with TFL’s fork end jointing system, allowing for rapid and straightforward assembly.

Key Features

  • Material and Construction: Made from durable aluminium alloy 6082-T6, EHD assures strength and longevity. The use of 50.8mm O/D main tubes offers robust support for various applications.
  • Versatile Options: EHD comes in a wide variety of standard lengths, choose from standard section lengths of 1.0Mt through to 5Mt.
  • Load Capacity and Span: Capable of supporting large loads, EHD can be loaded to 2,247kg over an 18-meter span. This makes it ideal for outdoor roof systems requiring significant strength and stability.
  • Manufacturer Details: We are an EN1090, ISO9001, and JOSCAR certified UK manufacturer, adhering to strict quality standards. We operate within the global events technology industry.

As the demands of the industry continue to evolve, the EHD system is poised to meet those challenges head-on, providing the reliable support and flexibility needed to create unforgettable event experiences.

Key Benefits of the Fork End System

Fork end connections are a popular choice for aluminium trussing in the live events industry due to several key features:

  1. Ease of Assembly: Fork end connections generally consist of a female set of fork connectors on one side and a male set on the other. (Slick Nova beam and Nova Lite products combine both types on one end). This design allows for quick and straightforward assembly, as the modules can be easily slotted together and secured with truss pins by means of a truss hammer.
  2. Strength and Stability: These connections provide a robust and stable joint, which is crucial for supporting heavy loads such as lighting, sound equipment, and digital displays. The secure fit ensures that the truss structure remains stable even under significant weight.
  3. Versatility: Aluminium trussing with fork end connections can be used in various configurations, including straight segments, corners, and curved elements. This versatility makes it suitable for a wide range of applications, from stage setups to exhibition booths.
  4. Lightweight and Durable: Aluminium is known for being lightweight yet strong, making it an ideal material for trussing. The use of fork end connections does not compromise the truss’s overall durability, ensuring it can withstand the rigors of frequent assembly and disassembly.
  5. Aesthetic Appeal: The clean and professional look of aluminium trussing with fork end connections adds to the visual appeal of event setups. This is particularly important in the live events industry, where the appearance of the stage and equipment can impact the overall experience

These features make fork end connections a reliable and efficient choice for aluminium trussing in the live events industry, providing both practical benefits and aesthetic advantages.
