In the realm of construction and engineering, the efficient connection of structural elements is paramount for safety, stability, and ease of assembly. Lindapter Girder clamps, sometimes called beam clamps, stand as a testament to innovation in this field. In this introductory guide, we delve into the intricacies of Lindapter Girder Clamps, exploring their functionality, advantages, and the diverse range of products offered by Lindapter.

What are Lindapter Girder Clamps?

Lindapter invented a type of mechanical steel connector system designed to securely connect steel beams, girders, and other structural components without the need for welding or drilling. This innovative solution offers a versatile alternative to traditional connection methods, such as bolting or welding, allowing for rapid and efficient assembly of structures in various industries including construction, infrastructure, and industrial applications to name a few.

How do They Work?

The operation of Lindapter Girder Clamps is a simple and effective process. These clamps utilize a unique design featuring a series of components that allow the nose of the clamps to grip onto the flanges of steel beams or girders. This gripping action is achieved through the tightening of bolts, which compress the jaws against the beam flanges, creating a secure and stable connection.

One of the key advantages of Lindapter Girder Clamps is their adjustability. Unlike fixed connection methods such as welding, Lindapter clamps allow for precise alignment and adjustment during installation, accommodating variations in beam dimensions or alignment errors.

Advantages of Lindapter Girder Clamps:

ICC-ES Approved: Lindapter’s Type AF & AAF Girder Clamps are ICC-ES approved and compliant with the International Building Code for structural and seismic designs, per ESR-3976.

No Welding or Drilling Required: Lindapter clamps eliminate the need for hot work permits, specialized welding equipment, and the associated safety concerns and costs.

Time and Cost Savings: By eliminating the time-consuming processes of welding or drilling, Lindapter Girder Clamps contribute to significant time and cost savings during construction or installation.

Adjustability: The ability to adjust and realign connections during installation simplifies the assembly process and ensures precise alignment of structural components.

Non-Destructive Installation: Lindapter clamps can be installed without causing damage to the beam's protective coatings or structural integrity, preserving the integrity of the structure.

Versatility: Lindapter offers a wide range of clamping solutions designed to suit various beam sizes, profiles, and applications, providing flexibility for diverse construction projects.

Lindapter's Catalogue

Lindapter offers a comprehensive variety of Girder Clamps tailored to meet the specific needs of different industries and applications. Some of the key products include:
