Approvals

Lindapter’s reputation is synonymous with safety and reliability, gaining multiple independent approvals

GIRDER CLAMP CONNECTION CONCEPT 

Maintenance engineers, contractors and specifiers working in the automotive and manufacturing sectors can take full advantage of these benefits. For example, production lines can be installed or reconfigured extremely quickly using Girder Clamps, minimising interruption to production which consequently saves time and money.

STEP 1 A location plate is positioned between the two sections to be connected. 

STEP 2 Lindapter girder clamps, bolts and other required components are installed. 

STEP 3 Each bolt is tightened to the recommended torque using a torque wrench.

Steelwork

Lindapter’s girder clamps are used to connect supporting or reinforcement steel to existing frameworks within production halls. 

This is particularly beneficial when a production line needs to be reconfigured or new machinery such as robotics need to be installed. 

Girder clamps are adjustable, allowing the installer to quickly align the steel, before tightening the clamps with standard hand tools. They provide a fast and convenient alternative to drilling and welding, while allowing connections to be easily disassembled in the future if the production line requires further modification. 

Key Benefits ✔ High strength connections for low, medium or high load capacity applications. ✔ Quick and easy to install, reducing production downtime. ✔ Easily disassembled during future modifications. ✔ No damage or weakening of existing steelwork.

Conveyors

Overhead and floor conveyor systems are widely used in the production lines of automotive and other manufacturing plants to improve production rates. 

Conveyors create dynamic loads during operation due to their continuous movement and changes in direction which can cause challenges for maintenance engineers installing or reconfiguring production lines. 

Lindapter has a range of clamping systems to overcome these challenges that are approved for use in dynamic loading applications and are the ideal solution for securing conveyors to the steel framework within manufacturing plants. 

Key Benefits ✔ Internationally approved for dynamic load applications. ✔ High strength connections for low, medium or high load capacity applications. ✔ Quick to install, reducing production downtime. ✔ Easy to install and adjust. ✔ Easily disassembled during future modifications

Machine Building

The machine building industry requires a flexible approach to the assembly of machinery which is often large and difficult to move. Production lines are constantly re-configured to accommodate building of different machines. 

Lindapter’s clamping systems are the ideal solution for securing production lines. The clamps are manufactured from high strength materials and are designed to resist high loads in tensile and slip. 

When the production line needs to be changed the clamps can easily be disassembled and moved with minimal time and effort. 

Key Benefits ✔ High strength connections for low, medium or high load capacity applications. ✔ Quick to install, reducing production downtime. ✔ Easy to install and adjust (or disassemble for re-configuration of the production line).

Crane Rails & Hoists

Cranes, crane rails and hoists are widely used in manufacturing plants and automotive production lines to ensure a steady workflow by lifting and moving raw materials and finished products effectively and safely. 

Dynamic loads can be present in crane structures during operation due to the movement of the hoist along the crane rail. 

Lindapter has a range of clamping systems that are independently approved for use in dynamic loading applications and are the ideal solution for securing crane structures and crane rails to the steel framework within manufacturing plants. 

Key Benefits ✔ Internationally approved for dynamic load applications such as cranes and crane rails. ✔ High strength capable of resisting high load requirements during lifting. ✔ Easy to disassemble during re-configuration of production line.

Mechanical & Electrical

Cable trays or equipment can be secured within production halls in simple girder clamp tensile arrangements, or in vertical column applications withstanding frictional loads. Fast adjustability allows multiple cable tray / ladder systems to be easily setup to intersect with each other. 

Applications include: • Cable trays and ladders • Piping and conduit supports • Instrumentation and associated cabling • Junction boxes and cabling 

Key Benefits ✔ Fast, simple installation saves time and money. ✔ Fully adjustable for a convenient installation. ✔ Safer connections with no need to drill or weld. ✔ Easily disassembled during future modifications. ✔ No damage or weakening of existing steelwork.

Structural Hollow Section

Lindapter Hollo-Bolts provide a unique solution for connecting to Structural Hollow Section (SHS). They are expansion bolts that only requires access from one side of the SHS, and offer a faster alternative to welding or through-bolting, enabling contractors to reduce construction time and labour costs. 

A typical connection is made by inserting the Hollo Bolt into the pre-drilled holes of the fixture and hollow section. As the bolt head is tightened, the cone is pulled up the bolt thread, causing the sleeve to expand until the cone locks the sleeve against the hollow section’s inner wall. At full tightening torque, a clamping force is established between the fixture and the steel section to form a secure connection. Applications in automotive and manufacturing plants include handrails, barriers and staircases but they can be used for almost any connection to hollow section. 

Key Benefits ✔ Internationally approved for dynamic load applications. ✔ Fast, cost saving installation from one side. ✔ For square, rectangular & circular hollow sections. ✔ High resistance to shear and tension. ✔ Unique High Clamping Force design (sizes M16 and M20). ✔ Low temperature tested to -45°C (carbon steel variants). ✔ Range of head types available

Project Spotlight

AUDI FACTORY UPGRADE INGOLSTADT, BAVARIA, GERMANY

Lindapter Girder Clamps provided a solution for upgrading car production lines.

Market: Automotive Product: Type A, B and AF Girder Clamps Client: Audi AG

Project Background Audi has been building cars at the Ingolstadt headquarters for more than 70 years. The site continues to develop into a networked digital factory with modern production systems and high-tech solutions enabling highly efficient, sustainable manufacturing. The plant is also getting ready for electric mobility, with measures to increase flexibility laying the foundation for the cars of the future.

Client Requirement In the past Maintenance Engineers had used a range of self-made and other manufacturers clamps when carrying out modifications to the car production lines. 

The engineers found that they had to spend a lot of time inspecting and tightening the clamps due to them loosening and twisting with vibrations and dynamic loads caused by the production lines. To reduce maintenance time the responsible engineer wanted to specify clamps that were approved for dynamic applications and compatible with locking washers. They also wanted to strengthen the existing connection points throughout the factory and install additional steel supports

Design Solution The engineer contacted Lindapter’s technical support team who provided assistance including connection drawings, technical advice and product testing. Solutions were proposed and accepted for several applications within the factory including: 

Overhead Conveyor System 2-bolt connection for “L” shaped hanger brackets to be connected to overhead steelwork that carry the car conveyor system. 

Supporting Steelwork 4-bolt connection for securing various sized vertical posts with end plates to existing steelwork to provide extra support. 

Strengthening Steelwork 8-bolt connection with location plate and beams joining together end to end, and at 90° to reinforce existing steel above. 

Other solutions included connections for beams at a 3° tilt, bracketry to accommodate height changes between two beams, and innovative shaped location plates for connecting non-aligned steel.

Each solution incorporated Lindapter Type A, Type B or Type AF Girder Clamps that have independent ETA / CE Mark approval for use in dynamic loading applications. 

Installation The Maintenance Engineers replaced all the existing non-Lindapter clamps and installed additional steel supports using over 5,000 Lindapter Type A & B Girder Clamps in various sizes (M12-M20) and over 500 Type AF Girder Clamps in size M16. The assemblies used grade 8.8 bolts installed through a range of pre-drilled bracket and end plate arrangements. The clamps with locking washers were quick and easy to install using simple hand tools and calibrated torque wrench, the clamps also had an anti-rotational design that prevented them from rotating during installation. 

Result Lindapter Girder Clamps provided a connection solution independently approved for dynamic load applications. The clamped assemblies are fully adjustable which gave the engineers the ability during installation to manoeuvre them into their final positions before fully tightening the bolts. Installation was quick, minimising interruption to production and downtime, whilst the connections can be easily disassembled in the future if the production line requires further modification.
