In the engineering industry, the high-capacity testing is essential for the development of high-strength structures and components. The porticos are an essential tool in this process, since they allow the testing of structures both static and dynamic.
Static Gantries
Static gantries are structures that are used to apply loads to a structure or component in a constant manner.at low frequencies or speeds. Ideal for endurance testsThey measure the amount of force that a structure or component can withstand before failure. These gantries are capable of applying loads linearly or cyclically, which makes them ideal for large capacity testing.
At Servosis, we manufacture static gantries for strength testing of high-strength structures and components such as beams, columns and steel structures.
Dynamic Gantries
Dynamic gantries, on the other hand, are structures that are used for to apply repetitive loads with high frequenciesup to 50 Hz, on a structure or component in one or more directions. These gantries are ideal for fatigue testing, as they allow simulating the amount of stress that a structure or component would experience during its lifetime. Fatigue testing is essential to ensure that the tested products can withstand repetitive load cycles without failure.
We use these dynamic gantries to perform fatigue tests on a variety of products, such as automotive parts, packaging, concrete, fiber, metallic structures...
In recent years since Servosis we have supplied this type of gantries to numerous Universitiesand have been awarded numerous public tenders. This fact shows the quality of the product, its versatility and its capacity to adapt to the requirements of each case.
Below, we present you our ME 406 gantry and its main characteristics;
Structural testing.
Gantry ME 406
ME 406 is our model of gantries for load tests on large structures such as beams, columns, steel structures, bridges and other similar components.
One of the fundamental differences of our 406 series with respect to other designs is that our proposal is based on the use of columns and load bridges with automatic hydraulic displacement and locking system and not on the use of beams.. This design greatly simplifies test preparation operations and eliminates the need for auxiliary elements such as overhead cranes.
The anchoring system of the large gantries to the available surface is adapted during the design phase, in general a slab should be available with holes drilled to fixed distances. In this case, the holes in the slab are used, and the gantry is connected to the floor by means of a threaded bar system.
It is also very common to use the lower area of the slab for the installation of the hydraulic power unit, and some of the free holes for the hydraulic conduits. In this way, a clean system is achieved where there are no impediments for the assembly of the tests.
Features of the ME 406 gantry
This model has a number of features that make it ideal for the realization of load tests on large structures. These features include:
Specific design for large specimens, the design is adapted in each case to the customer's specifications.
Hydraulic drive:
- Double acting hydraulic servo actuator installed on the upper loading bridge.
- Possibility to install more than one actuator and work synchronized.
- Actuator control by servovalve.
- Automatic vertical positioning of the loading crossbeam.
Force parameters
Maximum load capacity - Models from 50kN to 2500kN available.
Transducer for force measurement - Load cell, Class 1 according to ISO 7500.
Displacement parameters
Transducer for displacement measurement - Integrated in the servoactuator body. SSI type digital output signal.
ME 406 gantry applications
The ME 406 gantry is used in a wide variety of applications in the construction and engineering industry, such as the evaluation of strength and load bearing capacity in;
- Building load testssuch as walls, masonry, concrete slabs, etc.
- Load tests on steel structuressuch as bridge trusses, bleachers, etc.
- Load tests on machinery components, such as crossmembers, seats, wheels, crankshafts, automotive and railway parts, etc.
- Furniture testing.
The ME 406 gantry of Servosis is an essential tool for testing large structures. With its load capacity of up to 250 tons, its automatic load control system and its high accuracy, the ME 406 gantry is ideal for a wide variety of applications. Its modular design and integrated safety system make it a versatile and safe tool for testing in different locations.
Accessories for structural testing
In addition to the gantries themselves to carry out these tests, we also have a wide range of accessoriesand all of them can be custom made;
- Clamps.
- Extensometry.
- Videoextensometry.
- Bending tooling.
- Compression.
- Pull out.
- Climatic chambers.
- Ovens.
In conclusion, heavy-duty testing gantries are essential to ensure that products are safe, reliable and durable. Static gantries are used for strength testing, while dynamic gantries are used for fatigue testing.
For each project, Servosis studies and develops a specific tailor-made solution, we offer our customers the right product.
