TESTING MACHINES AND EQUIPMENT
Electromotive testing machine for tension and compression (3 TEST AXES)
The test machine has three load axes with a load capacity of 250, 50 and 10 kN for compression and tension. The maximum possible test specimen height is 75 cm. This machine is characterized by a very high accuracy.
TENSION-Compression-TEsting Machine
These machines are two load frames which have a load capacity of 100 kN (left) and 1 MN (right). The machines are predominantly used for the determination of uniaxial material behaviors, for example the tensile strength of various materials. However, they can also be used for compression or tensile testing of smaller components.
Hydropuls testing machine
The Hydropuls testing machine has two load frames: one with 250 kN and one with 1 MN load capacity. It is used for the dynamic loading of test specimens, whereby all frequencies relevant for civil engineering are possible.
Tensile testing machine
This machine is used to test tensile members (ropes, cables and chains) up to a maximum load capacity of 400 kN and a maximum length of 12 m, for example members for bridges or prestressed concrete containers.
Pulsator and steering
The pulsator system is used to generate dynamic loads. The various existing cylinders are connected to them in order to create dynamical loading for components or the like. The pulsator system is used, for example, for testing railroad track sections or paving linings for road construction.
Large strong floor
On the large strong floor (21 m x 6 m) several portals with test cylinders of different sizes (from 100 kN to 1 MN load capacity) and the associated control consoles are arranged for flexible design of tests. The strong floor is used predominantly for testing of large components, for example facade elements, entire bridge parts, bored piles, complete structural nodes and the like. The individual elements can be up to 10 t heavy and 5 m high.
Small strong floor
The small strong floor is similar to the large strong floor. However, the test cylinders have a capacity of 100 and 200 kN. Here components with slightly smaller dimensions are tested than on the large strong floor.
Compression testing machines with different capacities
These are three compression testing machines. Two of these compression testing machines have a capacity of 6 MN with a possible test specimen height of 4.0 or 1.5 m. They are mainly used for the testing of high components made of steel, masonry, concrete or wood. The third compression testing machine has a capacity of 3 MN and is mainly used for standard tests, for the determination of the compressive strength and modulus of elasticity on routine test specimens (cubes and cylinders). The test specimens for this machine can be a maximum of 0.6 m high.
Triaxial testing machine
This testing machine can simultaneously load a test specimen in three axes. These types of loading are particularly relevant for cooling towers, reactor pressure vessels, dams and offshore structures. The load capacity is 5 MN for compression and 500 kN for tension per axis. As test specimens, cubes with an edge length of up to 30 cm can be tested. With this technical data, this machine is one of the few in the world.
Small-scale devices
Layer thickness measurement
The DUALSCOPE® MP20E-S is a battery-operated hand-held measuring instrument with plug-in probes for layer thickness measurement. It operates both according to the magnetic induction method according to DIN EN ISO 2178 and the eddy current method according to DIN EN ISO 2360. The RS 232 interface allows the documentation of measured values via a PC or printer.
measurable layers:
- Non-magnetic layers on a ferromagnetic base material (with the magnet-inductive method according to DIN EN ISO 2178, -ASTM B499), for example zinc, chromium, copper, tin or paint, varnish, plastic, enamel on iron or steel.
- Electrically non-conductive layers on non-ferrous metals (with the eddy current method according to DIN EN ISO 2360, ASTM B244), for example, paint, lacquer or plastic on aluminum, brass or zinc, and anodized layers on aluminum.
- The measurable layer thickness range is 0 ... 1500 μm depending on the probe currently in use.
