With the ULBRICH shock absorber test machine shock absorber can be tested according theisr individual mouting position. The test run is based on the OEM specifications, the National Railway Regulationss and/or in accordance to the European Norm. It is essentialy an impact with a sine wave speed profile. According to his demand the customer can choose between a pure shock absorber test machine or combination of shock absorber and spring test machine. › download movie (MP4, ca. 26,4 MB)

Ulbrich spring test machines are developed specifically for the railroad-industry. They are in the use in workshops as well as at spring manufacturers. Beside the classic coil spring, leaf springs, parabolic-feathers and also rubber springs be tested a the same machine. According to implementation, the axial stiff-ness as well as the transversal (horizontal) stiff-ness and its direction can be measured.ir direction. An individual test-programs can be in simply way produced with our software.

Our Buffer Test Machines are based on the OEM specifications, the National Railway Regulationss and/or in accordance to the European Norm EN 15551, testing of static characteristics of buffers. The test run in accordance to this Norm requires the plotting of a force-distance curve during the entire press cycle. The test is carried out using a complete buffer system.

Mobile Puller with 100 to press force with integrated acetylene-compressed air ring burner or high pressure hydraulic power pack. The solution with integrated acetylene-compressed air ring-burner is specially developped for wheel-disk without oil-pressure-drilling. While the solution with the high pressure-hydraulic power pack is put into action on wheel-disks with oil-pressure-drilling. It is also possible to have a puller with both solution combined.

The lifting equipment consists of two mobile boogies. Integrated within the superstructure is a hydraulic power pack which drives the two hydraulic cylinders. The cylinders are situated in the highly robust and laterally adjustable lifting blocks. The lifting blocks and the jack contact surfaces (lifting points) can be repositioned along the cross-beam via a spindle. This allows the flexibility to lift and control a number of different types of Locomotive and carriage. Once the carriage has been lifted, the lifting blocks can be locked out using safety bolts which ensure that the height selected is safely maintained. The position of the safety bolts themselves can also be controlled by sensors. An optional function to weigh and calculate the centre of gravity is available upon request. Here, the lifting blocks have been fitted out with “load cells“, which can transfer the load input into a unit of weight. With the accompanying software these values can be evaluated in order to determi
