  Shearing Force Apparatus

  This demonstration unit facilitates the experimental investigation of the progression of the shearing force in a bar subject to point loads. Also the section principle commonly used in mechanics can be demonstrated. Due to the usage at 1/3 span of a low friction joint sensitive to shearing forces and a dynamometer, the measurements of shearing force on the bar can be recorded directly. The deflection of the bar as a result of the travel of the dynamometers and the horizontal alignment can be compensated and regulated using two adjustment bolts. The bar is loaded with graduated sets of weights that can be attached at any point on the bar. The support rollers are equipped with ball bearings

  Experimental Set Portal Frame

  The set is intended for use with the universal test frame and demonstrates the elastic deformation of loaded frames. The test specimens are a U-shaped and and S-shaped frame made of steel with a square cross-section. These are subjected to varying loads using sets of weights and the resulting deformation measured. For this purpose, the set includes two precision position measurement gauges. The bearings can be either fixed or free enabling the frames to be evaluated as statically defined or undefined systems. The experimental set-up is quickly and securely assembled using special clamps.

  Torsion Testing Machine 200 Nm Motor Driven

  The unit is used for torsional testing of different materials to fracture. Test moment and angle of twist are measured. Bars of different length and diameter are used as specimens. The moment is applied using a reduction geared motor that provides four different drive speeds via the frequency converter. A strain gauge measuring shaft provides the moment as an electrical signal, the angle of twist is recorded by an optoelectronic angular encoder. Both values are displayed on a LC display. The moment is transmitted to the test bars using commercially available hex sockets. For adaptation to different length probes, the dolly can be slid. The base plate is reinforced against twisting with square sections. A transparent plastic cover provides protection against flying debris on fracture.

  Universal Testing Frame 400kN

  This testing frame is primarily used for loading experiments on components from steelwork and civil engineering. It is specially designed for large components in 1:1 scale. The design with its double frame and intermediate space permits specimens longer than the size of the frame opening to be investigated. It this way the possible uses of the testing frame are almost unlimited. The frame components are manufactured from U section St52. The corners of the frame are formed by joints rigid to bending, each is fastened together with 9 high-strength bolts. The testing frame is delivered in pre-assembled modules; it is assembled on site and placed on four adjustable, vibration damping bearings. The hydraulic ram systems available as accessories are on rollers and can be positioned as required within the frame.
