  Structures Table with Standard Roof Truss

  This training unit is used to investigate loaded plane trusses and enables the member forces to be measured. A pre-assembled main truss is included. The trusses are assembled using joint discs to avoid bending loading. Seven of the members are equipped with full bridge strain gauges for the measurement of force. A strain gauge connecting box is included in which the offset error of the individual strain gauges is already compensated. The measuring amplifier FL 151 is required for measured signal conditioning. The loading device is mounted in bearings such that it can rotate, as a result it is also possible to apply forces at an angle. The unit is designed as an easy to operate table model. Another truss is available as an accessory, a laboratory trolley for storing the individual parts is also available.

  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.

  Cam Mechanism

  Cam mechanisms are used in many areas of technology, such as for valve control in combustion engines. The simple experimental set-up permits quick demonstration of the action principle, and can be used to demonstrate the influence of different cam shapes. The cam follower can work either as a roller tappet, cup tappet, or trailing lever. The stroke is measured using a mechanical position measurement gauge. A scaled disk indicates the associated angle of rotation.

  Shearing Force and Bending Moment Apparatus

  This demonstration unit facilitates the experimental investigation of the progression of the bending moment and shearing forces on a bar subject to point loads. In addition, the section principle commonly used in mechanics can be demonstrated. Due to the use of a low friction joint with two degrees of freedom at 1/3 of the span and two dynamometers, the measurements can be recorded directly from the bar. The deflection of the bar as 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.
