FIELD: building, particularly testing equipment to perform beam structure testing. ^ SUBSTANCE: device has base, support posts and loading means. Loading means is adapted for alternating loads application and is provided with reverse mechanism. Reverse mechanism is made as two pairs of vertical pull rods connected one to another by two cross-arms. One pair of vertical pull rods is fixedly connected to the base, another one may be connected to beam structure. Cross-arms are installed one above another and extend in horizontal direction. Discrete load transducer is installed on lower cross-arm. The transducer may be made as hydraulic jack. Each pull rod has adjusting nuts to regulate free cross-arm and pull rod movement and to change direction of load application. ^ EFFECT: possibility to apply alternating loads to object to be tested. ^ 2 l, 3 dwg |
