Modular vibrating screeds BT-90, consisting of an electric, gasoline or pneumatic motor that powers the vibrating unit and metal screeding blades-modules (1, 2 and 3 meters long), fastened together with clamps. A special bracket can be installed on the pneumatic modules, which allows you to create a deflection of up to 15 degrees. The length of such a modular structure can be up to 25 meters. The construction of this type of vibrating bars has a very high rigidity even in the longest version, therefore the quality of leveling and smoothing of the surface is always at the highest level. The thickness of the fresh concrete to be compacted varies from 300 to 350 mm.
