Self-reacting mould for roof and floor beams

Self-reacting mould for roof and floor beams, with height adjustment from 30 to 100 cm and buffer element for millimetric tightening by about 6 cm at the sides so that the thickness of the shank can be altered from 8 to 14 cm. 
The buffer is held in position by oil-pressured cylinders in order to eliminate the need for anchorage beams at the sides. The entire system is designed to facilitate casting.
