QTJ4-45 manual hollow concrete block machine is manufactured on the base of technical modification to the original block shaping machines,that is changing the former one -time-vibration into twice-vibration of moulding core.so ,the block density becomes higher,shaping speed quicker and block strenght more even, this model of machine can be suitable to the customers who have any kinds of existing cement working sites, and the consumption pallests can be reduced.
