Hydraulic Cylinder and Balance System of QFT6-16 Concrete Block Making MachineA is for the main hydraulic cylinder of the concrete block machine, it is used to up and down the block mould. When the vibration table vibrates to form the blocks, it is also could mix the mould.B is the hydraulic cylinder of the mould. It is used to up and down the concrete block mould.C stands for the synchronous axis. There are 2 synchronous axes beside the QFT6-16 concrete block making machine to keep synchronous when the mould up and down.D is the guide axis. There are 4 guide axes beside the concrete block making machine. These axes would absolutely keep block mould in one horizontal plane.
