This is the layout for the top roller and chain drive. The roller is moved up and down hydraulically. A double acting hydraulic cylinder is connected to another double acting cylinder on the wedge. When the cylinder that actually moves the roller up and down oil is transferred from the other cylinder connected to the roller frame to the cylinder on the splitting wedge. The hydraulic hoses connect directly from one cylinder to the other. No pressure line from pump is used. Either there is a connecting cylinder between the cylinder on the roller and the one on the wedge so the same amount of oil is tranferred to the correct side of the wedge cylinder or two double ram cylinders are used. It is the same method used to synchronize two cylinders with and uneven load. If the three cylinders are used then there is a connection to pressure and to tank.
