Synchronizing hydraulic cylinders is provided by interconnected double-acting cylinders with dual pistons and central dividers which, with the pistons, divide the cylinders into four chambers. The outer chambers drive the pistons and the loads attached to the piston rods. The inversely interconnected intermediate inner chambers synchronize and balance piston and load movement. In double piston divided cylinders opposite outer chambers move a connected load and reversely connected inner chambers synchronize the load.
