Abstract

A hydraulic arrangement. The hydraulic arrangement has multiple hydraulic units, the control units of which are connected, in particular in series, via a data connection. The control units are preferably designed to control selectively only hydraulic cylinders directly associated with said units, or also indirectly control, via the data connection and the control unit of an additional hydraulic unit, the hydraulic cylinders associated with said additional hydraulic unit. A climbing formwork having at least one climbing unit, in particular multiple climbing units. The hydraulic units can be linked via the data connection such that synchronous lifting and/or lowering of all climbing units can be or is achieved. The hydraulic units are preferably connected in a master-slave arrangement or are preferably controlled in a master-slave mode. Also preferably, the hydraulic units are designed to switch from the master-slave mode to the stand-alone mode.
