The columns consist of a guide with integrated cylinders and a pressure hose (ø 4mm) to connect the elements. The height is adjusted using a hydraulic pump operated by a hand crank or an electric drive unit. The 4 m long high-pressure hose is already mounted on the column and vented to ensure easy assembly.
The columns TA and TU consist of two steel tubes. The guide tube is supported on bearings. These are used when there are high load and stability requirements.
