GENERAL
The Hydramax lifting system ensures a smooth and synchronous lifting of the trailer roof, since all of the connected cylinders will rise simultaneously. This makes the system very suitable for lifting roofs with a very stiff structure which are vulnerable to twisting and wringing.
Important notes
The only way to lift both sides of the roof separately using Hydramax, is to use two complete Hydramax 2 systems, one for the left side and one for the right side. In this case, the maximum lifting height is always 500 mm; the 1000 mm lifting height option is not available in this configuration because this will put too much stress on the mechanical parts when lifting only one side of the roof. The maximum input air pressure for the Hydramax 4 and 6 is 10 bar , the maximum pressure for the Hydramax 2 is 6 bar . This means that it’s not always possible to connect the pump directly to the air supply of a truck or trailer, please check this before installation.
In case of Hydramax 2, the use of a regulator to reduce the pressure to 5 - 6 bar is always necessary!
